<p dir="auto">Hi Nunzio,</p>
<p dir="auto">The issue is that you call <code>ax.set_aspect(‘equal’)</code>, and that changes the axes box. However, <code>ax.get_position</code> returns the <code>frozen</code> position, i.e. the old position. I don’t see a method to return the new position (and I wonder why <code>get_position</code> behaves this way).</p>
<p dir="auto">As a work around, you can get the aspect-ratio changed position as:</p>
<pre style="border:thin solid gray; margin-left:15px; margin-right:15px; max-width:90vw; overflow-x:auto; padding:5px"><code>figW, figH <span style="color: #333333">=</span> fig<span style="color: #333333">.</span>get_size_inches()
fig_aspect <span style="color: #333333">=</span> figH <span style="color: #333333">/</span> figW
newpos <span style="color: #333333">=</span> pp<span style="color: #333333">.</span>shrunk_to_aspect(ax<span style="color: #333333">.</span>get_aspect() <span style="color: #333333">*</span> ax<span style="color: #333333">.</span>get_data_ratio(), pp, fig_aspect)<span style="color: #333333">.</span>anchored(ax<span style="color: #333333">.</span>get_anchor(), pp))
</code></pre>
<p dir="auto">which I appreciate is a bit of a pain….</p>
<p dir="auto">Cheers, Jody</p>

<br>
what I’m trying to do here is having third plot with its base aligned with the others and with reduced height (the final aim is custom positioning a colorbar).<br>
As you can see I’m getting the wrong position. What am I missing?<br>
<br>
Thanks for any help<br>
