Method _set_axes_scale

lib/matplotlib/axis.py:802–831

Set this Axis' scale. Parameters ---------- value : str or `.ScaleBase` The axis scale type to apply. Valid string values are the names of scale classes ("linear", "log", "function",...). These may be the names of any of the :re

(self, value, **kwargs)

        Set this Axis' scale.

        Parameters
        ----------
        value : str or `.ScaleBase`
            The axis scale type to apply.  Valid string values are the names of scale
            classes ("linear", "log", "function",...).  These may be the names of any
            of the :ref:`built-in scales<builtin_scales>` or of any custom scales
            registered using `matplotlib.scale.register_scale`.

        **kwargs
            If *value* is a string, keywords are passed to the instantiation method of
            the respective class.
