Basically, we have a windows-based data collection system, and I would 
like to use octave to visualize data in near real-time as it's being 
collected to verify that I have what I want. So, the plotting is the 
application in this case. The data collection will involve travel to a 
remote site, and it is important to verify while on site that we have 
good data so that the trip doesn't need to be repeated. Then I can do 
all the post-processing I want (on Linux, my preferred platform) when I 
get back to the office.

Doing some data reduction to speed it up is an option, but it's 
frustrating to see Matlab plot something big in a couple of seconds and 
then watch octave and gnuplot spend close to a full minute doing the 
same thing. Supposedly the gnuplot folks are working on this, though.
