The British are coming! At least to #Data16

Otherwise known as the Viz which shows who is going out to the Tableau Conference 2016 #data16 on the British Airways flight BA191 on Saturday 5th November.

A few weeks ago I tweeted out to see who was on my flight –


I got quite a few replies and it looks like there are about 25 of us going and it got me thinking to how many of the community on the flight will know of each other but not actually met each other.  So what better place than a 10hr flight to meet someone new and discuss all things Tableau?

So I set up a Google Form, which populates a Google Sheet to capture the details of who is flying (You can complete the form which is embedded below if you are on our flight)


I then downloaded a seat map of the aircraft which flies the route – a BA 787-900 series with four classes, First, Club, World Traveller Plus and World Traveller.


Finally I mapped the coordinates, something I first did at easyJet, blended with the Google data and I now have an interactive seat plan where you can see who you will be sitting next to or where that member of the community is that you always wanted to talk to but were too afraid to ask!

The great thing with the Tableau Public Google Sheet connector is that it refreshes daily, so it will update automatically, which is great for the dashboard which I also built using device designer for the first time as feel that the Mobile experience is the best for viewing this.

The final touch is that you can go back in and change your form, should you decide to move seats.

Can Tableau really change your life?

Can Tableau really change your life?

Well, you hear a lot on Twitter and blogs about how Tableau has helped people to really see and understand their data, and changed people’s lives in moving from Excel treacle to worksheet and dashboards, fast iterations and rapid prototyping, all with claims around Tableau changing people’s lives, but actually, in those instances it really has enhanced them rather than changed them.

I want to share my journey below and explain how Tableau Software really has changed my life.

I am now 43 years of age and have been working for 26 of them (I know what you are thinking – he really doesn’t look that old), during which time I have had three pretty distinctive career fields –

  • Retail
  • Accountancy
  • Business Intelligence

Now little did I know, when I started out pushing trolleys at the weekend in my local supermarket where that would take me and how I have always been seen as ‘the data guy’ without realising it throughout my career.

As I progressed through the rank and file, I can remember becoming the Manager with the accountability for the figures and communicating this to the wider team.  No real tools were available then, so it was down to a 20ft long sheet of brown paper, segmented into each department and the key metrics, and using different coloured post it notes to indicate performance vs. plan with the figures annotated on the notes.

(a bit like this)

This eventually got me a position in head office as a Finance Analyst for our convenience stores.  My role was to help ‘show the numbers’ and put context on what was going on. Our systems back then were very basic and green screen based.  Text based data, hard to extract and do anything informative with.

I remember building a sales graph by department which took ages and I was really proud of , which would have looked like this

Year to date sales.png

But as my manager pointed out, how can they really read this as it is too busy.  This got me thinking about the way I visualise and how I can improve it – btw I also produced something like this and was extremely proud with myself that I found an online plug in that would let me label every element of the pie #puffschest


I started to research graphing best practices and improved my offering to the business, but not before destroying the rules of the ink to non data ink ratio making everything bold and black on the screen which I could!

The visualisation which really got my work on the radar, was an excel plug in which allowed me to build a treemap.  I had seen one on a BBC science programme, and thought it was a great way to visualise a large amount of data on the screen – up until this point I had used bars and scrolled left to right !!!

I produced something like this

Not earth shattering, but at the time quite forward thinking.

Fast forward a few years and I am an Accountant at easyJet looking after our Commercial and Network divisions.  We were a sea of Excel tables and poor visualisations.  I thought that it would be a good opportunity to bring back the treemap to visualise all 650 routes across 25 bases onto a single view.  This time though, I didn’t want to use Excel but thought that there would be a better way.

A quick Google introduced me to two things – The words ‘Business Intelligence’ and a product by a company called HIVE which natively built treemaps.  The definitions I read of Business intelligence resonated with what I had been trying to achieve throughout my career without realising it was a field in its own right.

The product by HIVE was interesting, it only built treemaps and was used by the US Army to look at inventory in the battlefield.  It also had Dr Ben Schneiderman on its board of advisors, the man who invented the treemap.

Although the treemap was useful, through my research I discovered some other tools and eventually settled on using ……… Omniscope.

Omniscope was UK based, provided treemaps as well as a number of other chart types including network graphs and also had built in ETL functionality (something else I had to Google!).

My CFO was impressed with the demo I built and I was allowed to purchase 5 licenses and training for the team.  The company we partnered with for this was called Atheon, run by Guy Cuthbert.  Following the initial work, we looked at doing a larger piece of analysis and gave Atheon two years worth of our bookings data as well as a number of other data sets which we had not blended on before and asked what they could come up with.

When Guy presented back, he used Omniscope and introduced another tool called Tableau.  Now I have to admit, when I first saw Tableau, I wasn’t impressed.  It was version 7.0.  It did not have treemaps.  It did not have ETL capability.  I needed a server to share the output?  Sounded like a con to me.

So I plugged away with Omniscope and was working on a new product that easyJet was about to launch and was exploring with the data generated.  The project was allocated seating.  I used a custom background map to build this


And then used animation to show how the seat sales on the aircraft built up prior to departure.

We was introduced to a few new features coming in Tableau 8, primarily treemaps.  We got a trial desktop licence (actually two) and a trial of server, which we couldn’t get IT to help with or support so we installed it on a desktop tower PC under the desk, shhhh. 😎

A colleague and myself built a few visualisations and we purchased a few desktop licences. He brought in a contractor for a few days who was skilled in Tableau to build things faster. She worked for a company called The Information Lab.

I remember having a conversation with our Tableau sales representative at the time about potentially purchasing another 15 desktop licences and I asked if we could be put in touch with other customers / airlines to share experiences and help with our business case and being told in no uncertain terms that if I buy the licences they will put me in touch, otherwise I am wasting their time!

I really was not feeling enamored with these Tableau folks.

However over the next week or so, something strange happened.  I started to fall in love with Tableau.  Compared with Omniscope it felt modern.  It was fast.  I could iterate and try and fail and try again.  I had another conversation with Tom Brown, the founder of The Information Lab.  he came in and we agreed to run a two day training course for our new users and we purchased the additional licences.  I discovered his passion for Tableau and the Information Lab’s journey and was also impressed by his teams skill and ability to support us.

At the same time, easyJet was embarking on its BI journey.  My boss was in charge as it was deliberately a Finance led and not IT led initiative.  I was asked to be full time on it and manage the project.  We partnered with Deloitte to help us with this and I also spent time with Gartner, using their research to help up develop our Centre of Excellence, show us how to deliver self service BI and also to define what the Analyst of Tomorrow should look like.

Here is a Prezi which I presented at the internal Tableau Sales Kick Off in 2014.  The audience looked like this –


Click on the image below to go into the Prezi




As you can see, we covered a lot more than just Tableau, developing a colour palette as well as visualisation standards and best practices, as well as what would be different for our analysts and how they will evolve in the future – all of which I will cover in a later blog post.

The team developed and we had nearly 80 desktop users, a 16 core server and thousands of users.  Our CoE was regarded by peers and people in the know as being one of the best in the world.

Another area which helped with this was leading the London Tableau User Group alongside Paul Banoub and Nick Bignell.  This increased my presence in the community as we often fill 150-200 seat venues with a similar number of people on our wait lists.  We have hosted two #datapluswomen sessions, had industry renowned speakers as well as senior employees of Tableau themselves presenting, including Elissa Fink and Francois Ajenstat.

I use Twitter as my primary tool to learn new things in Tableau as well as the data visualisation sphere.  This has also helped to increase my presence within the community.

At the turn of this year, the easyJet CoE was doing a great job and launching some fantastic new Tableau dashboards.  We had some changes though.  Our long term Head of BI had moved on and due to budget constraints was not directly replaced however our recently created Head of Data Science took over.

I had been thinking about a change of role around the same time.  My daily commute took four hours, I had a very energetic (who doesn’t) two year old daughter, and these combined didn’t really go well together.

My CV was old, like six years old as I had not changed it or Linkedin since I joined easyJet, so I subtly made adjustments to it and put the word out to a few influential people in the BI community that I might be available for the right role, should it come up.

When adjusting my CV, I wanted to change it from a standard text document to something more vibrant and creative which could demonstrate some of the work my team and I had achieved.

I looked on CV sites for guidance and settled on hloom and specifically their creative and portfolio templates.  Originally designed for photographers, I thought that would be perfect to showcase my Tableau work.

The next few months were a bit of a whirlwind to be honest.  During this process there was only one role which I spotted online and actually applied for – this was with a leading technology company and I had two interviews which went really well, before they decided to withdraw the role due to a change of direction.

Through word of mouth and introductions from the BI community I had several discussions with companies about potential roles they either had, or wanted to create following our discussions and a standard presentation I give on the work that my team had done and how every company could benefit from this BI focus.

I even had a discussion with the retailer where my career began!

In the end, I had four firm offers for roles on the table, all from meetings and general chats and discussions.  Not all of them had formal interviews.  It was a very surreal process.  One was from a prominent retailer, another from a property company, a third from an airline and a fourth from the Organisation I am now working for.

The roles were varied and at the time, newly created and unadvertised.  I found that my reputation and previous work had gone a long way to convincing companies of the need to improve their BI offering, which my presentations and discussions only further cemented.  The roles ranged from Centre of Excellent Manager, to Head of BI, to Head of Insights and Global Director of Business Intelligence.

During our conversations, I felt that even for the companies I turned down roles with, their BI journey’s would be enhanced as I offered suggestions and partnerships to help drive them forwards, which I know at least two have carried on with.

The role I took came about via a strange course, and originated with an email to Tableau from my predecessor, asking ‘can you put me in touch with someone in the London / UK market for sourcing a Tableau Rockstar that we could secure for a leadership position’


This found its way to Tom Brown with a little more detail and was forwarded to me.  At the time, I was a long way down the road in discussions with one of the other companies, but the location and a few conversations about the journey and team convinced me this was the right role for me.

I was leaving a role and company I loved and jumping into an exciting unknown, however the role was fantastic and everything I had done before had led to the perfect timing of this becoming available.

I have now been here four months.  Initially working hard creating a sense of teamwork as the team themselves are virtual, based across five Countries and six timezones.

The team is split across five distinct areas –


So can Tableau change your life?  Absolutely.  For me, it has been career changing, improved my salary and provided opportunities that I could only dream of when I started out pushing trolleys.  I have made some great lifelong friends and really enjoy getting out of bed and going to work in the morning.

If you want to grow into a larger role or spread your wings, now is the time.  Look at all the things you currently do in your role which you or your leadership sees as ‘business as usual’, and step back to think about how other companies would bite your arm off to implement them.  Think about your Tableau and BI journey and where you are compared to most other companies.

To help yourself, work on your public profile.  Write a blog.  Present at conferences.  Build a great supportive network.  Become involved in your local user groups.  Learn the tools. Articulate the best practices you are using without compromising proprietary information. Be innovative with your CV and confident in your abilities.

Over the next few years, more and more companies are going to be looking for people like you to build and delivery their BI propositions.  Take a look at the skills gap the Data School is current filling, then realise Tableau really can change your life too.



Taking notes at the Tableau conference

There are several trains of thought on taking notes at conference, from one end of the spectrum of taking none at all and just enjoying the experience and sessions to the other side of the scale where your employer only signed off on your trip if you promised to capture word for word everything that was said, to categorise and rate its relevance to your business and in the process include pictures of each session as well.

If you are lucky enough to fall into the former category, you can stop reading here, go ahead and really enjoy the conference.

However if you are the later, hopefully the following will help you out.

Now the second example I gave might sound far fetched, but actually, it is a situation I found myself in at my previous employer.  I remember sitting in the front row in Seattle in 2014 with Andy Kriebel next to me, astounded that I had my laptop out with a preconfigured template for every session that I attended.

You may have already gone 10 rounds with your boss or the CFO in justifying the trip in the first place.  Tableau do their best to support this by providing a template on the conference website to help rationalise the trip

Tableau justification letter

However if we are being honest, if the conference was in Nebraska (apologies to anyone from Nebraska) we would have a much easier job getting sign off than Vegas –

sure you are going to work hard for 15 hours every day in the party capital of the world!

So some of you would have gone into battle and won – you are going to Conference, however only if you are bringing back the notes as above.

This was the template I pulled together for Washington – my first conference.  This was the third or fourth version as well that I had to agree with my boss, to cover off how applicable it was to business delivery, IT delivery and Tableau deployment.

Excuse the   RAG status, I was innocent to such things at the time.  But it was a great one pager.  It covered the date, presenter, their role and company.  It allowed me to provide a summary of the session and some background on the presenter and their organisation.  Finally, I had lots of room to provide my session commentary.

Conference template

Notice the detailed explanation of the RAG status I attributed as well :-O

Conference RAG status

This really helped when I got back.  I pulled together a large deck, created a pdf output as well and felt like I was able to justify the conference to the accountants.

It would include all the good things like –

  • An executive summary
  • Customer presentations
  • Contacts made
  • Keynote overview

Conference Summary 2013

Now as the years went on, I still had to do this, but the technology allowed me to get smarter with it.

Rather than having the laptop out, carrying the charger, plus chargers and bricks for the phone for pictures, I can now do it all from the phone.  Specifically, I use an iPhone but there must be the equivalent on Android as well.

I use the inbuilt Notes app.

Notes app

What is great about it is that I can do all the things I want to, take notes, use hashtags, take photos, create a commentary all within the app and on a single device.  However if I do want to use the laptop, I can and just carry on where I left off thanks to iCloud syncing.

When I started using notes, I actually used the Laptop to write and the iPhone for pictures, primarily to preserve battery, but as I have gone on I have now moved to a single device.


My general flow goes something like this –

Make a note of the session, speaker and any # / twitter handle used.  Take notes in the app as I go, and take pictures of the presentations (#protip always sit in the front row to get the best quality pictures without heads in the way) and insert those into the flow of the note.  I take the picture using the native camera app rather than within notes because it gives you access to things like HDR and saves a copy to the camera roll, which the notes app doesn’t do which is frustrating.  The HDR can be a godsend due to the naturally dark rooms for the presentations and especially the keynotes.

I also tend to do a copy of the hashtags, this allows me to multitask and tweet out at the same time rather than wasting time trying to type.

I can use markup to annotate the pictures and bold to highlight a keyword for search later.

Afterwards, if I am asked to present details back, it is simple to copy paste the whole content into Word for distribution.

At the top of each section, I write down any questions or follow ups I have.  This is handy as an aide memoir after and also to ask questions at the end of a session without trying to find them within what you have written.

If I was full on note taking pro – I would be able to do what the awesome Catherine Madden does, through graphic recording, or real time visual note taking.


She does run a course on it so maybe that should be on my to do list for 2018!

Everything you need to know to prepare for the Tableau Conference 2016 #data16


I know I know, there are already several posts about this, but you can never have too much advice and experience shared can you?

The conference this year is in Austin, Texas and takes place between November 7th and 10th.  It will be bigger and better than ever, with over 15,000 customers, employees, partners and sponsors attending.

However thinking about the upcoming conference takes me back to where my first blog post started

Destination data

I know it is hard to believe, but back then I was not the social butterfly I have blossomed into but was very shy and nervous and knew practically nobody at the Conference.

In fact, the people I knew I could place on one hand –

  • Tom Brown, purchasing licences through him
  • Andy Cotgreave – met him once at a Tableau event and asked him to demo plotting paths (which he did)
  • Peter Gilks & Carl Allchin (Met them once at a Stephen Few workshop)

Sitting in the bar at the Conference venue in Washington about to have some dinner and  tweeting this picture (I was knew to Twitter as well!)

Only to find out that I was not alone –

Susan came and joined me and we had a good chat.

Then Andy Cotgreave and Tom Brown  joined as well.  I wasn’t too sure who the next person was but it was a young and enthusiastic Brit named Matt Francis!  He was very excited about the other people to join us which included Tableau Zen Masters (Tableau what?) namely Chuck Hooper and Craig Bloodworth.

I was no longer alone at a Tableau Conference.

The point of this intro, is that all of us, at some time, have discovered Tableau and its community.  Either at user groups, roadshows, via Twitter.  We would have seen or heard of people but never met them and potentially never had contact with them.  We could be in a position where we have persuaded our boss to buy a ticket for conference, but not for our colleague so we arrive on our own.

Once you arrive though, you are no longer alone.

Do not worry about reaching out to the community.  They generally do not bite and will seek you out if you write a similar tweet or invite you to join them on their table.  There is no hierarchy, no clicky in clubs, we are all passionate about Tableau and so are you, so that automatically makes you a member of the club.  If you currently follow someone on Twitter or their blogs, drop them a message and they will be happy to say hi.

Oh and a great tip from Chuck Hooper, make your social media avatars a proper head shot before the trip as it makes it a lot easier to work out who somebody is.  On that point, don’t worry if people come up to you and you have no idea who they are and have to look down at their name badge, it happens all the time and the subtlety which people look down has evolved into an art form.

Once you meet people though, that is only half the battle.  How on earth do you plan for all of the sessions?  Which to attend, when to see the Tableau Doctor, how to meet up with people you met at the bar last night?

Hopefully the following should help you with this.

For a few years, Matt Francis and Emily Kund ran a newbie session before the conference started in anger.  This was great for helping people orientate themselves and pick up hints and tips.  This year that session is being run by Tableau on Monday (see below)

Before you leave home

Ok so before you head to the conference, work with your network or send a tweet to find out who is on your plane or arriving at the same time.  This can be useful for sharing a taxi and reducing costs.  My flight is BA191  from Heathrow to Austin, arriving at 5pm local on Saturday 5th November and there is about 15 attendees on that flight, so arranging a car share will be fine.  Let us know if you are on the flight at well.

Pack clothing that you feel comfortable wearing.  You will be in these clothes for a long time during the day, potentially 12-18hrs, so think about that including your choice of shoes.  If you have any Tableau t-shirts, bring them along, always a good conversation starter when wearing the same t-shirt as somebody else, especially when you have got them for a particular competition.

Download the conference app, which will be available for Android and Apple.  Use this to book in your sessions (you can change these at any time) and plan using the floor maps where sessions are (more on this later).  I generally go to sessions based on the speaker rather than the title, as I feel I know somebody’s work in the community from Twitter or their blogs and know that I will learn something or understand who are already good presenters.

If you are arriving on the Saturday or Sunday, there will be time to do some sightseeing activities.  Plan ahead and book these in advance, including travel.  See what others are doing as you might be able to join a group and save costs.

Plan what technology you will need during the day and pack appropriate chargers for this.  Are you the kind of person that takes notes?  In my previous role, I had to take a lot of notes like this for each session


If you are bringing your laptop, ensure you have adequate power.  Mobile / tablets, bring cables and power bricks a plenty.

Make sure you let the Community know you are coming.  There are several hashtags you can use, the main event one will be #data16, some will use #tc16 or even the legacy #tcc16.  To help, save this as a shortcut to save typing each time you tweet.

If you have friends going along, set up a Whatsapp group, this worked great last year for keeping in touch, arranging to meet up and keeps the mobile charges down.

Arriving in Austin

If not from the US then TURN OFF YOUR DATA!  I had a terribly nasty surprise a few years ago, and even last year when I thought I was on Wifi I ran up a bill of over £1,500 which I had to negotiate with my provider on.  To be sure, turn it off.

Once at the hotel and unpacked, work out your plans for that day / evening and arrange a meet up.

Work out the logistics from your hotel to the conference venue.  Is there a decent Coffee house en route?

Double check any activities you have booked and the relevant transport.

On the Sunday afternoon, registration opens at 4pm.  If you are in town, this is a good point to register at it can get crazy busy on the Monday.  This is also a good time to meet up with other people, chat in the queue etc.

It is also an opportunity to walk the halls.  By this I mean look at some of the key sessions you want to attend, then walk from the previous session room to the next.  How long does it take?  Remember that you are doing this on a Sunday in an empty venue.  Come Tuesday, there will be 15,000 other people doing the same so add a lot onto this.  Also remember that this year the conference will be spread across several hotels so you may have to leave the building you are in.

Tableau map.png

Also scope out where the Expo hall is.  On the Sunday this probably won’t be set up, but if it is take a look and definitely book in a few hours to really look around the Expo.  When doing so, think about what could help your Tableau deployment and concentrate on these first.  Also, this is where the Tableau shop is to purchase T-shirts etc, but they sell out of things fast so shop early.

MONDAY Pre-Conference

This is the day for training, potentially exams, registration (if you didn’t on the Sunday) and a few other cool events.  The Tableau Hackathon is on all day and this year will cover all data platforms #DataDev.

There will also be a live #makeovermonday #data16MakeoverMonday, hosted by Andy Kriebel and Andy Cotgreave, well worth attending.

The Intro to TC16 for Conference Newbies is being run this year by Tableau’s own Vanessa Au, details here and is repeated in case you cannot make either session.  Follow the hashtag #TCNewbie for all the tips

This year also see’s the third Annual Data + Women event #DataPlusWomen

Monday evening will consist of informal events, potentially meeting up with your Tableau representative or partners for dinner.

Monday Morning also has the first #RunData16 event, starting at 5:30am and with two distances available – 5k and 10k, come and meet in the reception at the Four Seasons and get to meet members of the community (and me!).  If you are interested in taking part, join our group on Strava

Over 100 of us #rundata15 in Las Vegas

The most important activity you can take part in though is to have your #picwiththepauls

A annual highlight of the conference with a bit of a twist this year as well.

Tuesday – Thursday

This is the real meat and bones of the Conference, with over 500+ sessions which are broken down into a few sections

  1. KEYNOTES – Attend all of these to gain product insight, learn from industry leaders and be engaged with entertaining presentations
  2. BREAKOUT SESSIONS – Generally 60 minute long presentations by Customers, partners, Zen Masters and Tableau themselves.
  3. HANDS ON TRAINING – Normally two hours long, in front of a screen led by Tableau experts and trainers (pre registration is recommended)

For these days you really need to be prepared.  These will be long days so comfortable clothing is a must.  Ensure all of your tech is charged, and you have power bricks and cables where necessary.  Put your phone on low power mode where possible to preserve battery (unless you are using it for notes / pictures / twitter).

You will need fuel, so stock up where you can.  Save things from Breakfast, have spare water and in between sessions there are food stations available (Bits and bytes), but you may struggle for time to get to these.

Plan your day by the hour, starting at 7am (5:30am if taking part in #rundata16), work out breakfast, travel time, sessions, snacking, lunch, dinner, evening activities.  Do not expect to see everything that you plan to.  Historically I would say if you achieve 70% and you are doing well.

Lunch can get very busy.  The food stations will be repeated across the halls, so don’t just jump in line in the first queue as you enter a building.  Walk around and you will probably find a shorter one available around the corner.  Plan in your first session after lunch as well and give yourself plenty of time to get there, some people will pick up their food and take it to eat in the queue to get into the next session.

This brings me to a point about sessions.  You will spend a lot of time working out which sessions you want to attend and be proud of your selections.  You will then go to a session to discover that the room is full and you cannot get in!  This caught me out before, so always have a plan B for every session.  Where possible, make that plan B close by otherwise you may find that full as well.  This is where registering on the App really helps.

Tableau look at the interest in each session and can then change the room size / location to accommodate, this is great, but can also lead to you arriving at a room which has subsequently been changed, so keep an eye on this.  To help your app update, close the app fully every now and again to ensure that it sync’s up with the updated schedules.

If you need a comfort break in between sessions, get to the session, check in and drop a bag on a chair, then go to the toilet.

When in sessions, always sit at the front.  Don’t be shy.  You will be able to see the screens much better, they do vary in size and quality from room to room.  Also if you are sitting at the front you can take better pictures if you want to capture key points.  The other thing to do is ask questions.  Nothing worse than being a presenter and having tumbleweeds at the end of a session, so be bold and speak up.

The other thing to do, which a lot of people shy away from, is walking out of a session.  Trust me, you will want to do this at least once.  You select the sessions based on the speaker / content / title/ company, however you have no idea how good the session will be.  If it is not what you expected, walk out and go to another session.  Your time at conference is precious, and you do not have the luxury of giving somebody an hour of your time.  The speaker will not even notice so do not feel that you will upset them.  Do what is right for you.  If you talk to Andy Kriebel he will tell you that this is the most important thing he recommends you do at conference.

If you have a session you want to get to, don’t worry about leaving during the Q&A part to give yourself extra time.

Remember as well that if you really want to see two sessions which clash, they are all recorded.  So make time after the conference to watch back those that you couldn’t see live, or heard others talking about.

When you have been in a session, provide feedback on the app, this really helps future content and speakers to understand what they did well and could improve for the future.


Over the years I have seen some various note taking techniques.  You can see the template I have had to use in the past.

These days I use the generic Apple Notes app on my Macbook, whilst taking pictures with the iPhone which automatically sync across.  This also allows me to cut and paste into live tweets and multitask.

#sketchnoting is also on the increase.  I first saw this by the amazing @catmule who is a real artist, however I have tried it a few times with rubbish results, so more practice needed!


Post Conference

There are no two ways to put this, after the conference you will feel on a real downer.  Spending a week with like minded people and learning new things is amazing.  The day job seems boring by comparison.  But keep the spirit alive.  Blog about your experience, share what you learned with your colleagues and most importantly share with your boss what your key takeaways are and how it will change what you do.  This can help not just yourself, but your colleagues when looking at budget for #data17 when we all return to ***** 😆

Vizable on the iPhone

For anyone that know’s me, they know that I am an advocate of Vizable, the app which Tableau and Dave Story launched in Vegas at the #data15 conference last year.

It was the fruit of their work on project elastic and really excited me.

I use Vizable almost every day.  Wherever I see a pivot table or an ‘Excel Database’, I introduce and usually convert the user to Vizable.

One thing I have been waiting for and tried numerous hacks to work has been to get it working on the iPhone, the product I have on my person and in my pocket ALL of the time.

I use an iPhone 6S Plus, which has a large screen real estate perfect for Vizable.

So when I had a call with Trina Chaisson, the Vizable product manager and co-founder of Infoactive and she said what was about to land in the App store I got very excited.


In fact when it landed in the App store – I managed to tweet about it before even Tableau or Vizable were able to make the announcement – sorry guys!!

app store

Here is how in 90 seconds I  go from my home screen to having it installed and analysing data (Best watched in HD and fullscreen mode)

As you can see it is very simple to download and intuitive to use.

To get started, I thought I would explore one of the recommended data sets and download my Amazon shopping history.

Now if you use the US Amazon store, this is really easy to use by following these steps –

amazon recipe.png

However if like me, you are in the UK, it is not so simple as the order reports are not able to be downloaded.

Fortunately, if you use Chrome, there is a workaround which I found on the forum.

Here is the app

And what the data looks like

Now I can import into Vizable and start to explore my data.

First I explored my orders by year – I am definitely using Amazon more each year (2016 is only part year)IMG_3890

I have been an Amazon prime member for a few years, does it pay for itself?


What are the products I repeat purchase the most?  Interesting that the Baby Wipe I have on a monthly delivery seem to change provider and description on a regular basis.  I would have to clean this up better to get the full picture.


Are all of the items for me or do I send a lot of gifts?  It seams that I send a lot to @infolabUK ‘s own @_tombrown_  – or this may be skewed by a gift to say thank you 😀


Finally I wanted to understand if my average postage costs had really come down through the use of Prime or was I still ordering products which were not eligable for the Prime service?  It certainly appears that I paid more high price delivery charges in 2015 with a maximum of £7.99 and have seen a 4.4% increase in the average shipping costs from when I started in 2010


So very quickly I have been able to see, touch and understand my data and hopefully you will all try this as well.

How can you make Tableau server project folders more interesting?

With the introduction of Tableau 9, you had the ability to control the descriptions on the project folders and add some basic formatting.

Initially though, I was very disappointed with the feature as it seemed to make the folders look like large empty spaces.

Boring folders

You can see in the default folder, that the text has been changed, but who want’s to look at all of that white space and the grey image of a file?

I thought that there had to be a better way.

At first, we added text to explain what the folder was and looked at the basic editing functions available –

Commercial server format

We can see at the bottom the ability to use basic HTML formatting, but as with a few things in Tableau, it is the undocumented things which really add value.

For example, through adding the <img src/> code, we can add a picture, to make the folder more colourful, in the example below this is as simple as putting in a footer.

What about putting in a picture of a report in the project though, to show the end user an example of the content.  That works as well, brightening up the default folder.

But how about taking it a step further.  If <img src/> works for an image, can I make it work for a .gif to allow me to run a carousel of the content within the folder?





Well that looks a lot better and is more intuitive for the end user.


So what are the steps you need to follow to do this?

  1. You need to have admin access to the box where server is located
  2. Create a .gif (I use by using some screen shots of reports in the project
  3. On the server, go to this location and save the .gif                                                                                                                                                                                                                                                     Gif location                                                                                                                                                                               It doesn’t matter where your Tableau server files are saved, as long as it goes into the htdocs folder
  4. On the server web portal, edit the project description within the details tab                                                                                                                                                                                                       Commercial server preview
  5. Type in the following code – <img src=”filename.gif” width=”448″ align=”middle” /> Replace filename with the name you gave the .gif.  As long as it is stored in the htdocs folder you do not need to put the full path
  6. Click save and it should be working a treat


If after this, you only see a static image, your browser settings are probably restricting activeX controls.



The finished work should look like this






Introduction to Data visualisation

Internally at work, I run a monthly workshop introducing people to data visualisation and explaining why it is important and how we use Tableau as our tool of choice in this area.

The workshop was initially aimed at the analyst community, but as the months have gone on and the popularity of Tableau increases, I am seeing a wide variety of people attending, from our Board, to managers to people who just use Excel but want to do things better.

The workshop lasts about 90 minutes and is mostly in Prezi, before I move into showing some Tableau demonstrations and our Facebook at work pages, where people can download our colour palettes and understand some of the choices we have made.

So far, about 130 people at work have seen this and along with a few members of my team, I am writing a follow up session.

Obviously, I have not created all of this content from scratch.  A few years ago, I was lucky enough to attend Stephen Few’s three day workshop in London, based around his books at the time.  It was at this event where I first met Tableau community legends Peter Gilks and Carl Allchin.

I took my leanings from that, and converted his three books and several hundred pages into a 30 page PDF that people could use as a reference.

Following this, I also attended Andy Kirk’s workshop and have several data visualisation books in our internal library including Alberto Cairo’s book the functional art, all of which I have tried to take examples from to improve our internal guidelines and best practices.

Data viz books

At the Tableau conference in Vegas #data15, I mentioned this workshop and touched on a small part of it.  A few people in the Twitter community sent me messages and asked if I would share it.  As it was internally branded, I didn’t want to do this on a wide scale level, so thought that I would create a ‘public’ version and publish it here.

The Prezi should allow you to follow through the journey, which is based around transforming information into insight.  It obviously works better when I am present to talk through it and the examples, but hopefully it gives enough of an introduction and I am happy to talk about it in more detail or come and present it.

I will follow this post up with some details on setting your colour palettes as well as how you can put standards in place for your Tableau dashboards.

How to prepare people for a live Tableau Viz Safety demonstration

Ok so we are all back from the Tableau Conference which was amazing and I need to complete my post on that later today.

In the meantime, I thought I would share this video excert from my #data15 presentation.

It is 90 seconds long and shows the lengths that we go to when preparing to show Live Tableau demonstrations.

Watch out for Tom supporting the demonstration in the aisle and also my sincere apologies to the Lady just in front of Tom whose reaction is priceless (If anyone knows who she is I will send her an apologetic goody bag in the post!)

I hope you enjoy this – turn the sound up 😀

Virgin Atlantic Flight VS43 landing gear problems – updated

In December 2014, Virgin flight VS43 from London Gatwick to Las Vegas encountered a hydraulic failure on take off.  I built a viz to show the path that the aircraft took, its holding pattern and impact on Gatwick operations specifically for easyJet.

The Air Accident Investigation Branch have just published their findings into the incident AAIB VS43 investigation and as quite a few of the UK Tableau community, including a large chunk of the Information Lab are about to fly out to the Tableau Conference #data15 in Vegas on this very flight, I thought it was a good time to revisit and improve the viz based on some feedback I got at the time, specifically from Andy Kriebel and Ben Jones.

Enhancements I have made include –

  • Using the storypoints formatting tools in 9 to change the story colours to match the corporate colours of Virgin Atlantic (the colour picker tool is fantastic for this)
  • Included some photographs of the aircraft, as well as the landing gear problem it had
  • Made the maps consistent which I used across the whole viz
  • Condensed the story points descriptions
  • Fixed a colour issue which was bugging me for the easyJet paths
  • Updated the annotations with the details from the actual AAIB investigation
  • Included a link to the final AAIB report
  • Utilised the increased number of rows in Tableau Public to 10m rows to allow me to include every Gatwick flight for the day to be followed
  • Tidied up the last storypoint where you can follow the aircraft on its journey, making the pages slider more applicable – this is still best viewed on Desktop with the full pages functionality.

Hopefully we will have a great and uneventful flight out this weekend.

Looking forward to seeing a lot of you at conference and don’t forget to come and see my presentation on Wednesday at 10:15am #easyjetdata
