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