Using the winforms version I was able to achieve this by creating my own renderer and overriding the hit-test behavior. Is there a way to do something similar in the WPF version?
Also semi-related... in the pie chart I am using the selection to get notification that the user clicks on a data point, and then take some action. Usually it involves redrawing the chart and that all works fine. However when I don't redraw the chart, the datapoint is altered visually. Is there some way to "cancel" the selection in that case, or at least control how the datapoint is visually affected when selected?
Also (sorry things keep coming to me), I like the hovermode "FadeOtherItems" over look, but I feel that the amount that everything is faded is too great. Is there a way to control that?
