[ncl-talk] taylor_diagram question

[Tao Zhang]

Hi,

  I can reproduce the taylor_4 figure using the sample script in

https://www.ncl.ucar.edu/Applications/Images/taylor_4_1_lg.png

https://www.ncl.ucar.edu/Applications/Scripts/taylor_4.ncl

But I want  Figure 1 in

https://en.wikipedia.org/wiki/Taylor_diagram#:~:text=Taylor%20diagrams%20are%20mathematical%20diagrams,comparative%20assessment%20of%20different%20models

Which shows the standard deviation (0~4 mm/day), not the standardized 
deviations (normalized) (0-1.5).

1) May I only change the taylor_4.ncl for my purpose, but keep the 
loaded "taylor_diagram.ncl" unchanged?

2) How to add "observed value" in the Taylor diagram as shown in Figure 
1 in above link?

3) How to change the color in 3 lines of standard deviation, 
correlation, and RMS?

Thanks

Tao
