Hello
Dear experts,
I have a .fig scatter plot (actual data vs. predicted data), and I need to extract the data points. is the .fig file able to show the X and Y values?
Regards,

openfig('YourFigFile.fig')
hSc=findobj(gcf,'Type','scatter');
.X|Y|ZData properties are available from the scatter object handle thus obtained.

Thanks for your reply, however, it does not show the X and Y datapoints. This command only shows the "properties" that is already available on the property inspector window.

Well, you have to retrieve them from the scatter object...I don't know what you mean by "show"...the command line echos the actual values if the arrays are of minimal size but you wouldn't want a 10,000 element vector scrolling across the command screen if that were the size of the figure.
X=hSc.XData;
etc., etc., ... Figured that would be obvious at that point.
