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.
