Hi! I am trying to incorporate a function or button in a GUI via GUIDE, so as to show me the tilte of each plotted line in a plot.
Namely, I am plotting various spectra (i.e. x,y data) and I would like to click on each line and get the title of the spectrum (see attached a picture)!
Could anyone provide me with a hint on how to do this?
Thank you in advance!

You can define a ButtonDownFcn for the lines:
LineH(1) = plot(1:10, rand(1, 10), 'r', 'DisplayName', 'Line 1');
LineH(2) = plot(1:10, rand(1, 10), 'b', 'DisplayName', 'Line 2');
TitleH = text(0.01, 0.01, '', 'Units', 'normalized', ...
'VerticalAlignment', 'top');
LineH.ButtonDownFcn = {@showTitle, LineH, TitleH}; % [EDITED] Typo: "," -> "="
function showTitle(aLineH, EventData, LineH, TitleH)
TitleH.String = aLineH.DisplayName;
LineH.LineWidth = 0.5;
aLineH.LineWidth = 1.5;
uistack(aLineH, 'top');
end
