         Make a plot with log scaling on the *x* axis.

-          semilogx(*args, **kwargs)
-
-        :func:`semilogx` supports all the keyword arguments of

-        Notable keyword arguments:
-
-          *basex*: scalar > 1
-            Base of the *x* logarithm
+        Parameters
+        ----------
+        basex : float, optional
+            Base of the *x* logarithm. The scalar should be larger
+            than 1.
 
-          *subsx*: [ *None* | sequence ]
+        subsx : array_like, optional
             The location of the minor xticks; *None* defaults to
             autosubs, which depend on the number of decades in the
             plot; see :meth:`~matplotlib.axes.Axes.set_xscale` for
             details.
 
-          *nonposx*: [ 'mask' | 'clip' ]
+        nonposx : string, optional, {'mask', 'clip'}
             Non-positive values in *x* can be masked as
-            invalid, or clipped to a very small positive number
+            invalid, or clipped to a very small positive number.
