Examples of the shrink kwarg are examples/image_masked.py and 
examples/contour_demo.py.

As an alternative to using the shrink kwarg you can always specify axes 
positions manually.  One example is in examples/multi_image.py. 
Attached is another example modified from image_masked.py.

I have added a bit to the docstring to emphasize the function of the 
shrink kwarg.  This will usually be the easiest manual solution to the 
problem.  I have also thought a bit about adding functionality to the 
axes.draw() method that would allow the colorbar height to track the 
height of the mappable axes object; maybe I will try it later.

The y value of the title instance is in axes coordinates, so 1 is the
top of the axes, and numbers greater than 1 are further above the
top.  So you can do

t.set.y(1.1)

where t is the matplotlib.text.Text instance returned from pylab
'title' or from matplotlib.axes.Axes.set_title (both do the same
thing).

Alternatively, you can set the title instance properties from the axes
instance

ax = fig.add_subplot(111)
ax.title.set_y(1.1)

One of the examples shows how to do this if I recall correctly, but I
don't remember which one.  Eric Firing wrote it so I'm sure he'll be
along shortly to point you to the light.  Eric -- perhaps we should
also add a snippet to the colorbar docstring since this is a common
request.

Petr:  The title command takes 'x' and 'y' keyword arguments that set 
the position of the title in axis coordinates.  For example, try 
'y=1.075' to move the title up a bit.

I usually use the 'shrink' keyword to adjust the colorbar in situations 
like this.  You have to fiddle with it a bit to get the right value.  In 
your case, 'shrink=0.4' ought to do it.

Hello,
i'd like to ask two questions:

1) Is it possible to control amount of space between title and graph?

2) When set_aspect() is used, the size of colorbar does not respect
y-dimension of the graph. (See the attached example.) Is it possible to
set the size of the colorbar directly?

I've seen that it also works with
WxAgg version 2.8.0.1 for python 2.5
I hope this information can be useful
