I have drawn a 3D plot in app.UIAxes and added x and y axis by xline and y line, but not able to add zaxis line. why I am doing this because in 3D plots, axis is not located at origin. Is there any option like zline?

If all you want is to plot x-y-z axis passing through origin, then you can do the following. (assuming that origin is somewhere inside the plot; otherwise set the xlim, ylim, zlim first).

x=(-2:.1:1);

y = (-1:.1:2);

z = peaks(x, y');

mesh(x,y,z);

hold on

xlabel('x'); ylabel('y'); zlabel('z');

h = gca;

plot3(h.XLim, [0 0], [0 0], 'r')

plot3([0, 0], h.YLim, [0 0], 'r');

plot3([0, 0], [0 0], h.ZLim, 'r');
