This is a fairly straightforward topic but I did a quick DZone article on charting with Flex and PHP using the data-centric design wizards in Flash Builder. The wizards make it very easy to at least get the basics down and start using data in charts, and I covered some basic ways to add animations and interactivity.

I’m working on a more in-depth article with Zend that will cover grouping/sorting/etc on both the client and server side. It will provide some info on how to structure your data and make it more flexible for manipulating when it’s in the chart.
