Re: time series plot appearance problem

[Billy Kessler <William.S.Kessler@xxxxxxxx>]

If the time axis is climatological (i.e. modulo), then plot from l=11 through l=25,
and use the time command to restrict the range actually plotted:

fill/set/l=11:25 variable_name
ppl time,w000201010000,w000212310000
ppl txlint,1,0    ! get month labels only
ppl fill
