instead of on class.

+    Parameters
+    ----------
+    base : float, default: 10.0
+        The base of the log used, so major ticks are placed at
+        ``base**n``, where ``n`` is an integer.
+    subs : None or {'auto', 'all'} or sequence of float, default: (1.0,)
+        Gives the multiples of integer powers of the base at which
+        to place ticks.  The default of ``(1.0, )`` places ticks only at
+        integer powers of the base.
+        Permitted string values are ``'auto'`` and ``'all'``.
+        Both of these use an algorithm based on the axis view
+        limits to determine whether and how to put ticks between
+        integer powers of the base.  With ``'auto'``, ticks are
+        placed only between integer powers; with ``'all'``, the
+        integer powers are included.  A value of None is
+        equivalent to ``'auto'``.
+    numticks : None or int, default: None
+        The maximum number of ticks to allow on a given axis. The default
+        of ``None`` will try to choose intelligently as long as this
+        Locator has already been assigned to an axis using
+        `~.axis.Axis.get_tick_space`, but otherwise falls back to 9.
