Thread Subject: Exporting data from .fig to matlab

Hi there:
i have a figure .fig, from which i lost the data and i want to export the data into matlab, without needing to copy point by point. I tried from properties, Xdata and Ydata, but for that i would have to copy point by point (and there are a loooot of them).
Can someone help me? I believe there is an easier way....

Tanks in advance!

It is not clear to me why you think you would have to copy point by
point?

alllines = findobj('Type',line');
nlines = length(alllines);
thepoints = cell(nlines,2);
for K = 1:nlines
  thepoints{K,1} = get(alllines(K),'XData');
  thepoints{K,2} = get(alllines(K),'YData');
end


What happens after this depends on the structure of your plot and
how much of that structure you want to preserve.

This code depends upon your plot being composed of lines, not surfaces
or patches or contours... you didn't say.

If you can be satisfied with approximate reproduction of
the data, you can try the program 'convert' you can
download it from the file exchange it may help
