[ncl-talk] Freeze plot in animation?

[Karin Meier-Fleischer]

Hi Sebastian,

you don't need to open a workstation for each plot, because NCL will do 
it automatically,
if you use a Format like "PNG".

Take a look at the NCL animations page 
http://ncl.ucar.edu/Applications/animate.shtml.
The last example is what you are looking for.

Bye,
Karin
