[ncl-talk] Multiple Issues

[Jinwoong Yoo]

Thank you, Dave, for your reply.


Data that I'm plotting is difAve which is overlaid by prob.


Variable: difAve
Type: double
Total Size: 4629312 bytes
            578664 values
Number of Dimensions: 3
Dimensions and sizes: [lat | 171] x [lon | 282] x [month | 12]
Coordinates:
            lat: [-13.06634..47.43503]
            lon: [94.46107..205.5389]
            month: [0..11]
Number Of Attributes: 2
  units : m/s
  long_name : LGM-Modern


Variable: prob

Summaries for lat and lon are as below:

Variable: lat

  cell_methods : time: mean
  FieldType : 104
  MemoryOrder : XY
  description : LATITUDE, SOUTH IS NEGATIVE
  units : degrees_north
  stagger :
  _FillValue : 9.96921e+36

Variable: lon
Type: float
Total Size: 1128 bytes
            282 values
Number of Dimensions: 1
Dimensions and sizes: [south_north | 282]

Thank you very much!

The unwanted lines in your plot all seem to be pointing towards a single point. Perhaps an issue with a missing value not being recognized properly?
It might help us diagnose the problem if you printed out summaries of the lat, lon, and data variables.

Have you tried doing what the error suggests?

(0) You may want to set the gsnAddCyclic resource to False to avoid a
(0) warning message from the spline function.

if your plotting resources are in a variable name res

res at gsnAddCyclic  = False

Dear NCL users,

I am trying to plot an image following an example at https://www.ncl.ucar.edu/Applications/Images/climo_1_lg.png.<https://www.ncl.ucar.edu/Applications/Images/climo_1_lg.png>
[https://www.ncl.ucar.edu/Applications/Images/climo_1_lg.png]

but I'm getting a few warnings and my result plot is not pretty enough (attached).

Warning messages are as below:

(0) gsn_add_cyclic: Warning: The range of your longitude data is not 360.
(0) You may want to set the gsnAddCyclic resource to False to avoid a
(0) warning message from the spline function.
warning:_NhlCreateSplineCoordApprox: Attempt to create spline approximation for X axis failed: consider adjusting trXTensionF value
warning:IrTransInitialize: error creating spline approximation for trXCoordPoints; defaulting to linear
