Ok, lets clearify.
Sorry to be some unprecise for what I want to do.
If you are familiar with handle graphics of Matlab, you already know
that using the following command:
h = plot3(x,y,z); // a plot appear.
Let's say you are using x and y to something else later on, and want to
get the dataset used for generation of plot, then you'll can get these by:
X = get(h,'XData'); Y = get(h, 'YData') and Z = get(h, 'ZData')
I want to get these data from gnuplot, is this possible?
Now you are asking yourself, why would you get data from gnuplot, since
you already got them?
Well, for two reasons:
1. There is visualisation application that can change the dataset and
appearance used for visualisation runtime, and some of these might aim
for Octave.
2. Matlab compatibility.
Cheers,
Ole J.
