<p><em>y</em> coords are in data units and <em>x</em> coords are in axes (relative
0-1) units.</p>
<p>Draw a horizontal span (rectangle) from <em>ymin</em> to <em>ymax</em>.
With the default values of <em>xmin</em> = 0 and <em>xmax</em> = 1, this
always spans the xrange, regardless of the xlim settings, even
if you change them, eg. with the <tt class="xref py py-meth docutils literal"><span class="pre">set_xlim()</span></tt> command.
That is, the horizontal extent is in axes coords: 0=left,
0.5=middle, 1.0=right but the <em>y</em> location is in data
coordinates.</p>
