I just started to use matplotlib for a small project involving graph generation. I'd like you to help me to solve a simple problem: I assign to axes values that range from 0 to 100 bilion. The library approximate the values to fit correctly the layout, an it places the exponent that should be used to retrieve the right value on top of the axes. I need to change this behaviour, and I'd like matplotlib to show the full exponent (1000 instead of x1e3 for example).

How can I do that?
