[gradsusr] displaying 2 variables

[Jennifer M Adams]

The lev value set for the first data file doesn’t match the lev value in the second file, so you need to add a dimension override. Use this instead for your second display:
d hgt.2(t=1,z=1)

Dear Grads users,

I am facing a problem in displaying two variables together, temperature in shades and geopotential height in contours.
Please guide me. Detail is given here.
Thanks
Amina


file 1 is temperature.nc
LON set to 0 360
LAT set to -90 90
LEV set to 0 0
Time values set: 2007:4:15:0 2007:4:15:0
E set to 1 1

file 2 is hgt.nc
LON set to 0 360
LAT set to -90 90
LEV set to 500 500
Time values set: 2007:4:15:18 2007:4:15:18
E set to 1 1

I used the following commands;
sdfopen temperature.nc
sdfopen hgt.nc
set gxout shaded
d air(t=1)
set gxout contour
d hgt.2(t=1)

But this error appears..
Data Request Warning:  Request is completely outside file limits
  Entire grid contents are set to missing data
  Grid limits of file:     X = 1 144  Y = 1 73  Z = 1 1  T = 1 1  E = 1 1
  Grid limits of request:  X = 1 144  Y = 1 73  Z = -499 -499  T = 1 1 E = 1 1
  Warning issued for variable = hgt.2
