+Demonstrates one way of embedding Matplotlib figures into a PySimpleGUI window.

+Paste your Pyplot code into the section marked below.

+Do all of your plotting as you normally would, but do NOT call plt.show().
+Stop just short of calling plt.show() and let the GUI do the rest.
+
+The remainder of the program will convert your plot and display it in the GUI.
+If you want to change the GUI, make changes to the GUI portion marked below.
