Add shaded regions to your plot
When plotting time series data in Python, it is also possible to highlight complete regions of your time series plot. In order to add a shaded region between January 1, 1936 and January 1, 1950, you can use the command:
ax.axvspan('1936-01-01', '1950-01-01', color='red' , alpha=0.5)
Here we specified the overall transparency of the region by using the alpha argument (where 0 is completely transparent and 1 is full color).
