Dear Users,
                              I have modified the script spec_3.ncl
which is from http://www.ncl.ucar.edu/Applications/Scripts/spec_3.ncl
to suite the attached data bps_iso_box.nc and obtained the attached
figure.
But I have the below questions on this
1) the original script was for monthly data and the xaxis is coming as
cycles/month can ncl take care of the time axis? ie my in put data is
daily so does ncl recognise this and do the need full so that if I
simply change the x axis title will the plot be correct? or do I need
to change some where in library and make ncl know that I am imputing
daily data?

2) The confidence level looks some thing odd (to me) do I need to
modify some where so that the confidence level will be computed as per
my input data?
kindly answer the above 2 questions if any one used these excellent
functions earlier.

-- 
with best regards
Sudheer
