[ncl-talk] Missing grid lines at zero degree

Hi there,
Somehow I get a gap along the zero degree while plot polar region plus using gsn_coordinates to plot grid lat/lon lines.
Is there any way to fill that gap?
The code that I use to plot the grid lines:
;---Data and grid read in:
mskFile = addfile("access.n96.newu2.nc","r")
vTemp = rm_single_dims(mskFile->NEWVAR2(0,0,:,::2))
vMTemp = vTemp
;---Call function to attach lat/lon lines.
pres = True
pres at gsnCoordsAsLines = True ; Default is points
pres at gsLineThicknessF = .1
pres at gsLineColor = "Gray25"
pres at gsnCoordsAttach = True
gsn_coordinates(wks,plot1,vMTemp,pres)
The input file information:
;---Ncdump the netcdf file:
dimensions:
LONGITUDE = 192 ;
LATITUDE_1 = 144 ;
HYBRID_HT = 85 ;
variables:
double LONGITUDE(LONGITUDE) ;
LONGITUDE:units = "degrees_east" ;
LONGITUDE:point_spacing = "even" ;
LONGITUDE:modulo = " " ;
LONGITUDE:axis = "X" ;
double LATITUDE_1(LATITUDE_1) ;
LATITUDE_1:units = "degrees_north" ;
LATITUDE_1:point_spacing = "even" ;
LATITUDE_1:axis = "Y" ;
float NEWVAR2(T, HYBRID_HT, LATITUDE_1, LONGITUDE) ;
NEWVAR2:missing_value = -1.e+34f ;
NEWVAR2:_FillValue = -1.e+34f ;
NEWVAR2:long_name = "U[G=NEW_GRID]" ;
NEWVAR2:history = "From access.n96.uv" ;
Regards,
Arnold
