Re: [ferret_users] time series labels

I will just add that @ASN requires care and cross-checking, because  
you CAN produce an invisibly-erroneous plot this way. @ASN forces the  
new axis whether or not it is consistent with the actual data . One  
of Ferret's advantages is that by reading the axis information out of  
the netcdf file, it is hard to make such a mistake. @ASN turns that  
information into a simple index list, and the wrong choice will give  
an unseen error. Just like sudo, you can do a lot of damage if you're  
not careful!
