Hi, 
  
I am trying PowerCharts XT (v3.2.1) (Released on 30th July 2012). 
Everything is OK, but looks like link attribute of set element is not working. 
I tried to set link in demo HeatMap1.xml (<set rowId='Google' columnId='MON' value='80.456' link='http://google.com' />) - is not working. 
According to documentation links are supported by HeatMap. 
Did I forget smth ? 
  
Regards, 
Andrey
