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

Hi @Deep, Thanks for the code .

I need to Plot XData(1), YData(1)

figure()

plot(XData(1),YData(1));

How to do this?

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 :)
