Resize Pie Chart based on optional grouping count

JasonW

This report resizes the chart based on the number of optional groups (individual pie charts). When using optional grouping a new dataset is created automatically, so we can use the the afterdataset event to count the number of groups that get created. After all the data is processed the beforeGeneration event is fired and we can change the size of the chart. Look at these two scripts in the example.
