matplotlib.pyplot.axis

matplotlib.pyplot.axis(arg=None, /, *, emit=True, **kwargs)

Convenience method to get or set some axis properties.

Call signatures:

xmin, xmax, ymin, ymax = axis()
xmin, xmax, ymin, ymax = axis([xmin, xmax, ymin, ymax])
xmin, xmax, ymin, ymax = axis(option)
xmin, xmax, ymin, ymax = axis(**kwargs)

Parameters:

xmin, xmax, ymin, ymaxfloat, optional

The axis limits to be set. This can also be achieved using

ax.set(xlim=(xmin, xmax), ylim=(ymin, ymax))

optionbool or str

If a bool, turns axis lines and labels on or off. If a string, possible values are:

Value	Description
'off' or False	Hide all axis decorations, i.e. axis labels, spines, tick marks, tick labels, and grid lines. This is the same as set_axis_off().
'on' or True	Do not hide all axis decorations, i.e. axis labels, spines, tick marks, tick labels, and grid lines. This is the same as set_axis_on().
'equal'	Set equal scaling (i.e., make circles circular) by changing the axis limits. This is the same as ax.set_aspect('equal', adjustable='datalim'). Explicit data limits may not be respected in this case.
'scaled'	Set equal scaling (i.e., make circles circular) by changing dimensions of the plot box. This is the same as ax.set_aspect('equal', adjustable='box', anchor='C'). Additionally, further autoscaling will be disabled.
'tight'	Set limits just large enough to show all data, then disable further autoscaling.
'auto'	Automatic scaling (fill plot box with data).
'image'	'scaled' with axis limits equal to data limits.
'square'	Square plot; similar to 'scaled', but initially forcing xmax-xmin == ymax-ymin.

emitbool, default: True

Whether observers are notified of the axis limit change. This option is passed on to set_xlim and set_ylim.

Returns:

xmin, xmax, ymin, ymaxfloat

The axis limits.

Notes

Note

This is the pyplot wrapper for axes.Axes.axis.

For 3D Axes, this method additionally takes zmin, zmax as parameters and likewise returns them.
