Summary Graphs

I've got a summary graph that compiles multiple graphs together. I'm
getting the following output:

Is there a way to rename the captions in the graphs? Right now, it
appears to be combining the Legend and the DS Name. I'd rather it
include each target's display-name, as that's something more
meaningful.

Thoughts?

Thanks,

Norman Elton
