Dear Jie Tang,

To modify the axes, use the special "tr" resources (TRansform):

   res@trXMinF = -200
   res@trXMaxF = 200
   res@trYMinF = -200
   res@trYMaxF = 200

You can learn more about customizing your XY plots by looking at the following example page:

Example 5 (xy_5.ncl) talks about trYMinF and trYMaxF.
