Dear all,
Is there a way to remove colorbar? axes.cla() clears only the region for map but not the colorbar.

Colorbars are a bit tricky. They are actually a subplot axes separate from your plotting axes. And I don’t think they are very easy to remove. You could do a “cbar.axes.cla()”, but that would still leave the “ticks”, tick labels and the colorbar label.
I am sure that there is a way to get to what you want, but it isn’t immediately obvious. If someone knows how to do it, maybe we should make that into a convenience function? Perhaps cbar.remove()?
Sorry I could not be more help.

Well, I tried with some success the following. Suppose the programme is:
from pylab import *
fig = figure()
ax = fig.add_subplot(111)
data = rand(250, 250)
cax = ax.imshow(data)
cbar = fig.colorbar(cax)
show()
Now, fig has two axes, the main, and the bar. The command
fig.delaxes(fig.axes[1])
gets rid of the bar and the ticks.
Is there anything wrong with that? Of course, I knew that fig.axes[1] was the bar, but finding it in a more complicated case should not be difficult.
All the best.

Thanks Jerzy. It works fine. I may return to this topic for more discussion
later.
