# Pick text colour based on perceived luminance. In the code below, the value of the figure.figsize parameter in rcParams parameter list is set to (15, 9) to set the figure size global to avoid setting it again and again in different graphs. The drawback is you are creating two different line plots so the connection between the different classes is not shown.
