We are working on a real solution to the general piechart problem.
So stay tuned, but don't hold your breath.

Note that gnuplot certainly is not the right program to add piecharts to it.

1. Looking for 3D PIE CHART/EXPLODING PIE CHART routines

I have requirements for a WWW-based information system
to generate 3D pie charts and exploding pie charts from
a UNIX Web server.

My system will be using IDL, which doesn't have any circle, ellipse, or
arc graphics primitives, so I need to work from lines, points, and regions.

The routine will be given an array of numbers and a list of labels for each
pie slice.  The output will be a pie chart, 3D pie, and/or exploding slices.
The image will be written to a GIF file and displayed via HTML document.

Has anybody written either an EXPLODING PIE CHART or 3D PIE CHART routines?
I've written a simple LOTUS 123-like pie chart routine, but I need
to find a more sophisticated one that produces Excel and Quattro Pro-like
charts.  Even some C code that can provide he same function would
be helpful, since I could convert it the IDL.

Any help would be appreciated.  Thanks in advance.
