plotting legend labels for each curve

[David DS Barnes]

Hi,

I wondered if anybody could help me here;

I can plot a key from octave,
but have had no luck actually labeling each curve in the key

eg, if I had a sin and a cos curve
how can I put one as "sin" and one as "cos" in the key?

Thanks in advance,

David
