How do I rotate the view of a cylinder created using surf plot?

I have created a simple cylinder with radius (r), length (l) and then plotted this to create a surface using the function surf. However, the angle of the plot is such that the cylinder is pointing upwards i.e. z-axis points directly upwards:

I wish to automatically plot the surface but with the orientation change below:

I have attempted to use the view function but can't seem to master this correctly.

Thanks for the help,

Martin

You are using 2 left handed coordinate systems. This is unusual.

Use makehgtform to translate and rotate the object.

[X,Y,Z]=cylinder([0 3],1000);
M=makehgtform('translate',___,'xrotate',___,'yrotate',___,'zrotate',___);
h=surf(X,Y,Z,'Parent',hgtransform('Matrix',M),___);

Also see this answer.

If you're trying to change the orientation of the entire axes, set cameraUpVector or use camup.

ax = gca(); 
ax.CameraUpVector = [0 1 0];

Here is another method, if you want to rotate the surf plot.

figure
[x,y,z] = cylinder(2,20);
obj = surf(x,y,80*z);
xlim([-10 10])
ylim([-10 10])
zlim([0 100])
xlabel('x')
ylabel('y')
zlabel('z')

figure
[x,y,z] = cylinder(2,20);
obj = surf(x,y,80*z);
rotate(obj,[1 0 0],90)
xlim([-10 10])
ylim([-100 100])
zlim([30 50])
xlabel('x')
ylabel('y')
zlabel('z')

figure
[x,y,z] = cylinder(2,20);
obj = surf(x,y,80*z);
rotate(obj,[1 0 0],90)
rotate(obj,[0 0 1],90)
xlabel('x')
ylabel('y')
zlabel('z')
xlim([-50 50])
ylim([-10 10])
zlim([30 50])

Thanks for the reply. The above rotates the surface rather than rotate the viewing orientation, I want the cylinder length to remain along the z-axis.

[Adam Danz]

Perhaps you're looking for view() or camup().

[Kevin Holly]

Did you want something like this?

figure
[x,y,z] = cylinder(2,20);
obj = surf(x,y,80*z);
rotate(obj,[1 0 0],90)
rotate(obj,[0 0 1],90)
xlabel('z')
ylabel('x')
zlabel('y')
xlim([-50 50])
ylim([-10 10])
zlim([30 50])
hold on
quiver3(-50,10,50,100,0,0,'color','k','LineWidth',1)
quiver3(-50,10,50,0,-20,0,'color','k','LineWidth',1)
quiver3(-50,10,50,0,0,-20,'color','k','LineWidth',1)
ylim([-11 12])
xlim([-51 50])
text(40,10,48,'Z')
text(-48,10,32,'Y')
text(-48,-6,48,'X')
axis off

figure
[x,y,z] = cylinder(2,20);
obj = surf(x,y,80*z);
rotate(obj,[1 0 0],90)
rotate(obj,[0 0 1],90)
xlabel('z')
ylabel('x')
zlabel('y')
xlim([0 100])
ylim([0 20])
zlim([0 20])
obj.XData=obj.XData+50;
obj.YData=obj.YData+10;
obj.ZData=obj.ZData-30;

[Martin Doherty]

The orientation looks correct but does this position the cylinder centreline at (0,0,0:80)? It doesn't look like it from the plot above.

[Kevin Holly]

I must have missed your previous comment.

figure
[x,y,z] = cylinder(2,20);
obj = surf(x,y,80*z);
rotate(obj,[1 0 0],90)
rotate(obj,[0 0 1],90)
xlabel('z')
ylabel('x')
zlabel('y')
xlim([0 100])
ylim([-10 10])
zlim([-10 20])
obj.XData=obj.XData+50;
obj.YData=obj.YData;
obj.ZData=obj.ZData-40;
