Hi,

I am a bit confused about the demo script at the Gnuplot site,

<http://gnuplot.sourceforge.net/demo/animate2.1.gnu>.

It seems that the variables defined immediately before the splot command
do not have any function. Consequently, the script along with the
world.dat file does not create an animated GIF but only a static (but
nice, however ;-)) globe.

The commands shown on the web page should work, although as you point
out they call a separate file "gnuplot.rot". I will manually edit
the page so that it shows the auxilliary file as well.

The downloadable script is auto-generated by a tool that unfortunately
does not know about animation, and in this case gets it wrong.
The same tool also fails in the case of multiplot demos.
I suppose I could patch it up by hand, or more likely just delete
the downloadable script from the on-line pages for which it doesn't work.

All of these demos are distributed with gnuplot, so you should already
have a local copy to play with. The motivations for the on-line versions
are
- to show people what they would get if they did install gnuplot
- as useful reference points for on-line discussions, as in
"Are you trying to make a plot like the one at URL <...>?


I could not find any hints about sequence
plots in GP 4.2 and can only guess that it works in the same way as I
already used it in Gnuplot 3.7 (repeatedly re-reading a separate file
that contains the plot command) for on-screen "movies".

Yes, the separate file is a loop that increments view angles and then
replots. But the output goes into an animated gif file, not onto the
screen.
