The configurable comparison legends are available for most types of charts and may be activated directly on a dashboard.
In the Comparison section of the chart settings pane, you can find options for both Significance and Low Base legends.
Three modes for displaying legends are available:
ON: The legend is always visible.
OFF: The legend is always hidden.
AUTO: The legend appears only when there are significance indicators in the chart.
Legends are configured separately for each chart.
Legend settings are retained when cloning and distributing charts.
