Dear All,
I am trying to make multiple plot (e.g. say 20) of a certain variable using
parea in a loop. I ran into problem shown below. I need your help.
=========
No hardcopy metafile open
All files closed; all defined objects released;
All GrADS attributes have been reinitialized
SET error: Missing or invalid arguments for PAREA option
Data Request Error: Invalid dimension expression
Attempt to set or modify varying dimension
Variable = loading.1, Dimension = 0
Error ocurred at column 1
DEFINE error: Invalid expression.
Syntax Error: Invalid Operand
'ho' not a variable or function name
Error ocurred at column 1
DISPLAY error: Invalid expression
Expression = ho
Hardcopy output file is closed
ga->
==========
My script is shown here:
'reinit'
'set map 1 1 6'
'set font 4'
'set mproj scaled'
*=======================
'sdfopen trial.nc'
'q file'
'set display color white'
'c'
'set grid off'
'set strmden 5'
'set lat 2.375 15.125'
'set lon 2.375 15.125'
'set mpdset hires'
*--------------------
'set xlab off'
*'set xlab on'
*'set xlevs 4 8 12'
*--------------------
'set ylab on'
'set ylevs 4 8 12'
'set grads off'
*-------------------------
dist_apart = 1.12
t1 = 0
row = 1
ylo = 7.08
yhi = 8.20
while(row<=1)
xlo = 0.42
xhi = 1.54
col = 1
while(col <= 1)
t1 = t1 + 1
*'set lat 2.375 15.125'
*'set lon 2.375 15.125'
'set parea 'xlo 'xhi' 'ylo' 'yhi'
'set t 't1
'define ho=loading.1(z=1,lon=2.375,lon=15.125,lat=2.375,lat=15.125)'
'set gxout shaded'
'd ho'
xlo = xhi
xhi = xhi + dist_apart
col = col + 1
endwhile
yhi = ylo
ylo = yhi - dist_apart
row = row + 1
endwhile
'close 1'
*'draw string 0.25 9.4 m'
*'run cbarn.gs 0.5 1 0.25 8.7'

Thank you,
