Extract coordinate data from plotm figure?

Hello, I made a map from latitude (X), longitude (Y), and elevation (Z) data. Unfortunately, I can't find the original data that I used. However I do have the matlab figure. How can I extract the X, Y, and Z data from the Matlab fig file?

Attached is the matlab fig file I would like to extract the data from.

Something like this:

F = openfig('sample_map.fig');
h = findobj(F,'type','surface');
x=get(h,'xdata');
y=get(h,'ydata');
z=get(h,'zdata');

That's assuming you're after the surface plot data. If there are other objects in the axes which have data you need, you'll have to find them too.

Thanks very much for the response. But I hope to get back the original data I used to generate the plot and not the surface plot data. For example the 'z' variable is filled with all zeros. I hope to get a 'z' variable filled with the attribute data I used originally to generate the plot.

F = openfig('sample_map.fig');
h = findobj(F,'type','surface');
x=get(h,'xdata');
y=get(h,'ydata');
z=get(h,'cdata');
