[Matplotlib-users] absolute positioning of a subplot in a Figure

[TP <par...@fr...>]

Hi everybody,

Below you will find a small script that plots the graph of a simple function. 
This code is aimed to be embedded in a GUI application.
I set the subplot dimension with the b.set_position([]) command. The floats 
that are given to set_position() are percents relative to the Figure 
dimensions:

[ left corner x, left corner y, width, height ]

So, here I have put [0.1, 0.1, 0.8, 0.8 ] to have a small space between the 
subplot and the Figure border.
But when I resize the figure with the mouse, the space between the subplot and 
the Figure border is growing or decreasing, due to the relative definition of 
the dimensions.
I would like to be able to define subplot size and position in an absolute 
way. For example, I would like to have a space between the left border of the 
figure and the left border of the subplot being constant equal to 10px.

Is this possible?

Thanks a lot

Julien
