looping a line plot

[Ricardo Hallak]

Hi Sara,

an animation is make up of several individual figures. First, you have to
build the individual figures with GrADS (say, saving them in .gif or .jpg
formats). Second, the animation should be properly handled with an extra
program, any animation wizard program. You can use some freeware or
shareware program that will animate your sequence of figures and save it in
some animation format supported by Powerpoint (say, .avi).

You can start looking the internet for "gif animation" or something like
that.

Regards,
Ricardo
