Interactivity between charts?

[Douglas]

I am trying to get this scenario working:

1. I have 2 charts and a DataGrid
2. Chart 1 is a 100 stacked bar chart
3. Chart 2 is a pie chart
4. When the user clicks on a bar in chart 1 I want to update chart 2 to show the stacked series in the pie chart.  In addition I want to update the DataGrid.

What would be a method of doing something like this?

I found the ItemClick event handler and that seems to give me a way to do something.
