This comes from one of our KCS documents which will be published externally within the next 24hrs.
surf(peaks);
xlabel('X Label'); ylabel('Y Label'); zlabel('Z label');
%Call this to rotate the labels
rotate_labels(gca);
%Optional Step. Cause labels to chage as figure is rotated
call_when_rotates = @(~,~,hax)(rotate_labels(hax));
hrot = rotate3d;
set(hrot,'ActionPreCallBack',...
@(hfig,event_data)(set(hfig,'WindowButtonMotionFcn',{call_when_rotates event_data.Axes})));
set(hrot,'ActionPostCallBack',...
@(hfig,~)(set(hfig,'WindowButtonMotionFcn','')));
The rotate_labels function is:
function rotate_labels(hax)
M = view(hax);
R = M(1:3,1:3);
x = R*[1;0;0];
y = R*[0;1;0];
z = R*[0;0;1];
set(get(hax,'XLabel'),'rotation',360/(2*pi)*atan(x(2)/x(1)))
set(get(hax,'YLabel'),'rotation',360/(2*pi)*atan(y(2)/y(1)))

Save the bottom part as rotate_labels.m. Copy the rest into an editor and run it.

it changed my plot inside and the label is still not correct. can you tell me what the problem can be please? thank you so much
subplot(224)
plot3([newxa(end) newxa], [newza(end) newza], [newya(end) newya],'k','LineWidth', 3);
xlabel('Ankle X Trajectory (mm)', 'FontSize',10, 'FontName','NewsGotT', 'fontWeight','bold');
ylabel('Ankle Z Trajectory (mm)', 'FontSize',10, 'FontName','NewsGotT', 'fontWeight','bold');
zlabel('Ankle Y Trajectory (mm)', 'FontSize',10,'FontName','NewsGotT', 'fontWeight','bold');
set(gca,'FontSize',10, 'FontName','NewsGotT');
grid on;
surf(peaks);
xlabel('xlabel'); ylabel('ylabel'); zlabel('zlabel');
%Call this to rotate the labels
rotate_labels(gca);
%Optional Step. Cause labels to chage as figure is rotated
call_when_rotates = @(~,~,hax)(rotate_labels(hax));
hrot = rotate3d;
set(hrot,'ActionPreCallBack',...
@(hfig,event_data)(set(hfig,'WindowButtonMotionFcn',{call_when_rotates event_data.Axes})));
set(hrot,'ActionPostCallBack',...
@(hfig,~)(set(hfig,'WindowButtonMotionFcn','')));
