How to insert scale bar in a map in matplotlib : <p>Any ideas on how can I insert a scale bar in a map in matplotlib that shows the length scale? something like the one I have attached.</p>

<p>Or maybe any ideas on measuring and showing distances automatically (not drawing an arrow and writing the distance manually!)?</p>

<p>Thanks :)<a href="https://i.stack.imgur.com/tODjr.png"><img src="https://i.stack.imgur.com/tODjr.png" alt="enter image description here"></a></p>
