Re: [Matplotlib-users] Save figure without surrounding frame

Not a problem.  Go into your matplotlibrc file and change these lines:

# The figure subplot parameters.  All dimensions are fraction of the
# figure width or height
figure.subplot.left  : 0.001  # the left side of the subplots of the figure
figure.subplot.right : 0.999    # the right side of the subplots of the fig=
ure
figure.subplot.bottom : 0.001   # the bottom of the subplots of the figure
figure.subplot.top : 0.999
figure.subplot.wspace : 0.001   # the amount of width reserved for
blank space between subplots
figure.subplot.hspace : 0.001   # the amount of height reserved for
white space between subplots

They control the white space around the frame where the axes go.  With
the above values, I created the attached plot which I think is close
to what you want.
