===========================
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.

    color = 'tab:blue'
    ax2.set_ylabel('sin', color=color)  # we already handled the x-label with ax1

    ax2.tick_params(axis='y', labelcolor=color)

    fig.tight_layout()  # otherwise the right y-label is slightly clipped
    plt.show()
