In this article, I denote the way to draw multiple figures in a single file like the image below using matplotlib

Example
- Make sub plot areas using plt.subplots
- Draw each area. In this example, I define and use draw_graph_X functions to draw each figure.
To share a single legend, make a line_list and label_list like this example and set them to fig.legend function.
