Multiple plots in a single chart

It is often useful to contrast data by displaying multiple plots next to each other. This is actually quite easy to when using matplotlib.

To draw multiple subplots on a grid, we can make multiple calls to plt.subplot2grid(), each time passing the size of the grid the subplot is to be located on (shape=(height, width)) and the location on the grid of the upper-left section of the subplot (loc=(row, column)).
