@alxnddr@Ovilia any chance we can get this PR merged soon?

I think lines should also be gray when out of range. This PR only makes item gray. @alxnddr Please update the implement to make sure the lines are also working as expected.

I have a branch open with these changes and I've added a test -- if you can point me in the right direction of where to set the line color (I have a hunch I need to use a rectangular selection in the brushSelector) I can finish this pr. cc @Ovilia

Hi @iago-f-s-e, since it looks like the PR is no longer up to date, I wanted to ask if you have found a workaround to get the selected data. Thanks for the help
