Chart Widget - piechart

Is there a way to combine multiple point features into one class/type, so that the piechart indicates the comined percentage?

In other words, I would like to select an area on the map and have the piechart combine all #2's, #4's, #6's and display a percentage for all like features instead of a percentage for each point selected.


I'm working with a feature file with hundreds of points and each point has a number between 1 and 10.

Thanks,
