looping a line plot

[Rauscher Sara A]

Hi Matt,

Thanks, but that's not what I meant, I wasn't clear enough. I can plot a
times series just fine - using 'define' plus 'set t 1 12' will give the
same results as tloop. What I want to do is to create an animation,
where the first frame of the animation would show the value for January,
for example, and then with each frame a new month would be included in
the curve, so that the annual cycle is animated (or is drawn gradually),
it doesn't appear all at once.

For example - see the movie at
http://www.gfdl.noaa.gov/research/climate/highlights/images/ani/SahelPR_ANN5yr_CM2Q_h1_A1B_6fps_720x480.mpg
I would like to create something like the line plot on the right-hand
side (the blue line plot that is drawn gradually).
