hi,
I use a pie chart with optional grouping, and I want to rescale it according to the number of groups. I think i should use the function below. But I dont know how to get number of groups in the chart
function beforeGeneration( chart, icsc )
{
chart.getBlock().getBounds().setHeight(????*100);
}

Regards,
yassir.
