===================
Bar demo with units
===================
A plot using a variety of centimetre and inch conversions. This example shows
how default unit introspection works (ax1), how various keywords can be used to
set the x and y units to override the defaults (ax2, ax3, ax4) and how one can
set the xlimits using scalars (ax3, current units assumed) or units
(conversions applied to get the numbers to current units).
