Extending plot types - adding a CIE 1931 type diagram

Show all headers | View raw

Hello guys,

I would like to extends Gnuplot with the ability to generate a CIE1931 digram of color spectrum, basically looking like this one:

http://commons.wikimedia.org/wiki/File:CIExy1931.svg

This kind of generator is already present in netpbm package as ppmcie.

I would like Gnuplot to be able to provide this background for the plot, so one could easily plot curves over this background directly with 'plot' command, withou the need of fitting the background to the actual plot.

So the task would be:
1. generate the background color image with the right coordinates, so that
2. plot points and curves into that plot as usual, taking advance of the coordinate system of the CIE x-y diagram

Thanks in advance for ideas,
Martin
