Good morning, I have a code that, inside a graph follows the movement of the mouse and when you click it saves the x and y coordinates of that point. Later I want to write that x-coordinate in an edit field numeric. The code I have is the following but I have something wrong. I would appreciate if someone could help me.

properties (Access = private)

x

y % Description

end

app.time is the name of the edit field numeric and acc_x the name of the uiAxes

It looks like your callback event "WindowMousePress" may not be triggered. You could add a callback function to your UIAxes as such:

        function UIAxesButtonDown(app, event)
            currentPoint1 = app.UIAxes.CurrentPoint(1,1:3);
            x1 = currentPoint1(1);
            app.tiempo.Value = x1;
        end
