Python- Bar chart real time

Question

How can I create a bar/column chart in python using animation in real time ? I have made static bar graphs. Currently I have a program that feeds value from a machine to an excel file and my program should read that file in real time and plot a bar graph. I just want to look at patterns. It should update after every 100 points. Thanks in advance !For more clarification I would like to add that it should look like the bar graph in the video provided in the link https://www.pond5.com/stock-footage/58163733/animated-line-bar-charts-business-plan-presentation-showing.html but should not be a image and should update real time data. I am okay if I can do this in Javascript as well. Thanks.

It looks like matplotlib.animation might meet your needs.
