How to update the Tkinter graph?

In Excel, How can I make the graph change by adding or taking away data? When I do, it doesn't update graph?

• I added future weeks into my data. However, my boss doesn't want it that way...he says it looks like we are low in production. So, each week I have to do a WHOLE NEW graph for the new week. Isn't there an easier way? Because when I subtract the weeks I don't want from the data, it doesn't update the graphs, and on the graphs, it won't allow me to just delete the weeks. I use both kind of graphs with one data....I use a line graph and I also use a bar graph. Thanks
