StandAlone Matlab app don't show the points with the interection with the mouse

I am building an app in matlab app desing that the user needs to interact with the graph with a mouse and in the app designer appears the points like in the figure. But when I create the standAlone app, this interaction with the graph disappears. Does someone know how to solve it?

Are you having your code call datatips() or are you having your code turn on chart interactions https://www.mathworks.com/help/matlab/creating_plots/control-axes-interactions.html

I didn't write a code to access the datatips, always appears to me automatically. But when I compiles the app, this function disappear

[Walter Roberson]

datatips never appear automatically in regular graphs (possibly specialized graphs such as bode plot might enable them.) datatips either have to be turned on with a datatips() call, or chart interactivity has to turn them on, or the user has to click the datatip button in the axes toolbar.

So, How can I call this fuction? beacause in the app designer run test, it work finally, but when I create the .exe, this function dont appear.

[Walter Roberson]

datatips on

[Nélio Dias]

Yes, but where I put this? StartupFn? When the button is pushed?

[Walter Roberson]

When the button is pushed.

[Nélio Dias]

Gives a error message: "Undefined function 'datatips' for input arguments of type 'char'."

This fig reference is the app.UIAxes or the UIFigure?

Enable or Disable Built-In Interactions

To control whether a set of built-in interactions is enabled within a chart, use the disableDefaultInteractivity and enableDefaultInteractivity functions. Sometimes MATLAB® automatically disables the built-in interactions. For example, they might be disabled for charts that have special features, or when you implement certain callbacks such as a WindowScrollWheelFcn.

You can try calling enableDefaultInteractivity after you have plot something on the UIAxes

function plotfunction(app,....)
    % ... code to plot ....%
    enableDefaultInteractivity(app.X); % app.X where X is the name of your UIAxes object
    
    % alternative method to only enable dataTipInteractions.
    app.X.Interactions = [dataTipInteraction]; % app.X where X is the name of your UIAxes object
end
