Jupyter: How To Update Plot On Button Click (ipywidgets)

I am using Jupyter and trying to make my plots interactive. So I have a plot. I have a ipywidgets button. On button click I need to update plot, like interact do with sliders. But

Solution 1:

As workaround we can repaint the whole plot to Output widget and then display it without flickering.

%matplotlib inline

from matplotlib.pyplot import *

button = ipywidgets.Button(description="Button")
out = ipywidgets.Output()

def on_button_clicked(b):
    with out:
        clear_output(True)
        plot([1,2],[2,1])
        show()

button.on_click(on_button_clicked)

display(button)

with out:
    plot([1,2],[1,2])
    show()

out
