[gradsusr] ploting problems

[kombo kai]

Hi Grads use
I Have created a variable called the envifomental vertical windshear as folows
'sdfopen d:/vorticity/uwnd.mon.mean.nc'
'sdfopen d:/vorticity/vwnd.mon.mean.nc'
'set lon 0 360'
'set lat -90 90'
'set t 1 778'
'set z 10'
'define U1=uwnd(z=10)'
'define V1=vwnd.2(z=10)'
'set z 3'
'define U2=uwnd(z=3)'
'define V2=vwnd.2(z=2)'
'define U=U1-U2'
'define V=V1-V2'
'define evws28=sqrt(U*U+V*V)'
'set sdfwrite d:/EVWSdata/evws_200-850.nc'
'sdfwrite evws28'

when I opened the file I created it gives me al the dtaile for the file , but I do the following settings it plots onlt from 0-120 abd do not plot the -70 to 0E
eg set t 34
set lon -70 120
set lat -45 45
set gxout contour
set cint 19
set ccolor 2
set cmark 2
d evws28
This plot only from 0 120E and do not plot from -70 to 0E
Please I need a help to fix this problem 
regards
kaikombo
