I have a problem with slice filtering in graphical views,

I’m having problems with resolution because the content in the line chart is too much.

In short, how do I filter the lines that are connected to the key 'in the graphical view?

ANY(Filter[SERİ NO]) = [Seri No]

unfortunately did not happen this way

Little bit difficult to understand your goal, but how about…
IN([Seri No],Filter[SERİ NO])

Unfortunately, this did not happen,
As with the “col series” card, the “col series (line)” graphs should change the values on the y-axis according to the content filtered, but unfortunately not changed

I think the system doesn’t work well in the col series (line) card because the value of the content that I didn’t select remains on the y-axis.
