10.1.1. The render backend does not work

Usually, the render backend from matplotlib should open an interactive window. If this is not the case, there is some error with the installation. As a quick fix you can avoid the interactive window, by using the plt.savefig to store the graph on your filesystem. If you want to draw a new graph, you need to remove the old graph from your memory. Usually, this is done automatically, by closing the interactive window. Call plt.close to to this task manually.
