[ferret_users] extracting info from axes
Hi Ferret Users,
Apology if this request is too elementary.
I would like to extract grid info from a data set for the purpose of
labeling. For example, for a given region/i=242/j=14/k=22/l=8, I have the
lon, lat, z, and time as follows:
yes? list x[gx=xt_ocean]
VARIABLE : X
axis XT_OCEAN
LONGITUDE: 38.5W(-38.5)
-38.50
yes? list y[gy=yt_ocean]
VARIABLE : Y
axis YT_OCEAN
LATITUDE : 68.5S
-68.50
yes? list z[gz=zt_ocean]
VARIABLE : Z
axis ZT_OCEAN
DEPTH (m): 215
215.0
yes? list t[gt=TIME]
VARIABLE : T
axis TIME
TIME : 07-FEB-1999 12:00 JULIAN
2228.
I would like to define a label, which should be something like
"38.5W, 68.5S, DEPTH (m): 215, 07-FEB-1999"
Of cause, it will be different for a different region if I change i,j,k,
or l values.
Is it a way to create the label dynamically?
Thanks,
--- Peng
