Re: axis label
Hi Ben,
You can use PPLUS commands "TXLINT" to get rid of the
day label from the time axis. The usage is
TXLINT,low_int,hi_int
Low_int = labeling interval for lowest level of tics (e.g. hr on hr/day axis)
Hi_int = labeling interval for highest level of tics (e.g. day on hr/day axis)
Have a look at the manual for all PPLUS commands for time axis :
Ch6 Sec3.2. PPLUS axis commands
This is a good mail in the archive regarding your question :
http://ferret.pmel.noaa.gov/Ferret/Mail_Archives/fu_98/msg00090.html
Have a trial with the example below
Few comments :
1. use "set var" command to assign proper title and units for the
newly defined variable, especially if you are choosing the
default labels/saving the variable to a new NetCDF file.
(see the example below)
2. " PPL XLAB " will be ignored if TAXIS is on. See the example
below to do the labelling of time axis.
3. No need to define a number of variables without any use :
try ==> Air_Temp = tseq_air_temp[gt=my_taxis@asn]
Hope This Helps
With Regards
Jaison
