You cannot coerce the xlabel to the top because it's y position is
determined at drawtime to avoid overlapping the tick labels. But you
can place an arbitrary piece of text up there
text(1.0, 1.02, 'testing', horizontalalignment='right',
verticalalignment='bottom', fontsize=14)

position of x label and the y position of y label
Yes, there is...
When calling .set_xlabel(), you can specify the x coordinate of the label
(in units of percentage of the axis width) without naming the y coordinate
(that will be set automatically). You might have to fiddle with the 'ha'
(horizontalalignment) keyword (choices are 'center', 'left', 'right') in
order to align your text relative to the coordinate you choose.
ex:
ax.set_xlabel('Time (s)', x=0.95, ha='right')
You can do the same thing with the 'y' keyword in .set_ylabel(). Instead of
'ha', you use 'va' (verticalalignment) in that case (choices: 'top',
'bottom', 'center', 'baseline').
Maybe we should add an example into the documentation for set_xlabel() and
set_ylabel()? I can see this as a reasonable enough feature for some to
want to seek out.

P.S. - I just noticed that the axis label 'remembers' the keyword properties
that were used in previous calls to set_?label() on that axis. In other
words, if at one point I specify that the ylabel should be at y=0.25 and
then in a subsequent call to set_ylabel(), I don't specify anything at all,
the previous value is used rather than the default.
Don't know if that is a feature or a bug, but this kind of thing would be
more obvious as matplotlib becomes more interactive. At the least, it
probably should be documented in some way.

Sorry, I misread the meaning of and on the top for y axis. As Ben noted, if all you want to do is move the x-alignment, you can pass horizontalalignment to the xlabel command. Just to make it clear for anyone coming across this thread, horizontalalignment alone won't do it. 'ha' only specifies the alignment relative to the text coordinate point, which is 0.5 by default for axis labels. It is by specifying the x (for xlabel) or the y (for ylabel) that will actually move the axis label in any usable fashion.

[Matplotlib-users] Fwd: Bar chart with color map
Hello, I am generating a bar chart following the code in this example: http://matplotlib.sourceforge.net/examples/pylab_examples/barh_demo.html. I am wondering if it is possible to have bar with a colormap (using http://matplotlib.sourceforge.net/examples/pylab_examples/show_colormaps.html). The only piece of code I found close to this is this example: http://matplotlib.sourceforge.net/examples/api/colorbar_only.html.

[Matplotlib-users] colorbar uncentered plots
Hello! see below for sample code.
(1) I find that the second subplot is shifted to the right.
This seems to happen generally with colorbar. How do I fix it?
(2) is there a way to clear/remove selected parts of the figure?
I am using ipython for interactive figure drawing
I find clf() will erase everything, cla() will empty the square plot,
but I can't see how to clear the first subfigure or the colorbar.
This would be useful as any changes to the colorbar create a new one.
(uncomment the second cbar line to see this)
(3) is it possible to modify the orientation of cbar once drawn?
cbar.orientation ='horizontal'
plt.draw()
plt.show()
leaves it unchanged.
Thank you for your help!
Here is my code: ==
#!/usr/bin/env python
import matplotlib.pyplot as plt
import numpy as np
from time import sleep
x = np.arange(0, 10, 0.2)
y = np.sin(x)
fig = plt.figure()
ax1 = fig.add_subplot(211)
cax1 = ax1.plot(x, y)
ax2 = fig.add_subplot(212)
A = np.random.random_integers(0, 10, 100).reshape(10, 10)
cax2 = ax2.imshow(A, interpolation=nearest,vmin=-1,vmax=11 )
cbar = fig.colorbar(cax2)
#cbar = fig.colorbar(cax2, ticks=[0, 5, 10])
plt.savefig('colorbartest.pdf')
