Hi, this will extract the data of the 4 lines from the .fig file and store them in XData and YData. The code should be self explanatory.
open('untitled.fig');
% Get the current figure and its children
f = gcf;
axes = f.Children;
% Initialize XData and YData as cell arrays
XData = {};
YData = {};
% Loop through the axes
for a = 1:length(axes)
ax = axes(a);
% Loop through the axes children
for i = 1:length(ax.Children)
% Check if the current child is a line object
if isa(ax.Children(i), 'matlab.graphics.chart.primitive.Line')
XData{end+1} = ax.Children(i).XData;
YData{end+1} = ax.Children(i).YData;
end
end
end
close(gcf);
disp(YData(1)); % Display the current values for the 1st line

You'll need to convert the cell to an ordinary array.
x = cell2mat(XData(1));
y = cell2mat(YData(1));
plot(x, y);
If the answer helps, please approve it :)
