[ncl-talk] doubt if data is being plottted

[Geeta Geeta]

Thanks Mary for your valuable support. I really acknowledge that. The plot looks different and I could see the Deep Blue Dot too. Pls check from line no 5784 and around this (52.05)
My question is that around this point there were non-zero values, so why gsn_countour_map is missing some of the data points. and what method of filling the contours is used by "cnFillOn = True"  . I have attached my output with this. I am also sending the data at your ftp address. 
My data looks complete now because I can see each and every pixel. 
 warm regardsGeeta.

 Geeta,
We cannot debug this by simply looking at data values and plots. I do see the issue that you are pointing out, but without seeing your code, I can't be sure of the problem.
If your value that is 52.05 is surrounded by missing values, then I think it's possible it won't show up on the plot. You could try doing a raster plot:
res at cnFillMode = "RasterFill"
to see if this changes anything.
If it doesn't, then if you could provide the data and a clean script, this would really help.
thanks,

dear ncl-talkI am using a variable called Z_fnl which is filtered for one condition and the it is called maxZ. Then maxZ is filtered for 2 conditions and is called maxZ_Conv. 
Below output is the LIne number ofthe file, Raintype, Lat, Lon, maxZ, maxZ_Conv (Output is attatched)    5843 (118,0) -9999 14.7402 75.7023   0    -9999   5844 (118,1) 152 14.7826 75.6777   23.09    -9999   5845 (118,2) 210 14.8249 75.6531   34.03    34.03   5846 (118,3) 200 14.8669 75.6286   52.05    52.05   5847 (118,4) 200 14.9083 75.6044   40.67    40.67   5848 (118,5) 210 14.9496 75.5802   22.34    22.34   5849 (118,6) 120 14.9906 75.5562   23.75    -9999   5850 (118,7) 210 15.0313 75.5322   24.61    24.61   5851 (118,8) 210 15.0716 75.5085   36.33    36.33   5852 (118,9) 210 15.112 75.4847   42.3    42.3Now I am plotting the Raintype and maxZ_Conv for a small area and for a large area. 
Now my problem is that it looks like that the plots and unable to correspond directly to the data. For example, in the line number at 5846 which has highest value of 52.05 at the point 14.8669/75.6286 . Pls also check the lines from 5843-5852. 
 (118,3) 200 14.8669 75.6286   52.05    52.05 seems to be missing in the plot. At this point the DEEP Blue color is missing. 
I m sorry for asking this basic question.
