Hi Eilert,
        For a dataset with certain projection, you can call a grid formula to 
flip the grid to (-180 180) and display the streamlines in the area centered on 
zero meridan. I tried the dataset 


and it works. You can do it this way:


Formula > Grids > Define a grid diagnostic, and select the vector display, when 
a window popup,  type in lonFlip(a), when a new window popup, select vector
