Hello Mohamed,

To restrict the zoom option along y-axis, use the "zoom" function. For more information on this function, refer to this documentation: https://www.mathworks.com/help/matlab/ref/matlab.graphics.interaction.internal.zoom.html#mw_93cea585-4eee-4991-b400-aa1250c170d1 .

Here is a simple example showcasing the desired workflow:

• Consider the below plot using "uiaxes" object.

    x = linspace(-pi,pi,50);
    y = 5*sin(x);
    plot(app.UIAxes,x,y);

• Start by disabling the default interactivity options of the plot.

    disableDefaultInteractivity(app.UIAxes);

• Followed by restricting the zoom option to y-axis only.

    zoom(app.UIFigure, 'yon');
