[matplotlib-devel] Bar plot forget units information

"""=0A=
plot using a variety of cm vs inches conversions.  The example shows=0A=
how default unit instrospection works (ax1), how various keywords can=0A=
be used to set the x and y units to override the defaults (ax2, ax3,=0A=
ax4) and how one can set the xlimits using scalars (ax3, current units=0A=
assumed) or units (conversions applied to get the numbers to current=0A=
