matplotlib provides rudimentary widgets to build interactive figures. However, those widgets are very rudimentary and do not scale well for anything that needs more than a couple of controllers. A real graphical user interface library is more adapted to creating sophisticated interactions. Fortunately, Python comes with such a library: Tkinter. Tkinter allows you to create some widgets and give them a windows layout. Even better, matplotlib provides a convenient hook to integrate plots to a user interface made with Tkinter. In this recipe, we will be reproducing the previous example, but using Tkinter for the user interface part.
Conveniently, matplotlib provides a special Tkinter widget that we can use to render figures. Updating the figure inside that special widget is done as in the previous recipe. Here are the steps that we need to follow:
We start with the mandatory import directives as follows:
import numpy as np from tkinter...
