Adding overlays to existing graphs

Sep 2, 2010 at 10:29 AM

I have a line graph plotted using GraphPlotter and RawDataSource. I would like to add some overlays on top of it (to indicate points of interest) based on metadata associated with plotted data. Is there a way to do it? If yes what is the best approach? I want to mark some areas on my graph (with a colorful and transparent overlay) and/or  add dashed vertical lines to it... is it possible?

Have you looked at the LineSample example - it shows how to add various things to a chart. While it adds them using XAML you could just as easily do it using code

Thanks that sample actually shows how to implement overlays as I want them!
