Adding "keys" to plots

[gharikum]

Hi,

Well, I've pored over the manual, but have not been able to figure out 
how to add legends to plots. Octave adds line 1, line 2 etc as keys by 
default, and they can be turned off with gset nokey. But how do I add 
some specific lines to the legend?

Thanks.

Hari.
