You will probably want to add axes explicitly (not with subplot), e.g.

fig.add_axes([.1,.1,.71,.8])

specifies the coordinates of one corner and the width and height (in  
proportions of the figure size). When doing this explicitly, you will  
probably need to do some extra adjustments to fit the axis labels and  
so forth.
