Markers, lines and other highlighting sign in the chart

Mar 28, 2013 at 2:48 PM
Hi,
I would like to know, whether there is a way how to add some markers specified by me (a mark of an arrow for example) and lines in the chart to highlight some aspects.

I added this simple image to illustrate what I mean - the red line with some text and the red arrow pointing somewhere.

Thanks for any tips.

I will try to make it with plotting the Silverlight elements, but if there is a better way, I would be interesting in it.
