Re: how to use "time_axis_labels"?

hi Basit,
 make sure that the 0th argument to time_axis_label() is an 1-d array
containing the 'time' values as numbers. The numbers must have been
calculated from a origin with a proper units, specified by the "units"
attribute to the 0th argument. In your case, please make sure that
'newdate' is a numerical variable and not a string, and has a units
attribute something of this form: "days since yyyy-mm-dd hh:mm:ss". Check
cd_inv_calendar() for more details about this "units" attribute.

regards,
