Displaying an animation / "movie"

[Jeff Miller]

Robert,
Thanks for the reply. I don't really need to create a separate movie
file to replay later, I just need to be able to visualize the series
of images once... Is there a way to view images sequentially in the
same window?

I suppose I could use the approach you described to automatically save
the images to files, create a movie file, replay it, and then delete
all the files. That just seems more complicated than what I'm trying
to do. But if it's the only way...

I noticed that Gnuplot 4.1 (developmental) supports images (I only
have 4.0). That might work, but it's a gamble.
