That should suffer, of course. It seems that I haven't figured out how
to set the colors yet, I'm still using the predefined plcol0 palette
with 16 colors, the documentation did not offer to me a real alternative
(except that it should be possible to change these colors... But how?).
May I ask for a short example how to do this from within Tcl?
