how to filter multiple lines in Graph

[Agrint]

hey  experts,
I have a graph with multiple lines that set as measures and date as dimension,
the graph looks like this:

 now I want to be able for an instance to filter just the "high" measure. perhaps it should be done with a filter pane but because its a measure it showing me all the "high" option (1,2,3 etc...) instead of just being able to press high.

please, some help on this one pretty lost here.
