[ferret_users] how to modify axis attributes
Hi ferreters,
I am trying to modify the attributes of axes and cannot get it working.
To demonstrate the problem consider the following short script:
____
use monthly_navy_winds.cdf
let t2 =2*UWND
SET ATT/OUTPUT (`t2,return=xaxis`).point_spacing = "uneven"
save/clobber/file=dummy.nc/l=1 t2
____
The x-axis of uwnd has the attribute
FNOCX:point_spacing = "even" ;
I would like to have it changed to uneven, whatever the reason is ...
After setting the attribute ferret answers
!-> SET ATT/OUTPUT (FNOCX).point_spacing = "uneven"
Fine. However, after saving and inspecting the outputfile with ncdump,
one finds
FNOCX:point_spacing = "even" ;
What happens here?
Another question to the same problem:
How to define a new axis attribute?
DEFINE ATT/OUTPUT (`t2,return=xaxis`).new_att = "somthing"
produces the answer
!-> DEFINE ATT/OUTPUT (FNOCX).new_att = "somthing"
but nothing is in the output?
Greetings,
Martin
