Hi Philippe,
I understand that you are unable to get the "datacursor" function in the standalone application.
To fix this issue, you can create custom datatips for your plot. Here is an example how you can do so:
methods (Access = private)
function output_txt = myUpdateFcn(app,info)
% Get the datatip position
y = info.Position(2);
x = info.Position(1);
% Create the datatip text
output_txt = {sprintf('X: %.3f', x), sprintf('Y: %.3f', y)};
end
end
% Callbacks that handle component events
methods (Access = private)
% Code that executes after component creation
function startupFcn(app)
x = [0 1 2 3 4 5 6 7 8 9];
y = [0 1 2 3 4 5 6 7 8 9];
plot(app.UIAxes, x, y);
dcm = datacursormode(app.UIFigure);
dcm.Enable = 'on';
dcm.DisplayStyle = 'datatip';
dcm.UpdateFcn = @(src, event)myUpdateFcn(app, event);
end
end
- In the “startup” function, a line plot is generated using random data. Then the “datacursormode” object (“dcm”) is enabled and set to display datatips. The “UpdateFcn” property is set to the “myUpdateFcn” function, which will be called when the datatip is updated.
- Inside “myUpdateFcn”,the x and y coordinates are extracted from the “info.Position”property. The datatiptext is created using “sprint”to format the x and y coordinates with three decimal places.
For more information about “datacursormode”, you can refer to the following documentation link:
I hope this helps!
