[ncl-talk] Plotting output of Mann-Kendall test(trend manken)

The resources gsnDraw and gsnFrame should both be True (or commented out, since the default is True).

You only need to set them to False if you’re going to make adjustments after plotting, for example making a panel plot, adding a polyline or an overlay.

If you do set them to False, you must still tell NCL to draw and frame after plotting, so the last lines of your script would be:

draw(plot)
frame(wks)

Subject: [ncl-talk] Plotting output of Mann-Kendall test(trend manken)

Dear fellow NCL-users,

I am trying to perform a mann-kendall trend test on CMAP monthly rainfall. I am using NCL v6.4.

Attached is my script. The data can be accessed in the following link:

https://drive.google.com/file/d/0B9faET7Bc2o8YTVEc3JXWFRRNk0/view?usp=sharing

The script returns no error , a netcdf file is created, but no png file is created.
I also cannot open the output netcdf file even in GrADS (No discernible coordinate issue).

I wanted to plot a spatial map of the probability level.


I think my problem is this line?
plot = gsn_csm_contour_map(wks,pq(0,:,:),res)

Is this the correct way of just plotting the probability level?

I'll appreciate any suggestion on how to do this correctly.

Sincerely,

Lyndz
