I have a line graph with about 300 datapoints on it. So to smooth it out we have changed the ShowPointMarks property on the
to be false. This works great and makes for a really pretty chart. However I also need to be able to click the point to display data in a textblock (got this working by adding a handler for the DefaultView.ChartArea.ChartItemClick) but what I want to now is change the style of the chart item that was clicked to show a point mark to tie the visual point on the graph to the extra data I am displaying in the textblock.
Is this possible?
