How to do custom chart annotations in Flex
{ Posted on Mar 03 2009 by david }
Hunting around the ‘Net, I found a few good examples of creating chart annotations in Flex.
One example app which helped me greatly was from a blog posting by Ely Greenfield. If you’re interested, you can view it on his website: chart annotation demo.
Unfortunately, the code you can download from his site is a little old so it has problems compiling in Flex Builder 2+. I have updated the code, fixed some bugs in it and have it available here: download OverlayDemo-fixed.zip.
Ely has other interesting demos on his site which are worth checking out. Some of my favorites are: the variable radius pie chart demo, the interactive bubble chart demo, and the dashed lines demo.
