I just downloaded telerik charting (both asp.net or sliverlight version). It looks quite good.
Our current in-house charting tool allows us to add custom type. For example on a basic bar chart, we can put some arrows here and there.It is like add a new layer on top of the chart (bit like on Google map, I can add pins and markers etc.)
I am wondering if this kind of feature is supported (drawing random staff on top of chart), if not, is there a work around?
