I'll try to explain:
1. you can check the viewpoint property of the axes. Disadvantage:
even if it is 3-d data, once the viewpoint becomes 2d (i.e. looking
from above the x-y plane), you will not be able to rotate using mouse
2. you can check and see if the actual data lies on a plane (x,y,z
data property of the axes, and also the auto calculated axis limits).
Disadvantage: maybe someone would want to rotate 2d data
