So, you want to specify the line color using an exact RGB value? I looked at
doing this once, and I think gnuplot doesn't have this capability. If you
read the man page for gnuplot, it says you can change the default colors by
setting the X resources at startup using a .gnuplot file or command-line
switches with things like this:
gnuplot*line1Color: red
Exactly, I'm really surprised that such a powerful tool as gnuplot does
not allow you to change the color of the plot you make!
The problem is I think it still only recognizes 8 colors. There is a
"palette" line style in 3-D mode, but I don't know if it would help you. For
an example, go into gnuplot and try the command:
splot x*x with line palette
I had a look at this, but it seems only too work with surface, and not
with 3 rows datafiles (i could add one row with my parameter as a third
coordinate)
I'd really like to see the mesh function switch to using this line
style--it's closer to what Matlab does. For a 2-D plot with more control over
line colors, I think you may need to look at some of the alternate graphics
modules that others have proposed.
