DISPLAY SINGLE VALUE

[Emily]

Hi Piotr,

Try this script that I found from Grads20 a2.3, it may help you. 
============
*  Plots a string using current attributes
*  at "clicked on" position.  String can be provided
*  as an argument or will be prompted for 
*
function string (args)
  if (args='') 
    say 'Enter string:'
    pull args
  endif
  say 'Click where you want the string'
  'query bpos'
  x = subwrd(result,3)
  y = subwrd(result,4)
  'draw string 'x' 'y' 'args
=============================

Hi, the gxout grid command is useless for my purpose because it just give to me the value in the grid point coordinate. If I want the value for a point that is, let's say, to the right or to the left  or between two grids points How can I deploy this single value on a map?




Set Lat,Lon to specific value ie.

'set lat 51'
'set lon 17'

then

'define t2 = tmp2m-273.15'
'q defval t2 1 1'
TMP=subwrd(result,3)

say TMP
