Draw a Pie Chart using quartz

[tharindufit]

Hi I want to draw a pie chart in my iPhone Application, I could do it using the following code I found in web
Drawing Pie Charts using iPhone SDK
Now I want to display text with the corner of the arcs, How can I do this with quartz, I want to get the points to draw my text on Pie Chart. How can I get exact points

You can easily draw strings at specified points by using drawAtPoint:withFont:

I think to determine the points you'll need to do some trig based on the size and position of your circle.

Sorry I could not mention it clearly, But I wanted to display my text around the pie chart, I can draw it below the chart. The issue is I could not get points to draw around the chart.
Thanks,

Right. You can draw your text wherever you like. If you want it to go to particular places related to the slices of your pie you need to use trigonometry to determine where those places are based on the center of the circle, the radius of the circle, and where the slices are.

Thanks a lot, Oh I could not think of such small thing, It's just some mathematics.
