axis label

[benb <benb@xxxxxxxxxxxx>]

Hello All,

I read in 48 points of data from a netCDF file:
set data airtemp.nc

and then I'm using the following script to create a plot of the data:

DEFINE AXIS/t="1-OCT-2002:00:30":"2-OCT-2002:00:00":30/UNITS=minutes my_taxis
let tseq_air_temp = tsequence(Air_Temperature)
let tax_air_temp = tseq_air_temp[gt=my_taxis@asn]
let Air_Temperature_Kelvin = tax_air_temp
let Air_Temp = Air_Temperature_Kelvin

plot/set_up/nolabel Air_Temp
ppl title "Air Temperature - Diurnal Cycle"
ppl xlab "Time"
ppl ylab "Celsius"
ppl plot


It may be more complex than needed, but it works.  However, the x axis is la
belled with both hours and date, i.e.:

00  01  02  03  .  .  .  22  23  00
           Oct 1


I want to keep only the hours ("00  01  02  03  .  .  .  22  23  00", an ano
nymous 24 hour sequence) and get rid of the "Oct 1" part.  Can someone tell 
me how to do that?

I tried xlab as both
ppl xlab"Date, Time"
and 
ppl xlab "Time" but they both gave me the same results.

Thank you,

Ben
