matplotlib.axes.Axes.set_aspect

Axes.set_aspect(aspect, adjustable=None, anchor=None)

aspect

value	description
‘auto’	automatic; fill position rectangle with data
‘normal’	same as ‘auto’; deprecated
‘equal’	same scaling from data to plot units for x and y
num	a circle will be stretched such that the height is num times the width. aspect=1 is the same as aspect=’equal’.

adjustable

value	description
‘box’	change physical size of axes
‘datalim’	change xlim or ylim
‘box-forced’	same as ‘box’, but axes can be shared

‘box’ does not allow axes sharing, as this can cause unintended side effect. For cases when sharing axes is fine, use ‘box-forced’.

anchor

value	description
‘C’	centered
‘SW’	lower left corner
‘S’	middle of bottom edge
‘SE’	lower right corner
etc.

Deprecated since version 1.2: the option ‘normal’ for aspect is deprecated. Use ‘auto’ instead.
