⇨

Output Stack: StyleExpr

Set the palette to use for the results of an expression. This operator is allows for scoping a palette to a particular group by instead of to all lines that share the same axis. A common use-case is to have multiple stacked group by expressions using different palettes. For example, suppose I want to create a graph showing overall request per second hitting my services with successful requests shown in shades of green and errors in shades of red. This can make it easy to visually see if a change is due to an increase in errors:

Or a spike in successful requests:
