I have spark dataframe df and df1 both with different schemas.

I am building a flutter app for iOS. I have created a file type that my app and another app can share back and forth. I am using the flutter receive_sharing_intent library to achieve this. To test it, I made all the necessary changes to my info.plist file to handle my custom file type, I placed an example file of that file type in the downloads folder of my device (testing on ipad), and I click on it from there to open it up in my app. The OS knows that my app can handle it. So, my app opens, it is receives the path of the shared file, but my app can't open the file. Here is the code in my main.dart that is handling reception of the file:

I try to plot weather radar data to an image and show it using PyQt5. However, everything works fine - but the plots of matplotlib create problems.

When I start the program, it generates 2 empty plot windows and shows them. If I remove the two pl.close() statements, there would be another 2 plot windows (but these 2 with the plot images).

Can you help, why it always opens the plots?

I just want matplotlib to save the plots to a file, to open it later with PyQt. The plots are saved but the the appearing windows are irritating.

When I don't instantiate a PyQt Window, the plot windows appear for a few millisecs and then closes.

I am very new to PyQt and Matplotlib, and I know, the code is not very efficient and beautiful. But I try to build a mockup to learn, how that stuff works. This is my code:
