Re: Taylor diagram - about "ratio", "Standardized Deviations (Normalized)"

Thanks, Dennis

 But,
 On the same page, http://www.ncl.ucar.edu/Applications/taylor.shtml
  Look example 1:
      In its script, i do not find lines that process ratio (ratio of the
standardized variances) to Standardized Deviations. The YAxis is set in
taylor_diagram.ncl , so figure 1 use "Standardized Deviations
(Normalized)" as YAxis.

Other examples also like this.

thanks
Ning
