How can a show the correct view of graphical objects??

I am trying to make an animation, and I noticed that the camera DOES NOT show what it should show. How can I fix this?

I make a unit circle, and place the camera directly above the central point and set the camera target to a far away location outside the circle with a narrow field of view. Obviously, from this view I should not see the entire circle, but I do.

PLEASE ANY ADVICE!?

t = linspace(0,pi,100);

x = cos(t);

y = sin(t);

plot3(x,y,zeros(size(x)))

hold on

plot3(-x,-y,zeros(size(x)))

set(gca,'cameraposition',[0,0,1])

set(gca,'cameratarget',[10,0,0])

set(gca,'cameraviewangle',25)

xlabel('x')

ylabel('y')

Since I have asked this question twice and nobody has commented, I think it is safe to assume nobody knows or it is a bug nobody wants to talk about.

In that case, can anyone recommend if Octave handles camera view correctly? What about python?

Thanks

What version of Matlab are you running? And are you setting any other axis properties in other code? When I run your example, I get a different plot than you're seeing, one that appears to be correct (partial circle visible at bottom of view). I notice your plot has gridlines on, and that's not part of your code snippet above, so perhaps you set (or unset) some other properties somewhere?

Hello Kelly,

I am using r2012b. And I only ran the code you see immediately after clearing all and closing all. So it must be a version thing?

Which version do you have that gives a more correct view?

Thanks again.

R2017b view looks fine.
