#3006 — Coloured points

Can points be coloured? I find linecolor but no
pointcolor.

Maybe these are shown in the example page for the
different line and point types but I have forgotten
how to get that page. How was that?

Extra question: I am asked to use coloured lines,
the colour specified (from a Windows system) as e.g.
Orange:  192, 96, 0 . How does that translate into
gnuplot colour? No doubt rgb <something> but what?

I used the numbers on the colour chart and got the
colours I wanted. Strangely though, the codes are different
from what my coauthor wrote; she uses another, Windows-based,
graphics program. I would have thought that these codes are
common to all graphics programs. Maybe she wrote the wrong
numbers.

I F did and found what I needed, but I am still wondering
whether these codes are universal or specific to different
platforms.

Hm? I'd say that an rgb colour with the same r, g and b value should
be quite universal. Except of course that it will look a bit
different depending on the displays colour profile.

Or which "codes" do you mean?

Dieter,

Posting at least some gnuplot code would probably shorten the response cycle...
What exactly are you plotting, with which color?

Are you (or your colleague) by chance mixing decimal and hexadecimal?
For example #630000 (red-brown) is rgb(99,0,0) (and NOT #990000 which is more red).
If not sure, try using #abcdef as color both at your end and your colleague end, it can't be decimal ;-)

There may be other issues like color profiles, transparency, hard-coded palette and so on.

Kalin.

They're the same.  After all, just about all point symbols are made up 
of lines.
