 Bar demo with units
 ===================
 
-A plot using a variety of centimetre vs inches 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).
