Why does the function streamslice not work when I define the X and Y axes

Hello,

I am trying to plot streamlines for a 2-Dimensional vector field. When I do not define the X and Y axes the streamslice function works properly (i.e. streamslice(U,V).

When I try to use the same function together with the original X and Y axes the function returns an empty plot with axis going from 0 to 1. (i.e. streamslice(X,Y,U,V).

X,Y,U and V are all the same size and X, and Y are formed by using meshgrid. Furthermore they are monotonic.

No error message is displayed, the streamlines are simply not drawn.

Anyone knows how to resolve this issue?
