I am not sure if you are trying to move objects from one axes to another or
merely reposition an existing axes to make room for a new one.
Both are possible, but the latter is easy. Each axes has [left, bottom,
width, height] rectangle in (0,1) figure coordinates that you can adjust at
any time. See for example the subplots_adjust tool on the navigation
toolbar next to the save icon
http://matplotlib.sourceforge.net/api/axes_api.html#matplotlib.axes.Axes.set_position
If you are working with subplots, also see the change_geometry method
http://matplotlib.sourceforge.net/api/axes_api.html#matplotlib.axes.SubplotBase.change_geometry
colorbars are a little tricky, because there you are needing to reposition
*two* axes, one for the image, and one for the colorbar itself. You can do
this manually, but you probably want to look at JJ's gridspec and axes_grid
tools for laying out groups of axes:
