UltraPieChart UltraItemLegend only shows "DataItem" for text
posted

I had this working at one point and now I've messed it up and can't get it working again. I am showing a simple pie chart. The only thing not working is all the legend texts are showing as "DataItem" instead of the values it should. in my case "Assigned", "Rejected", etc.
