For each .fig file:
F = openfig(filename);
Lines = findobj(F, 'Type','Line');
Then, for each element of the ‘Lines’ array:
for k = 1:numel(Lines)
x{k} = Lines(k).XData;
y{k} = Lines(k).YData;
end
It obviously depends on what information are in the .fig file, however this is the usual method for recovering the data vectors or matrices from them.
You will need to do this for each .fig file, so you will need to keep the ‘x’ and ‘y’ cell arrays separate. One way is to use an outer loop to loop through the .fig files:
for k1 = 1:NumberOfFigFiles
F = openfig(filename(k1));
Lines = findobj(F, 'Type','Line');
for k2 = 1:numel(Lines)
x{k1,k2} = Lines(k2).XData;
y{k1,k2} = Lines(k2).YData;
end
end
You can then do whatever analyses or plots you want with the ‘x’ and ‘y’ cell arrays.

To read them and then plot them together:
FigFile{1} = '103_RU.fig';
FigFile{2} = '118_RU.fig';
for k1 = 1:numel(FigFile)
F = openfig(FigFile{k1});
Lines = findobj(F, 'Type','Line');
for k2 = 1:numel(Lines)
x{k1,k2} = Lines(k2).XData;
y{k1,k2} = Lines(k2).YData;
end
end
figure
for k1 = 1:size(x,1)
for k2 = 1:numel(x,2)
plot(x{k1,k2}, y{k1,k2})
hold on
end
end
hold off
