Density maps are a great way to show concentration in an area. Let me show you how to create a density map in Tableau. Then we'll take it a step further to use hexbins as part of our density map.

Complex data can make these questions tough to answer even when you have distinct and well-separated groups. Plus the data is sometimes distributed in such a way that it contains no obvious gaps to distinguish groups via manual inspection. The good news: This process just got much easier in Tableau 10. The new clustering feature automatically groups together similar data points.

In the wake of the Brexit vote, many of us here at Tableau were interested in exploring the raw JSON data that was generated showing voting results by districts/unitary areas and Parliament constituencies.

And here we are, 26 weeks into Makeover Monday, a fun social data experiment that Andy Cotgreave and I have been running this year. What really surprised us is the way the community has engaged with us and with each other.

Andy Kriebel and I ran our first-ever live #MakeoverMonday at Tableau Conference On Tour in London last week. I had a great time, and if you’re heading to Austin for our US conference in November, you’ll be able to participate there!

I have been converting Tableau files from one version to another version quite frequently. So I decided to create a web-based conversion tool. This tool opens a TWB file in memory and loads the contents in a window, converts the version of Tableau, then saves a new TWB file.

Many of you have told us you’d like to create new geographic data using the data built into the geocoding database. And I am excited to announce you can do just that in Tableau 10 with our new custom territories!

I recently saw an article posted by Alberto Cairo in which someone had built a map of Scotland using tile maps built of Sankey diagrams. I thought it was pretty cool, so I wanted to be able to do something similar in Tableau.

I used to think iterating was overrated, always striving to produce the goods as soon as possible with as few tries as possible. That was until I started to participate in Makeover Monday, an initiative run by Andy Kriebel and Andy Cotgreave.

You already know that using visualizations to communicate data is fast, easy, and efficient (pictures are so much easier to interpret than a crosstab full of numbers!). But you might be wondering how to communicate with your data even faster. Let’s talk about data—specifically visualizing your data in a way that unveils insight faster.

I have no idea how long you've been able to do this, but it is something I recently figured out. For a long time, it has frustrated me that there is no "select/deselect all" button on the action dialogs in Tableau.

There is nothing worse than opening a report in an Excel spreadsheet and seeing pages and pages of columns that provide little or no insight into the data. But text tables do have their place, especially in the financial sector. Here are some things to consider when designing text tables.
