Hi guys, I run the fellowing code with windows IDL 8.2: ; Read the data. RESTORE, FILEPATH('globalwinds.dat', SUBDIR=['examples','data']) mp_bg = MAP('Stereographic', $ CENTER_LONGITUDE=110, $ CENTER_LATITUDE=90) vec = vector(u, v, x, y, /overplot, GRID_UNITS=2) But there is a blank area between 60W to 180W. So why?

It looks like your center_longitude isn't correct. Try the following: mp_bg = MAP('Stereographic', $ CENTER_LONGITUDE=0, $ CENTER_LATITUDE=90)

So center_longitude must be set to 0
