As a followup to my previous post showing how to write a custom renderer that used the underlying chart data, I 
thought I’d post a slightly more complicated example of how to extend the built in Charting Series types to add more advanced functionality. So go take a look at the Variable Radius Pie Series, then come back here and let me know what you think.

very pretty… now make it animate continuously, and I can stop clicking the button a hundred times :)

Very cool. There aren’t enough chart tutorials out there. I still want to create new charts and I have really no idea where to begin. Can you throw up a small example of a custom renderer that ISN’T based on another renderer?
I’m trying to create charts that wow the appropriate people inside my Fortune 50 (yes, fifty) employer, and I need to find ways to really impress them - they’ll want to see things like google finance’s chart to be truly impressed, I think.
Can you do something like that?

Very nice execution. I really see this chart getting popular and extended.

I get an error.
TypeError: Error #1009: Cannot access a property or method of a null object reference.

Hi,
I have never seen an example of the doughnut chart with multiple series, so it has multiple rings. Is this possible with the PieChart?
