Hi, I'm using the app designer and i want to select some points from a plot.
in the UIAxesButtonDown function I'm using this notation to "capture" the mouse position:
C = get (app.UIAxes,'CurrentPoint');
app.UITable.Data = C(1,1:2);
the problem is that I don't know how to store the X and Y values of the point I just clicked, because if I click again on the plot it will overwrite the previous point.
Thanks

Hello,
It would be the best if you put data tips on the points you want to select then you can get them with these lines
dataTips = findall(fig, 'type', 'datatip'); % where the fig is your figure handle
pointCoords = cell2mat([get(dataTips, 'X'), get(dataTips, 'Y'), get(dataTips, 'Z')]);
