A feature that we are being asked for is the ability to select a bar component from a bar chart that enables the user to click through to another report, change other data displays, etc. This is a common feature we see on Microsoft Reporting Services, Silverlight, and other reporting tools we come across. I believe some of these features are available on the pie chart tool, but not on the bar chart. I can write some of my own logic to do this using the mouse on-click event and the x-y coordinates compared to my dataset, but I think there could be a cleaner way to do this. Thoughts?
Maybe you could pick up the colour of the bar the user clicks on, as per this post.
You could use a classic chart instead, use a bar renderer, and the classic chart allows for series selection.
