I do not understand what you want to do. Getting the information on the line objects is straightforward —
I = openfig(websave('X-Ku_intrinsic_parameters_smoothed','https://www.mathworks.com/matlabcentral/answers/uploaded_files/1372719/X-Ku_intrinsic_parameters_smoothed.fig'));
Lines = findobj(I, 'Type','line')
for k = 1:numel(Lines)
DisNm{k,:} = Lines(k).DisplayName; % Get 'DisplayName' Properties Of Each Line
XY{k,:} = [Lines(k).XData; Lines(k).YData]; % Data For Each Line
end
XY
DisNm
Getting the other information from the line objects is similarly striaghtforward, as demonstrated.
