Back!  After almost a year of working on things.  First - ChartDirector is functioning flawlessly.  :-)  The human programmer.....  :-P

Anyway, I had an idea.  Don't know if this is in ChartDirector or not so I'm just throwing it out there.  :-)

Idea: Non-circular pie charts.

What I mean is - instead of making a "pie" chart - draw straight lines between the various points on the circle.  So you might wind up with an octogram, pentagram, septagram, or something with even more sides to it.  It's just a variation to the pie chart.  I'm looking through the documentation to see if you can already do this but since it has been a year I thought I'd stop by and say hello in any event.  :-)

Hi Mark,

Thanks a lot for your valuable suggestion.

The idea seems easy to implement for 2D pie charts. However, it may be significantly more difficult in 3D, in particular that ChartDirector supports "Multi-Depth" pie charts, donut charts (with holes) with various 3D lighting effects.

In any case, we will take note of your suggestion and consider it in future versions of ChartDirector.

Regards
Peter Kwan

Sounds great!  :-)  I was thinking that if you just calculated the start angle and end angle and then did a triangle from the center to the other two points and back that that would be all you'd have to do in order to convert all of the pie chart algorithms to the wedge algorithm.  Thanks again for considering my idea.  :-)
