I often "use up" the available mark types -- shape, color, size, etc -- on a number of critical data fields. I then look at the data (usually a map) and use the highlight feature, which is great. However, then I often want to highlight based on a data field (dimension or measure) that I have not used as a mark. Unless I am missing this, it does not seem as if Tableau can do this, at least not easily.
I can use a quick filter, but this has two problems:
1) it is clunky to turn off everything, then turn on one company at a time
2) using a quick filter means that the rest of the data disappears altogether, which means that the context is absent.
Can highlighting capability be extended to new dimensions or measures not used as a Mark?
