Re: [Plplot-general] Confused...

Hi,

by default only 16 colors are available. You need to change the number  
of colors in map0

http://plplot.sourceforge.net/docbook-manual/plplot-html-5.9.0/plscmap0n.html

Then it should be straight forwarded to set the colors in the map with

http://plplot.sourceforge.net/docbook-manual/plplot-html-5.9.0/plscmap0.html

HTH,
Werner
