matplotlib slider not working when called from a function

Question

I have the following code, which shows a graph with a slinding bar

    from matplotlib.widgets import Slider
    import matplotlib.pyplot as plt
    from numpy i         


        

Answer 1

Based on this you need to keep the sliders around globally.

Your example would only need to be slightly adjusted:

def myplot(): 
    (... same code as above)
    return szoom

keep_sliders = myplot()
