Hi,

When I plot 3D data with large xyz values, the "Move Camera Forward/Back" button on the Camera toolbar does not work. However, when I manually change the CameraPosition property in the Command Window, it adjusts the camera position fine. I understand that the axes are very large, but it is simply the nature of the data I am working with. Any ideas on how to fix this issue?

Example code:
[x,y] = meshgrid([-1e6:10000:1e6],[-1e6:10000:1e6]);
surf(x,y,abs(x)+abs(y));
cameratoolbar;

I am doing the following to manually change the camera position:
set(gca,'cameraposition',.9*get(gca,'cameraposition'))

Thanks,
John

I think I found my issue in cameratoolbar.m. MATLAB is setting a maximum and minimum distance when using "camera move forward/back"
