Demonstrates one way of embedding Matplotlib figures into a PySimpleGUI window.
|
|
Adapted: From https://gitlab.com/lotspaih/PySimpleGUI/tree/master
|
|
|
|
Basic steps are:
|
|
* Create a Canvas Element
|
|
* Layout form
|
|
* Display form (NON BLOCKING)
|
|
* Draw plots onto convas
|
|
* Display form (BLOCKING)
