Hi Timmy - It's normal, since your vector field has a non-zero 
x-component, which leads to a bounding box that expands along the x-axis 
in "displacement" mode. (Change the "Displacement factor" to see how the 
bounding box behaves when you change the displacement amplification.)

You can force the size of the axes by unselecting "Automatic 3D
positioning" in the "Aspect" option panel.

Take care,

Christophe
