Hi Paulo,
The SHOW DATA command only goes and looks at the grid of the data. It
does not try to read any of the data; that happens only when you issue
a command which loads data, in this case the CONTOUR command.
You are missing the /COLUMNS qualifier on the file command, so when you
issue the CONTOUR command, only the firs column of each record is being
read.
In the section on reading ascii data, look at the example 4b) under Example 4—1 variable, 2
dimensions
4b) If
the file in the above example has, instead, 4 values per record:
3.1 2.6 5.4 4.6
3.5 6.1 . . .
then add
/COLUMNS=4 to the FILE command:
yes? FILE/VAR=height/COLUMNS=4/GRID=gplants greenhouse_plants.dat

Hi all,
I have a two dimensional one variable ascii file (matrix called
vel_amp1.dat). The file has the following dimensions (901 lines x 1081
columns). Following manual I did the following
*************************************
DEFINE AXIS/X=1:1081:1 xlon
DEFINE AXIS/Y=1:901:1 ylat
DEFINE GRID/X=xlon/Y=ylat vel_amp
FILE/VAR=height/GRID=vel_amp vel_amp1.dat
**********************************************
When I execute the show data command I got the following:
*************************************************************************
currently SET data sets:
1> .\vel_amp1.dat (default)
name title I J
K L
HEIGHT HEIGHT 1:1081 1:901 ... ...
**************************************************************************
When tried to contour the height variable I've got the following error
message:
CONTOUR height
**********************************************************************************
yes? contour height
**ERROR: dimensions improperly specified: must be a 2D region
contour height
***********************************************************************************
What am I doing wrong?
Thanks for the help,
Luiz
