Hi,
I'm trying to make a few matplotlib scripts work on a box without any
X. However, I would like to change it as little as possible and
therefore don't want to get rid of the pylab interface.
I almost got it to work already by just using the "dummy GUI", i.e. i
use
import matplotlib as m
m.use('Template')
import pylab as p
This works fine except for one little detail.
I've always had the problem that there doesn't seem to be a(n easy) way
to set the limits of a colour bar. However, as I need the colour scheme
to be constant across the different plots, I have always used the trick
of first plotting a 1x2 grid with the minimum and the maximum value and
then overwriting that with the actual plot. That way the colour bar
uses these values as it's extrema while these extrema are not
necessarily visible anywhere.
The problem I have now is that the overwriting doesn't work any more
with the trick of using the empty template for the GUI. Instead of
covering the existing pixels, they now show up in the bottom left
corner of my actual plot. If I remove that first plot, I lose my
constant colour bar but if I keep it, I have bogus pixels in my plot.
Any hints how to solve this dilemma?
Cheers,
Christian
