        locators and formatters.  Writing custom locators and
        formatters is rather outside the scope of this example, but
        there are many helpful examples in ``ticker.py``.

        In our case, the Mercator example uses a fixed locator from
        -90 to 90 degrees and a custom formatter class to put convert
        the radians to degrees and put a degree symbol after the
        value::
