MATLAB: Don’t the labels appear in a 3D plot

3d plotsaxis labels

I do not know why my axis labels and title label will not appear in this 3D plot. Matlab doesn't say there's any errors, but the labels just do not exist. I've tried not specifying position(and units), but they still do not appear.
close;
RPM = 25;
R = .05;
h0 = .15;
%define constants and change units
omega = RPM*2*pi/60;                    %[rad/s]
g = 9.807;                              %[m/s^2]
r = linspace(0,R);                      %[m]

phi = linspace(0,2*pi);                 %[rad]
%PLOT
[r,phi] = meshgrid(r,phi);
[X,Y] = meshgrid(linspace(-R,R,2),linspace(-R,R,2));
t = linspace(0,2*pi);
%equation of surface
z = h0 - omega^2/(2*g)*(R^2/2 - r.^2);  %[m]
%h0 (origin) plane
plane = h0*ones(2,2);
plane_1 = h0*ones([1,100]);
%radius at h0
R_h0 = R/sqrt(2);
%original figure
figure('Name','Graphical Display with Original Measurements',...
    'Units','normalized','Position',[.005,.4,.4,.5]);
title('Original Surface Height and Surface with Rotation');
xlabel('Radius');
ylabel('Radius');
zlabel('Height');
surf(X,Y,plane,'FaceAlpha',0.5,'FaceColor',[1,.3,1]); hold on
plot3(R_h0*cos(t),R_h0*sin(t),plane_1,'Color','black'); hold on
surf(r.*cos(phi),r.*sin(phi),z,'LineStyle','none'); hold off
colorbar;

The surf command clears the properties of the axes object, which removes the labels also. So insert them after the hold on:
...
figure('Name','Graphical Display with Original Measurements',...
    'Units','normalized','Position',[.005,.4,.4,.5]);
surf(X,Y,plane,'FaceAlpha',0.5,'FaceColor',[1,.3,1]); hold on
plot3(R_h0*cos(t),R_h0*sin(t),plane_1,'Color','black');
surf(r.*cos(phi),r.*sin(phi),z,'LineStyle','none');
colorbar;
title('Original Surface Height and Surface with Rotation');
xlabel('Radius');
ylabel('Radius');
zlabel('Height');
I prefer to create the axes explicitly:
FigH = figure('Name','Graphical Display with Original Measurements',...
    'Units','normalized','Position',[.005,.4,.4,.5]);
AxesH = axes('Parent', FigH, ...
             'NextPlot', 'add');  % Equivalent to: "hold on"
xlabel('Radius');
ylabel('Radius');
zlabel('Height');
title('Original Surface Height and Surface with Rotation');
surf(AxesH, X,Y,plane,'FaceAlpha',0.5,'FaceColor',[1,.3,1]);
plot3(AxesH, R_h0*cos(t),R_h0*sin(t),plane_1,'Color','black');
surf(AxesH, r.*cos(phi),r.*sin(phi),z,'LineStyle','none');
colorbar(AxesH);
view(AxesH, 3);
Now the Axes Property NextPlot = 'add' enables holding all objects, such that the labels and title are kept also. Specifying the axes' handle is safer than relying on the current object, e.g. if the user click on another axes during the drawing.
