vector plots in stereographic projection

["Bernadette Fritzsch" <fritzsch@xxxxxxxxxxxxxxxxxx>]

Hallo,

i have some data which i want to plot in stereographic projections.

My script looks like

go mp_stereographic_north
set region/y=50n:90n
set grid thick
contour /lev=(0,5,1) thick ,x_page,y_page

set grid u
vector u,v,x_page,y_page

The first works well, the second does not. WHy?

Any suggestions?

Thanks.
