Problems with Color Bar

[Patrick Reuter]

So easy,

the "set rgb cn r g b" defines the color number cn with a red part r
(0-255), green part g (0-255) and a blue part b (0-255).

so define first your red colors, r.g. 31 to 34

"set rgb 31 255 0 0"
"set rgb 32 200 0 0"
"set rgb 33 100 0 0"
"set rgb 34 50 0 0"

and then your blue colors

"set rgb 35 0 0 255"
"set rgb 36 0 0 200"
"set rgb 37 0 0 100"
"set rgb 38 0 0 50"

and then for example

"set clevs -0.00012 -0.00009 -0.00006 -0.00003 0.00003 0.00006 0.00009
0.00012"
"set ccols 31 32 33 34 35 36 37 38"


Hope that helps

BTW : Do you have some knowledge in interpretating GFS data, for
example ? I would have a question also ...
