Labels don't appear in 3d plot?
显示 更早的评论
I may have posted this question twice, but I didn't see it appear in my profile. Therefore, I'm asking it again.
I applied labels to a 3D plot, but they do not appear. Matlab doesn't show any errors. I've tried removing the position and unit specifications in case it was just offset, but that did not solve it.
clc;clear;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 order you list the assignments and function calls in your code is important.
Try this:
%original figure
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'); hold on
surf(r.*cos(phi),r.*sin(phi),z,'LineStyle','none'); hold off
colorbar;
title('Original Surface Height and Surface with Rotation');
xlabel('Radius');
ylabel('Radius');
zlabel('Height');
The title and axis labels magickally appear!
