This is exactly what I was looking for...thank you!  With this example (and
the docs) I finally understand how the Locator and Formatter classes work.
Now, I just can do this:

        locator = mticker.MultipleLocator(60)
        formatter = mticker.FuncFormatter(lambda x, y: '%02d:%02d' %
divmod(x, 60))

        self.ax.xaxis.set_major_locator(locator)
        self.ax.xaxis.set_major_formatter(formatter)

Thanks again,
