Hi again,
This is similar to my previous answer.
In this case, I think here you are setting too many resources. Since
your X values are equally-spaced, you don't want to set the "sfXArray"
resource. Since your Y values are not equally-spaced, you don't
want to set the "sfYCStartV" and "sfYCEndV" resources.
With that in mind, remove the following lines from your code:
NhlRLSetFloat(srlist,NhlNsfYCStartV, 5);
NhlRLSetFloat(srlist,NhlNsfYCEndV, 21);
NhlRLSetIntegerArray(srlist,NhlNsfXArray, XArray, 5);
and try again.
