Over at Flowing Data, Nathan Yau sent out the challenge to visualize the Pew Research Center data about how people get their news. There are many excellent examples created that can be seen over in the Flowing Data comments (some very different, some improving...
As your Tableau Software dashboards become more complex you’ll often find yourself needing to mesh multiple data sets from two or more sources. One limitation this creates is the inability to define global filters to control all worksheets throughout your workbook. While actions can be...
Tableau provides many types of filter including range filters for dates and numerical data, but what of textual dimensions? For instance lets say we have a dimension with data in the following format, 3-digit months with a 2-digit year and a period used by the...

Flowing data posted nice and clear instructions on how to make bubble charts using R. It's a great post, and I thought it would be a good thing to show how to create the same chart in Tableau. Readers can compare and contrast the ease...

You may have seen my response to an Information is Beautiful post. Here's the viz I used in that post: Wikipedia banner testsThe effectiveness of donation appeals on Wikipedia Powered by Tableau This uses sheet tabs to create an "About this viz" tab. It is good practise...
Those of you who follow me on twitter (@acotgreave) will probably know that most Fridays I get involved in the rathe excellent FridayMix. This week it reaches its first birthday. I downloaded the full list of all 3500+ tracks that have appeared on a FridayMix...
Following the budget cuts announced yesterday by George Osbourne I, like I'm sure many of you, have been trying to get to grips with what these cuts will mean for the country going forward. Clicking through some of the reaction on the BBC new website...

Warning! This post discusses disc golf. If you’ve not heard of it, just imagine I’m referring to “normal” golf. The US Disc Golf Championships, the world’s toughest, and richest event is happening this week. The leaderboard's on the PDGA.com, and on the USDGC sites are ok,...
There’s a chart doing the rounds that shows who is suing whom in the telecoms industries (eg at the Guardian). David McCandelish has improved it nicely here, and asked the question of whether companies who’s revenue is going down are more litigious than those on...

Tooltips are the missing link between a mark and its underlying data. They provide a valuable opportunity to explain more about the chart without requiring the user to examine the underlying data. The motivation for these posts was seeing so many vizzes on great charts on...
