difference between axe toolbar in app designer and in standalone application

Hello,

In app designer (R2020b), the default axe toolbar menu is composed of 'export', 'brush','zoomin','zoomout',and 'restoreview' buttons. 'datacursor' is not present but when no button are selected, the datacursor is automatically active and works correctly.

When I export this app as standalone application, only 'export', 'zoomin','zoomout',and 'restoreview' are now available and datacursor function is not active.

Is there a solution to fix this problem?

Thanks for your help.

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!
