Show Legend with Domains

[ftkus]

Hi,

I have a chart split into two domains to show values on different scales (as shown below). I was wondering if there was a way to split the legend to show the relevant items overlayed on top of their respective domain regions, rather than have all items in the same legend?

I occasionally have some charts that use 3-4 domains, so having everything in one legend can get a little crowded and unclear as to what the trend is affiliated with.

I would appreciate any feedback, whether it be a tip on where to look for such a setting, or a recommended alternative approach for resolving this dilemma!

Thanks,
