st: Beyond grc1leg : common legend from many graphs

[Anupam Tyagi <anuptyagi@yahoo.com>]

I have 4 graphs. Legends in 2 of these graphs have all the information for the
common legend for all 4 graphs. Any one graph does not have all the legend
information for the combined graphs. I want to combine these graphs and use one
legend. How can I do this?

Related: is there a way to save *only* the legend in a graph file?
