1. Where can I find a good tutorial or set of examples for
embeding matplotlib in Tkinter ?
2. Problem: I created a simple test with Tkinter. First I plot my
graph on __init__ (it works ok). Then I want to clear graph and
plot on the same canvas with different parameters. The thing is
that plot shows up only when I resize my window. Any idea what
could I be doing wrong ? I was trying draw method but it doasn't
work...
Here is my code:
