opto | Python interface to Optotune focus-tunable lenses

Hy, I hope you are all doing well. I am building a Eye chart software in python tkinter which consists of Opto Charts. In Opto Charts all alphabet comes directly below each other. But when I try to add labels in tkinter, it forms V shape as with each row font size is decreasing. I want to occupy the label all the available space.

I managed to do that using mainFrame.rowconfigure(0, weight=1) but it only makes the label to full width not the text inside it. I have attached a screenshot for how it looks. In the screenshot you can see the labels are set to full length of screen but text is in V shape as font size is decreasing from top to bottom. Is there a way to anchor the text to full width also. In others words each alphabet should come directly below the above one.

I hope I was clear, If you need to know anything else let me know.

Note: This is a question relating to mouse EEG data plotting.

I made a plot showing the averaged trial signals for filtered EEG electrode channels. While plotting this I saw a few signals that I want to exclude from my plot, but I don't have a way to tell what channels were plotted. Is there a way to add something that would allow me to click on or hover over one of the plotted lines/channels and have my jupyter notebook tell me what channel I clicked/am hovering over?

This is the plot I am hoping to make clickable:

Here is the code I used to make the plots if that's helpful:

I can add multiple partialview dynamically into my page like this
