Question

I have some specific requirements, with the most important at the top:

• Can plot line and stacked bar charts
• Can customize mouse events (hover, click) on chart data
• Compatible and performant with IE7/8 (likely will use excanvas.js)
• Can optionally control label formats, legends, colors
• Open source preferred, or at least can purchase the source
• Can be hosted locally

I have seen a couple potentially good ones:

• Google’s interactive charts (But code must be accessed via Google servers)
• EJSChart
• Flot

Does anyone have experience with these, or others, and can make a recommendation?

Answer 1

We have used http://www.anychart.com/home
in our recent project.
It is based on flash but you can easily work with it via generating xml.

But one very big problem – generate image from flash is very difficult.

Also i know that MS have their charts(free) – code.msdn.microsoft.com/mschart
