David,
thank you, your hint helped me to get a bit further.
See the screenshot, I was able to hide this zero
labels with:
function beforeDrawDataPointLabel(dph, label, icsc){
if (dph.getOrthogonalValue() == 0)
label.setVisible(false);
}
It seems that renderer thinks that these lines are still there,
when it calculates the circle diameter. Therefore the chart
is small. Can I somehow tell it to recalculate the circle diameter?

No, but you could try the opposite: hide the labels by default in the chart
model and make the non-zero ones visible at run-time. Not sure it will work,
but worth a try..
Otherwise try to download the latest weekly build to see if the problem is
still there, I think we already fixed some layout problems with pie labels
and pie size becoming small.
