Hi Folks,
I recall from time to time comments about the non-beauty of gnuplot plots, but
in my opinion comparing them against other plotting software in common use on
Windows machines I find them clean and simple. The colored backgrounds of
other plotting programs get kind of old after a while. Also, gnuplot X11 makes
good use of a window by keep margins thin by default. Some other programs
leave all kinds of space in the margins. In any case, Octave graphics is
pretty nice right now.
The one area where Octave seems a bit limiting is working with large data.
Octave seems to require so much memory in order to load memory. (Well, should
assume it's Octave, could be Linux that has memory issues.) From my rough
guess, Octave requires free space of about 6-9 times the size of the file being
loaded, at least for ASCII files. For example, using 'load' on a 100 MB file
will push Linux to the edge of 1 GB memory and the system will slow to a crawl.
What seems to happen is that a lot of memory is used to load data, then after
the data is loaded the memory will drop down to something that reflects what
one might guess. John, what are your feelings on memory usage by Octave?
Could it be more efficient? Is Linux not as efficient as it could be?
Dan
