[ncl-talk] About specify color of specific places, when do contour plotting

[Tao Lu]

Dear ncl-talk

I have some data like this:
about rain density 0.0 ~ 409.0 mm/h step 0.1 mm/h
integer number rain density
0 0.1 mm/h less then
1 0.1 mm/h
2 0.3 mm/h
  .
  .
4089 409.0 mm/h
4090 409.0 mm/h more then
4091 out of the obsevation region
4092 not observed

I define rain density in this way:
    if data_rain_integer == 4090:
        rain_density = 500
    elif data_rain_integer == 4091:
        rain_density = -1000
    elif data_rain_integer == 4092:
        rain_density = -999
    else:
        rain_density = data_rain_integer*0.1

Do you know how to specify not observed data as black color when I plot
rain density contour?

Yours sincerely,
Tao
