What is the unit of height variable in "barh" of matplotlib?
<p>In the definition of the function barh of matplotlib:</p>

<p><code>matplotlib.pyplot.barh(bottom, width, height=0.8, left=None, hold=None, **kwargs)</code></p>

<p>The default "height" is 0.8, but when I draw some figures with different Figure's height for example (30, 40,..) and dpi=100. I see the Bar's height is changed. It's not fixed. So I wonder what is the unit of the height in barh and how to make it fixed (not depend on figure's height).</p>
