Easier way to turn on and off active dataset indicator (red frame) in Legend via:

Version: 2018

Type: Features

Category: Graphing

Subcategory: Text Labels & Legends

Jira: ORG-16143

The red frame around plot part of legend is the activate dataset indicator. Analysis, etc. tools always work on active dataset by default. So it's useful to see it sometimes.

The control to turn it on or off is hidden on Legends/Titles tab of Plot Details dialog in the past and hard to find.
