matplotlib.axes.Axes.set_aspect

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

Set the aspect of the axis scaling, i.e. the ratio of y-unit to x-unit.

Parameters:

aspect : [‘auto’ | ‘equal’] or num

Possible values:

value description
‘auto’ automatic; fill the position rectangle with data
‘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 : None or [‘box’ | ‘datalim’ | ‘box-forced’], optional

If not None, this defines which parameter will be adjusted to meet the required aspect. See set_adjustable for further details.

anchor : None or str or 2-tuple of float, optional

If not None, this defines where the Axes will be drawn if there is extra space due to aspect constraints. The most common way to to specify the anchor are abbreviations of cardinal directions:

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

See set_anchor for further details.
