Last week, I had the opportunity to attend the Alteryx Inspire 2014 conference in San Diego. The show was well-presented by Alteryx and conveyed a very consistent message of “data for the people.” I’ve attended many conferences over the past 25 years, and I have to...

There are people living in America today who did not have electricity in their home growing up. It cannot be overstated how much the power industry has changed since then. To understand and communicate those shifts, we turn to data. Some have done an outstanding...

So many times in history one person's valuable contribution ends up being eclipsed by another for no good or fair reason. Think of Galileo, who was not (and never claimed to be) the inventor of the refracting telescope - it was invented by Dutch spectacle makers....

Most data analysis is concerned with understanding what the data tells us - for example understanding if business is growing or not and discovering how sales are developing in different territories or across product lines. But sometimes the story the data is not telling can be...

Do I have a healthy pipeline of sales opportunities? Ensuring a healthy pipeline of opportunities is a key concern of any Sales Manager. In this post I would like to share with you a way of visualizing your pipeline that has proven highly valuable in practice....

In Part 3 we created all the calculated fields necessary for our basic Mekko. Because we have preset the DTC (Direction of Table Calculation) for each calculated field we can simply drag them on to the view to create the mekko and be confident that the values...

In Part 4 of the blog we learned how to make a basic Mekko Chart. In this part of the blog we are going to add in some totals, thankfully we can use some of our existing calculations to do this. The first is the...

Before we can attempt a Marimekko, we need to understand a few of Tableau's lesser used tools. The first of these is the Polygon mark type which can be selected from the dropdown on the marks card. Since the Marimekko is actually made up of lots...

In Part 1 we learned how to use custom SQL to shape our data ready for use later on in polygons. In this part we will use parameters to allow dashboard viewers to exchange dimensions. This methodology can be applied to any chart type which is sliced...

In Part 2 we simulated a Marimekko using stacked bars but since the boundary for each element / polygon of a Marimekko in Tableau is made up from 4 Cartesian Coordinates we are going to use scales of 0 – 100 % for both X and Y...

Tableau has the ability to recreate any colour by using the RGB colour model. By using this you can customise your charts and dashboards to match your corporate branding guidelines. The chart below shows the top 5 BBC Television Channels by expenditure in 2012. It is...

This Marimekko chart was fun to get right. There are some great examples of complex table calculations built in to it. The use case is similar to that of a series of stacked bars. It has graphical similarities to a treemap but it lacks the...

The Tableau Customer Conference 2013 turned out to be a truly inspiring event. Hans Rosling captured the hearts and minds of the packed event room as did Andy Kriebel (Facebook), JP Rangaswami (Salesforce), Tableau’s own Christian Chabot and many customer speakers such as Cisco’s Rob...
