matplotlib.axes.Axes.locator_params

Axes.locator_params(axis='both', tight=None, **kwargs)

Control behavior of tick locators.

Parameters:
axis : {'both', 'x', 'y'}, optional

The axis on which to operate.

tight : bool or None, optional

Parameter passed to autoscale_view(). Default is None, for no change.

Other Parameters:
**kw :

Remaining keyword arguments are passed to directly to the set_params() method.

Typically one might want to reduce the maximum number
of ticks and use tight bounds when plotting small
subplots, for example::

ax.locator_params(tight=True, nbins=4)

Because the locator is involved in autoscaling,
:meth:`autoscale_view` is called automatically after
the parameters are changed.
This presently works only for the
:class:`~matplotlib.ticker.MaxNLocator` used
by default on linear axes, but it may be generalized.
