I'm trying to use one of the charts in my asp.net page and I have this simple code: 
  
  
  
 
  
  
  
Whenever I load up the page and toggle the visibility all I get is the word "Chart".  Any idea why?  Also, if I use RenderChartHTML I get "No data to display". 
  
Also it doesn't even work if I use the default Data.xml that comes with the charts...so I know it's not that.   
  
  
  
EDIT: I got it working.   
  
  
  
This line: 
  
  
  
 
  
  
  
Should read: 
  
  
  
  
  
 
  
  
  
As Data.xml is a url not a direct xml string.
