Set value of a view filter

I’m looking for a way to set a value of a view filter…so i want to set the value under filter rules.
I have been looking at the forum but searching for the word filter gives a lot of hits on lists.

I want to set the value and then export the view as an image. This way i can visualize the planning. When the planning changes i can rerun the script.

How can i get to these values
