[gradsusr] Misaligned plot

[Ipshita Majhi]

Dear Grads,

I created a descriptor file to read a netcdf file using xdfopen. I created
two three kind of descriptor file but when I plot it the data looks very
shifted.
I don't where I am going wrong.

DSET ^sce_mon_mean.nc
TITLE This is a sample
UNDEF  -9.99e+08
XDEF x 88 LINEAR -180 4.09090909
YDEF y 88 LINEAR 0.0 1
TDEF time 573 LINEAR OCT1966 1MO
VARS 1
sce=>sce 0 1 Snow cover extent
ENDVARS

The nudump -h looks like this

dimensions:
x = 88 ;
y = 88 ;
time = UNLIMITED ; // (573 currently)
variables:
double time(time) ;
time:standard_name = "time" ;
time:long_name = "time" ;
time:units = "days since 1966-10-03 00:00:00" ;
time:calendar = "standard" ;
byte sce(time, y, x) ;
sce:standard_name = "surface_snow_binary_mask" ;
sce:long_name = "NOAA/NCDC Climate Data Record of snow cover extent" ;
sce:_FillValue = -9b ;
sce:missing_value = -9b ;
sce:flag_meanings = "no_snow snow_covered" ;

// global attributes:
:CDI = "Climate Data Interface version 1.6.2 (
http://code.zmaw.de/projects/cdi)" ;
:Conventions = "CF-1.4" ;
:history = "Mon Sep 15 23:25:22 2014: cdo monmean sce.nc sce_mon_mean.nc" ;
:CDO = "Climate Data Operators version 1.6.2 (
http://code.zmaw.de/projects/cdo)" ;
}
