Seems like the RadChart doesn't like my objectdatasource. Here's an update:
1.) Your stand-alone project works just fine.
2.) Ripping your chart code and placing it in my page with the other charts that don't work properly, works fine.
3.) Taking your chart example and giving it a datasourceid of my objectdatasource is problematic. It does not show the formatted $ properly.
My objectdatasource pulls back a datatable. The query behind it does a sum() of a float column in SQL Server.
Keep in mind, the designer shows the correct currency format. However, at runtime I'm getting one long string of digits.
P.S - my dollar amounts are in the millions...
