Surf z axis not visible

When i use surf (e.g. with peaks) the Z axis is not shown. (Linux 64, nvidia-drivers-295.49, Matlab 2012a)

[Jan]

Could you post a small example, which reproduces the problem?

[Kye Taylor]

What is the output from

which surf -all

[Florian]

example:

>> peaks

output:

>> which surf -all

Answer 1

[Florian]

Meanwhile I've noticed that it is visible in the exported eps. So that's good enough for me right now, though it is not a real solution to the problem...

Answer 2

[Kye Taylor]

After issuing

peaks

issue the command

zlabel('z')

[Florian]

not working... :(

[Kye Taylor]

Sounds like a more subtle problem... Perhaps try closing all figure windows first because zlabel will put a label on the current active figure window. If that doesn't work, does zlabel('z') add a zlabel on your machine with the following commands?

surf(membrane)

zlabel('z')

[Florian]

Same same and btw. it also appears right from the start, i.e. after I've restarted MATLAB.

I found that

>> axis vis3d

fixes it. BUT:

>> set(gca, 'DataAspectRatioMode', 'auto','PlotBoxAspectRatioMode', 'auto','CameraViewAngleMode', 'auto')

makes it disappear again. So how do I get both? Stretch to fill and a z axis?

[Kye Taylor]

You should be able to have both... The fact that surf(membrane) and zlabel('z') don't work right away is troubling, and I'm not sure what the solution is. I suggest posting a copy of your code that creates a figure that's 1.) missing the zlabel, 2) using axis vis3d to add a label, and 3.) using the set command to screw it up. Seeing all the commands sequentially may allow others more insight.

[Florian]

>> peaks

No z axis.

>> axis vis3d

Z axis visible

>> set(gca, 'DataAspectRatioMode', 'auto','PlotBoxAspectRatioMode', 'auto','CameraViewAngleMode', 'auto')

Z axis disappeared.

OpenGL renderer, right?

[Florian]

Yes!

>> set(gcf, 'Renderer', 'painters')

% zaxis visible

>> set(gcf, 'Renderer', 'zbuffer')

% zaxis visible

>> set(gcf, 'Renderer', 'opengl')

% zaxis NOT visible
