All Visualforce pie charts I see online and the one's I'm developing now seem to just randomly place wedges on the chart. Update: the first wedge is placed with a horizontal center line pointing to 90º
What I'm after is some option to force starting at the same spot. I think "12 o'clock" is the most common one but anything will do. Compare with this example Google chart:
Any ideas? Couldn't find anything in the reference of <apex:chart>
or <apex:pieSeries>
and the generated Javascript looks scary (plus probably my change would break the moment someone starts interacting with it).
