[Gnuplot-info] 3D curve with color gradience

[Gavin B. <gav...@ya...>]

Hi, 

This is a good one! Not too sure it can be done. As I
understand it the colors are fairly limited in gnuplot
- and you'd have to draw each section of the curve
separately.

If I was going to do this - using gnuplot (there may
be better packages out there for this problem) - I
would have to mess around with the postscript file.
First of all I would have a limited number of
'segments' for my curve. I would draw each of these in
a different colour (theres only ten colours in ps
term!). Then I would look at the post script file in a
text editor and find the parts with \LT and then a
number. These are the colours and you can play around
with the RGB of them. 

It'd be a pain in the backside if you had to do it
several times though, but as long as you can chop your
curve into a limited number of segmentsit should work.
 I don't know if anyone else can think of a better way
to do it?

Gavin.
