Answer 1

This should do:

// Pie chart with radius of 100
$picture->drawPieGraph($DataSet->GetData(), $DataSet->GetDataDescription(), 150, 150, 100, PIE_PERCENTAGE);

// Pie chart with radius of 50
$picture->drawPieGraph($DataSet->GetData(), $DataSet->GetDataDescription(), 150, 150, 50, PIE_PERCENTAGE);
