Extracting Data from a .fig File

I have this MATLAB figure that I would like to extract the data that made it into a .txt or excel file. It has 7 subplots in it, so i would want the data file to has 8 colums, one for the x values and the corresponding 7 y values. Am I able to do that? And if yes, how?

This should do what you want —

F = openfig(websave('Group10%20heating','https://www.mathworks.com/matlabcentral/answers/uploaded_files/1171588/Group10%20heating.fig'));

Kids = F.Children;
for k = 1:numel(Kids)
    yv(k,:) = Kids(k).Children.YData;
end
xv = Kids(1).Children.XData;

The ‘yv’ array are the YData vectors for each subplot, and the ‘xv’ vector is the common independent variable vector for all of them.
