Is there a way to prevent the legends from overlapping?
Behind "mem_start" and "mem_end" you can see the second legend in light gray.
My preferred solution is an "intelligent" way. I mean a solution where I don't need to specify the location explicitly. This chart has two legends. The next might have five .... I love it if it works on its own.
