Re: [ferret_users] use of ppl color for changing line color/thickness

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Stephen,
It's a little different to think about with more colors, but either

set mode linecolors:7
ppl color 7,70,70,70

plot/i=1:100/color=7/thick cos(i/50)

Or

plot/i=1:100/color=14 cos(i/50)

Because there are now 7 distinct colors including the one you defined, the colors, cycle 1, ..., 7 thin; then 8, ...,14 thick; 15, ...,21 very thick.

Hello,

I want to plot data with a thick gray line.  I did:

set mode linecolors:7
ppl color 7,70,70,70

plot/i=1:100/line=7/set cos(i/50)
ppl pen 7 13
ppl plot

I get a thin gray line no matter what I do after /set

According to the color_thickness formula, if I define a new color 7, the color_thickness for a thickness of 3 should be 19, but that doesn't work either.  Eventually, I want to overlay this thick gray line, which I note needs some different syntax.  What am I doing wrong?

Thanks,
Steve
