You can set up Cues that appear on the Home page to include an indicator that changes color based on the data values in the Cues.


The indicator appears as a colored bar along the top border of the Cue tile. It provides a visual signal of the status of the Cue's activity, which can indicate favorable or unfavorable conditions to prompt the user to take action.
