questions regarding Taylor diagram scripts

Hi.

  How can I have RMS values appear on the RMS cycles?

  How can I turn on/off the numbers that appear with each point plotted on
the diagram?

  Lastly, how can I make some of the point labels into strings ( e.g...one
point says NNRP2 whereas another point nearby says MERRA?)

Can all of this be solved with makeing changes in the required
taylor_diagram.ncl script or can thye be solved using the interface script
(below)?

Below is the script I used to make the following picture.
Basically, I want to keep the red numbers as they are (or make them
disappear), but put labels on the blue green and orange points instead of
numbers.

Any tips? Thank you ahead of time.
Sincerely,
Erik
