[ferret_users] Draw line in x-y-plot

[Arne Biastoch <abiastoch@xxxxxxxxxxxxx>]

Hi Ferreters,

just a quick and (I assume) simple question that struggles me.

Suppose I have a x-y-plot, e.g.

yes? set data levitus_climatology
yes? shade temp[k=1]

How can I draw a single line, e.g. from 10N/110W to 40N/10W?
I tried:

yes? plot/vs/line/over/color=black/nolabel {110W,10N}{10W,40N}
 **ERROR: command syntax: {110W,10N}{10W,40N}
          {110W,10N} before {10W,40N} is illegal

but always get an error.

Thanks,
	Arne
