[ncl-talk] unable to plot correctly

Wed Aug 1 12:18:43 MDT 2018

thanks Dennis. I have to plot the count value only which is between 0-1001. (MinMax MIR). the plotting is over but the plot shows small white dots and is fully black on careful examination. I could not understand why should that be (i mean black with white dots) because below the plot, it is shown "Contour from 0-1001". 
If I ON the contour resources, the code runs forever. 

thanks Geeta.

 I think this has been mentioned to you before:

The 2nd-most important rule is read the documentation of the project.

Note: It is not ncl-talk's job to read the documentation. It is your job.

I speculate that to get correct values you would have to use something like:

   MIRF = MIR*MIR at lab_radiance_scale_factor + MIR at lab_radiance_add_offset

or

   MIRF = (MIR + MIR at lab_radiance_add_offset)*MIR at lab_radiance_scale_factor

or

   ????

Again, this is your responsibility.

Good Luck

Hi all. I am trying to plot MIR_int (variable defined in the ncl code), but it is not being plotted properly. the output is without any error
