""" =========================== Plots with different scales =========================== Two plots on the same Axes with different left and right scales. The trick is to use *two different Axes* that share the same *x* axis. You can use separate `matplotlib.ticker` formatters and locators as desired since the two Axes are independent. Such Axes are generated by calling the `.Axes.twinx` method. Likewise, `.Axes.twiny` is available to generate Axes that share a *y* axis but have different top and bottom scales.
