Re: Controlling colour coding in image plots

[David L Lorenz <lorenz@usgs.gov>]

Kim,
  It's been a while since I've worked on motif graphics, but look in the
documentation for motif. It should contain a reference to .sgraphrc, which
is a X-resources file that sets up the color (and other) choices for motif.
Hopefully there is enough information to help you set up one that you like.

MessageHi Kim,

I don't know the answer to 1) but suspect that you can't. The answer to 2)
is rather simple: use the the zlim argument in image() to keep the
intervall
of values covered in the image constant throughout your plots. That will
also keep the color assignment constant.

Subject: Controlling colour coding in image plots


I am using image() for coloured plots. I have two questions:

1) How do I specify colours other than by changing them in the graphics
device (e.g. motif)
2) How can I control the colour coding, so that when using different
datasets I always maintain the same colour for the same interval?
