Plotting of string "category" data: ``plot(['d', 'f', 'a'], [1, 2, 3])`` will
plot three points with x-axis values of 'd', 'f', 'a'.

See :doc:`/gallery/lines_bars_and_markers/categorical_variables` for an
example.

The module uses Matplotlib's `matplotlib.units` mechanism to convert from
strings to integers and provides a tick locator, a tick formatter, and the
`.UnitData` class that creates and stores the string-to-integer mapping.

        Convert strings in *value* to floats using mapping information stored
        in the *unit* object.

        Parameters
        ----------
        value : str or iterable
            Value or list of values to be converted.
        unit : `.UnitData`
            An object mapping strings to integers.
        axis : `~matplotlib.axis.Axis`
            The axis on which the converted value is plotted.

            .. note:: *axis* is unused.

        Returns
        -------
