[ncl-talk] significance

[Alan Brammer]

Not entirely clear what the problem is in your email.  You seem to have presented both the intended outcome and the solution.  

It is however noted on the NCL documentation of ShadeLtContour that it has been superceeded by gsn_contour_shade. That may have more flexibility for your intended results. 

Or are you asking on peoples preferences of shading the significant or the insignificant area of a plot?  If that’s the case, then I don’t think there is a standard and it is personal preference.

Subject:  [ncl-talk] significance

Dear all,

I calculated the correlation SST between  2 different models and also the r test (significance), and now I need to plot a map with the correlation and the significant part of the 95% stippled.

I used the example  http://www.ncl.ucar.edu/Applications/Scripts/conOncon_4.ncl
but, this example is plotted:   shade all areas less than the  0.05 contour level

in my case, I would have to use   Shade  Gt  Contour  or   ShadeL  t  Contour, and 0,95 ? Can someone help me?

                                 plot2   = gsn_csm_contour(wks,gsn_add_cyclic_point(rsig(:,:,0)), res2)  
plot2   = ShadeGt
                                    Contour(plot2, 0.95,
                                     17)
