Display map near 180deg E/W

Hi,

I am trynig to display a trajectory plot near the location of 180deg E/W.
However as seen from the attached plot, the trajectories are all around the
+-180deg location. Some trajectories are in the 179deg E, while some are at
the 179deg W. I would like to zoom up into the location the trajectories are
in.

I used :

res@mpMinLatF = -1+(min(min_y))
res@mpMaxLatF = 1+(max(max_y))
res@mpMinLonF = -1+(min(min_x)) ;some allowance
res@mpMaxLonF = 1+(max(max_x))

but it can't work.

Do you have any solution?

Thank you very much.

Regards
