Maths - Pie charts

[PhilBayley]

I am trying to create 3d pie charts and explode them as I need. Is anyone really good at maths or know a book that I could get to give me the algorithms that I will need.

 

I know c# has GDI functions to create pies and I can do the basics in this but I need to make it 3d and look brilliant.

 

Hope someone can help

Unless you have a lot of time to spend on this, I'd suggest using a 3rd party control. There are many graphing controls, most costing under $500 (small cost if buying for use in professional projects, very expensive if for personal use :)).

 

If you really want to do it yourself, be prepared to do a lot of planning on what features you want (exploding pie is a big feature, but a lot more code) and design it out first. You did say you wanted it to be brilliant, right?

Thanx Nerseus,

 

I am a pro developer and concidered the option of buying a third party product but we will get into big licensing costs when we distribute our product. The coding isnt a problem but finding the correct info to generate maths and graphics like that is a big part of writing the code. It looks like I will have to keep looking to the info I need.

 

Cheers

How so? I think you should have no problem finding a 3rd party charting vendor that has a royalty free distribution licensing structure. They wouldn't sell much if it were all on a per-seat basis.
