[ncl-talk] gsn_csm_contour, blank plot

[Ying Song]

Hi,  thanks for the reply!

The idea is plotting weekly profiles and I defined the array and everyweek,
I write one day data from input files and set other 6 days of the week as
missing values. I am not sure if that "ManualLevels" resources caused the
problem but even I commented them out, the plot is still blank.

I just added the stat_dispersion. below is the screen log when I run ncl
script:
