[Rivet] plotting questions

[Hendrik Hoeth]

Hi guys,

Thus spake Andy Buckley (andy.buckley at ed.ac.uk):

yes, I'm on holiday, but I can occasionally access my mail, and since
it's snowing all day today ...

Can you please send me your .dat file? Then I'll have a look at it.

Again, I'd have to have a look at it myself.

As Andy said, you can use any color definition PSTricks supports, which
is anything xcolor supports. So have a look at the xcolor documentation
at
http://www.tex.ac.uk/tex-archive/macros/latex/contrib/xcolor/xcolor.pdf

To use rgb-colors try something like

LineColor={[rgb]{0.8,0,0.7}}

Or you can combine colors in certain ratios:

LineColor=red!50          is a 50% red + 50% white
LineColor=red!30!blue     is a 30% red + 70% blue
LineColor=red!30!blue!65  is a 65% red+blue mixture with red:blue=30:70

In fact there are many more options (hsb, cmyk, wavelengths in nm):

LineColor={[wave]{580}}      is the natrium line, i.e. yellow
LineColor={[cmyk]{1,1,0,0}}  1 cyan, 1 magenta, 0 yellow, 0 black
LineColor={[hsb]{0.5,1,1}}   0.5 hue, 1 saturation, 1 value

Cheers,

    Hendrik
