Since the ability to modify the highlight action in this manner is not yet built into the Tableau Desktop product I would suggest some of the following options:
1. Suggest the ability to format or control the highlight action filter in a different ways to the Tableau Community Ideas Forum: Ideas
2. As a workaround, you could try to use a filter action instead of the highlight action. To filer down to the specified points as desired. This would give a similar affect as to them fading to 0% opacity on the sheet. (though the sheet might reformt depending on how much data is filtered etc..)
Hope this helps!
Thank you Patrick for the response. I have multiple charts in detail section so action filter is not the good choice because the charts are reformatting and it looks ugly.
I have a summary chart at the top and in the bottom I have detail charts arranged like a 6x6 matrix. When I apply a action filter, after filtering some charts wont show and rest of the charts reformatted and occupying entire bottom space and coming in different sizes. That's why I suggested for highlight option.
