Using Images in Tableau

Posted by on Aug 21, 2014

There are several ways to add images to your Tableau reports, some more obvious than others, in this blog post I take a look at the options and explore their advantages and disadvantages and look at some examples of where I have used them in my own visualisations. 1. Using Tableau “Shape” marks Overview: You can upload the photos into the \My Tableau Repository\Shapes folder (either into an existing folder or into a new one) and then display them on worksheets as marks. This is flexible in terms of usage and allows filtering, etc. However the system can be difficult to manage for...

Help – my blending isn’t working! When Orange is the new Grey

Posted by on Aug 11, 2014

Data blending is a really powerful feature of Tableau, allowing you to bring together information from two completely different places, such as a centrally managed database and an excel file on your desktop. It also allows that data to be brought together at different levels of aggregation, such as if one is daily values and the other is monthly targets. However, sometimes the blend just doesn’t seem to work, and trying to identify what is going wrong can be tricky if you can’t see what’s happening. This post is going to focus on one of those times. And yes, as those amongst you may have...

I’ve been speaking to a lot of new Tableau users in client organisations recently, and I hear a lot of feedback from first-time Tableau users along the lines of, “My boss needs this report by Friday, I don’t have time to learn a new tool”, or “This is for IT, I don’t understand this”, or “How quickly can I recreate my Excel report in this?” ….I could go on, but you get the picture.

Tableau Server housekeeping made easy

Posted by on Jul 25, 2014

The best thing about administering Tableau Server is its self-sufficiency – the server manages its memory pretty well, processes that die are automatically respawned, and monitoring tools are already built-in via the administration dashboards. While this is all good stuff, Tableau Server does require a bit of housekeeping to keep the server clean, secure and backed up. Left on its own, a Tableau Server will quickly accumulate hundreds of MB in log files and leave your install at risk with no automatic backup processes in place. In this article I’ll show you a handy script and some...
