[ncl-talk] Regional plot instead of global plot

[Mark Chan]

 Dear Adam,
In the script you can see as below:  copy_VarCoords(u, ur )  printVarSummary(ur)  printVarSummary(u)
However, the print message show diffference for ur and u (orginal variable). As you said that the coordinate info was not correct for the plot. Can you give more suggestion? 
Variable: urType: floatTotal Size: 227900 bytes            56975 valuesNumber of Dimensions: 2Dimensions and sizes: [y | 215] x [x | 265]Coordinates: Number Of Attributes: 3  units : m s-1  long_name : Zonal Rotational Wind  _FillValue : -2.147484e+09

 Hi Mark,Nothing stands out in your script to me. That likely means that there is something amiss with the coordinate variables attached to the arrays that are being passed into the plotting function. Examine the ur/vr arrays with printVarSummary statements and set things accordingly. If you cannot solve the issue, please respond back to ncl-talk with any error messages along with the print outs from any printVarSummary statements. Adam

Dear NCL group.
The attached files are NCL script and its plot. Actually the netCDF data is for a specific domain on earth, instead of global data. Why do the attached NCL script make the global plot? Can one give a suggestion to make plot based on the area of the original data?
Thanks a lot in advanceMark_______________________________________________
