[Bug-plotutils] Adding a caption to the output of ‘graph’

[Ludovic Courtès]

Hi,

First of all, thanks for this nice piece of software and for the
pleasant documentation!

One thing I miss from ‘graph’ is the ability to add a caption for the
lines being plotted, particularly in the presence of multiple data sets.

What’s the recommended way to achieve this?  Are there plans to add
command-line options to ‘graph’ to add a caption?

Thanks,
Ludo’.
