[ferret_users] Edit plot's labels

[Paulo Henrique <paulohsm@xxxxxxxxx>]

Hi Ferret Users,

I'm not experienced with PPL commands and syntax, and I don't know how to modify some default issues on my plots. 

I'm using the command

plot vlm1, vlm2, vlm3, vlm4, vlm5, vlm6, vobs

and I get these labels in my plot, listed by "ppl list labels" command:

The variables are defined with the command "let/title=..." where the default label text must be the variable title - but it don't happens.

I would like to modify these default labels text  (specifically "LAB 5" to "LAB 11") and eventually remove someone (maybe "LAB 4"). 

I think it's not difficult, but I tried some commands and got no results. So, how can I do this?

Thanks in advanced.
