The majority of the work in this project was taken directly from MaximPorges.com article on Scrolling Large Data Sets in Flex Charts. The code posted in that article works very well for horizontal scrolling, but not at all for vertical scrolling. Several commenters on that page have posted needing vertical scrolling, and at least one noted that they'd made a fix. I was unable to find their fix, so I made my own.
Below is a Flex Builder 3 project zip that includes my changes. This code works well for both vertical and horizontal scrolling, as a custom Chart Axis Renderer. Use the links below to see the working example, and the source code.
