I have to draw 3D pie chart in ipad using core-plot API .how can i do it ? Please advise .

回答1:

Core Plot is 2-D only. You can create simulated 3-D effects on pie charts using shadows and/or an overlay fill. See the Plot Gallery example app for some samples.

Have a look at the BNPieChart. It is a openSouce.
Code Sample

BNPieChart *chart = [[[BNPieChart alloc] initWithFrame:frame] autorelease];
[chart addSlicePortion:0.1 withName:@"Orange"];
[chart addSlicePortion:0.2 withName:@"Fandango"];
[chart addSlicePortion:0.1 withName:@"Blue"];
[chart addSlicePortion:0.1 withName:@"Cerulean"];
[chart addSlicePortion:0.3 withName:@"Green"];
[chart addSlicePortion:0.1 withName:@"Yellow"];
[chart addSlicePortion:0.1 withName:@"Pink"];
