Replotting a 2D graph on a 3D surface keeps all 3 axes

Using app designer, I have one UIAxis that allows the user to switch between a 2D line plot and a 3D surface plot. When switching from the 3D plot to the 2D plot the z-axis remains which it is not supposed to. The user should be able to switch between as much as they want.

cla(app.UIAxes);
    if app.DButton.Value == 1                   % 2D check selected
        plot(app.UIAxes,app.xaxis,app.yaxis)    % plot 2 graph
        app.graph = app.UIAxes.Children;
    else                                        % else 3D check selected
        [X,Y] = meshgrid(app.xaxis,app.yaxis);
        [Z] = meshgrid(app.zaxis);
        surf(app.UIAxes,X,Y,Z)                  % 3D surface plot
    end

I'm using cla(app.UIAxes) to reset the axis every time the radiobutton is changed but for some reason the plot is keeping the z-axis even though the code has plot(x,y).

It's supposed to be:

What is actually being plot:

Any help would be appreciated.

cla doesn't reset the view.

Here are some options:

Set the view explicitly: view(app.UIAxes, 2)

Call cla with the reset flag, which will reset the axes to its original state (including getting rid of the labels and other things you've done to configure it): cla(app.UIAxes ,'reset')

Note the presence/absence of the grid in the examples below, surf turns on the grid (if you haven't set it explicitly elsewhere), cla doesn't turn it off, but cla('reset') does.

figure;
surf(peaks);xlabel('x');cla

figure;
surf(peaks);xlabel('x');cla('reset')

figure;
surf(peaks);xlabel('x');cla;view(2)
