Alteryx – The Enigma

Well that was a fantastic, inspiring and interesting Inspire 2015 – this year saw over 1000 attendees squeeze into the Westin in Copley Plaza, Boston for the Alteryx event of the year. The biggest conference so far saw the brightest and best Alteryx users battle it out on the Grand Prix stage, as well as seeing technical and business experts talk about how they use Alteryx day to day to talk about how they solve their business problems. Of course it’s not all about business problems though, and after Dean Stoecker highlighted the work of Alan Turing in cracking the Enigma Machine...

Show Me How: Scatter Plots

We have arrived to scatter plots within the Show Me How series. We will see how this chart type is created and used as well as some tips, tricks and pitfalls along the way. This graph type is commonly used to visualise correlation between two paired sets of numeric values, for example the sales value and profit content of sales instances.   Show Me Scatter Plots As always, Tableau’s Show Me panel is again a helpful guide for the building blocks of scatter plots. The starter scatter plot with two measures and no dimension practically draws a Cartesian coordinate system with an X...

We conducted a two part interview, each 15 minutes in length, all in quick succession… speed-dating meets The Apprentice! Each candidate went through a more traditional-type interview with Tom Brown and Jonathan MacDonald. Each candidate gave a demonstration of the analysis they did in Tableau to Robin Kennedy...

Show Me How: Dual Combination Charts

In this post in the Show Me How series we talk about dual combination charts. The name gives a good clue of what this graph type (or mark type as we call it in ‘Tableau language’) covers. ‘Dual’ means dual axis.

So a dual combination chart is one where there are two axes on the same pane and the measures are displayed in different mark types.   Show Me dual combination charts The common variant of...

Tableau and corporate analytical capabilities

In this post we divert from the daily, technical aspects of using Tableau and rather take a helicopter view to see Tableau’s connection to corporate, organisational analytical and decision making capabilities.   Self-service BI and Tableau Tableau is all about self-service BI and in their white paper they define it as “The facilities within the BI environment that enable BI users to become more self-reliant and less dependent on the IT organization. These facilities focus on four main objectives: easier access to source data for reporting and analysis, easier and improved...
