[Matplotlib-users] Scientific notation digits at left-bottom corner of figure

[Eric Firing]

I'm getting a different result, but on the basic point we now agree: 
the ScalarFormatter is not the right tool for this.  What you need is a 
function that takes a number and returns the kind of string you want.

Examples:

def format_as_int(num):
     return str(int(num))

def format_float_no_sci(num):
     return "%f" % num
