How to add a single legent with multiple subplots with out overlapping on plots?

2 views (last 30 days)
Hello All,
I am trying to add a add a common legend for all my subplots in a graph. But I dont have extra space for the legend to add on the plots. They are overlapping on one another. I need something like in the image. Can some one please hlp me with it. My code is as follows:
Thanks in advance.

Thank you for the reply. But is it possible to have it completely outside of the plots, not in between.

Hi!
I am having a similar issue, only that I wnat my Legend below the tiles.
Unfortunately it covers a part of the xlabel. Hast anyone an Idea on how to fix this?

I noticed it was missing.
I have no idea how it got deleted, and just assumed you deleted it. Rena Berman might have some insight into that.
