<br class="">
I would like to arrange a number of square subplots (as in subplots with<br class="">
square axes as obtained with `ax.axis('equal')`) in a grid such that the<br class="">
distance between rows and columns is exactly the same.<br class="">
<br class="">
I can use a GridSpec but, as soon as I ask for the axes to be square,<br class="">
the distance between axes changes. Is there a way to enforce the equal<br class="">
distances constrain (namely stretch the padding between the axes and the<br class="">
margin of the figure but do not stretch the padding between axes) or the<br class="">
only solution is to do it manually?<br class="">
<br class="">
Thank you in advance.<br class="">

Best,<br class="">
Dan<br class="">
