[Feature Request] Line Chart: Split by Group

[ajdapretnar]

Implement 'Group by' option as found in Distributions. This allows the user to view line chart per each, say, class value individually on the same plot.
Very handy! 👌

How would you distinguish between groups? Different colors already represent different variables.

Perhaps allow splitting by group only when showing a single line, so the colors can be used to represent groups?

I agree, this doesn't work with plots containing multiple variables. Probably the only solution is to limit this option to a single variable.
