Multiple units (How to display multiple units in one graph?)

How to display multiple units in one graph?


Left and right y axis can have different units

I have one graph and 3 metrics (A/B/C).
how can i assign different units?

You can’t. That might work in the legend but how would you show that on a graph? There are only two y-axes in a line graph (and the x axis is for time).

Maybe something like a scatterplot would help if you want to show 3 dimensions:

How can I use a third unit in the legend? I have three queries. The third unit in legend would be ok.
