Hello,
I have some stupid questions about how to use colorbar.
1) I would like to be able to put the colorbar where I went: top, bottom,
left, right. For what I see I can do only a vertical left and horizontal
bottom ones (with a simple use of the function).
I know that it's possible to do a colorbar only but it's difficult to place
them a little bit automatically and that bring my second question.
2) I would like that the colorbar with exactly the same size than the image I
plot with pcolor. It's working when I'm not using the aspect='equal' in the
subplot but not with this option. Naturally I want to not change the aspect
of my image and so it's a big problem for me. The only solution I found is to
manipulate the colorbar with the shrink valu but it's a little bit painfull
especially the value change for each pcolor image (they doesn't have always
the same size).
3) I would like to give a label to the colorbar (ie if the colorbar is at the
bottom a label under the colorbar etc). To tell people what means the colors
but I didn't find anyway to do it. xlabel work for the pcolor object (as
expected) and there are no colorbar.xlabel function.
Thank you for any help.
N.
ps: i join a simple script to show my problem
#!/usr/bin/env python
import pylab
import numpy
a = numpy.arange(100).reshape((10,10))
fig1 = pylab.figure()
ax = fig1.add_subplot(141)
im = ax.pcolor(a)
fig1.colorbar(im,orientation='horizontal')
pylab.xlabel('label')
ax = fig1.add_subplot(142)
im = ax.pcolor(a)
fig1.colorbar(im,orientation='vertical')
pylab.xlabel('label')
ax = fig1.add_subplot(143,aspect='equal')
im = ax.pcolor(a)
fig1.colorbar(im,orientation='vertical')
pylab.xlabel('label')
ax = fig1.add_subplot(144,aspect='equal')
im = ax.pcolor(a)
fig1.colorbar(im,orientation='horizontal')
pylab.xlabel('label')
pylab.show()
