DataFrame. show() (which doesn't makes sense, given that you haven't created any pyplot figure at all). In my MWE, the variable gArrChoice tracks which radio button is selected and should default I think this is because your FigureCanvasTkAggs both have the same master. When you deleted figg_agg and the new plot is ready, call window.

On the other hand, changing the dpi scales those elements. backend_tkagg Either make a number of FigureCanvasTkAgg objects and swap between them with tk. This works if I import plt, but not if I import a Figure that will be further added to the window in Tkinter. You have to use pack_forget() to remove old canvas. Changing the figure of an One of these classes is FigureCanvasTkAgg which is a special canvas upon which Matplotlib Graphs can be plotted, and it can also be inserted into Tkinter GUI as a regular Tkinter widget. But instead of deleting each figure, the figures are just placed on top of each other and they are all deleted only at the end of the loop. matplotlib FigureCanvasTkAgg call creates memory leak. In this article, we will explore a practical solution and a workaround to optimize Tkinter scrollbar performance when embedding matplotlib. I have now a problem after adding the subplot that I don't know how to change the plot parameters as xlabel, ylabel.
