Visualize CSV data in QT based GUI

[Trayach]

Hello!
I'm trying to visualize data from CSV files in QT-based GUI.

I have a CSV file and GUI. I would like to know how to link those two and plot the data in my GUI.
I've tried to manage the necessary code to find the file's location and plot but couldn't visualize the data.

Issue - I couldn't able to link my GUI with the CSV file, which ends up visualizing nothing.

Would anyone please let me know how to achieve this?
Thank you!
