Re: [Cdat-discussion] Define time axis with cdtime?

[Hayes, W. <bh...@ca...>]

Hi Sudipta,
I've only worked with monthly data, but I believe
for your daily data you would do something like:

Assuming the number of days was 4000 (you'll have to calculate this):

days_list = range(4000)
ta = cdms2.createAxis( days_list )
ta.id = 'time'
ta.units = 'days since 2004-10-01'
var.setAxis(0, ta)
cdutil.setTimeBoundsDaily(var, 1 )  # 1 is daily frequency, assumes 1 data
pt per day
