NCL Graphics: Vector over Scalars (generic high-level plot interfaces)

Vector over Scalar Type Plot Templates

gsn_vector_scalar
gsn_vector_scalar_map

These functions create very generic vector/scalar plots.

We recommend that you use the more customized functions:

gsn_csm_vector_scalar
gsn_csm_vector_scalar_map

for creating vector/scalar plots.

See the "vectors" examples page for more customized vector plots.

gsn_vec_scal_1.ncl: Vectors colored by a scalar field.

gsn_vector_scalar is the generic plot interface that creates vector scalar plots.

vcRefMagnitudeF = 15.0, Defines the reference vector magnitude. Use this to adjust the size of the vectors.

vcRefLengthF = 0.045, Defines the length of the reference vectors.

gsn_vec_scal_2.ncl: Creates a contour plot and a separate vector plot and then overlays them.

gsn_vector is the generic plot interface that creates vector plots.

gsn_contour is the generic plot interface that creates contour plots.

See gsn_contour_3.ncl for how to add a colorbar to this plot.

gsn_vec_scal_3.ncl: Vectors colored by a scalar field and overlaid on a map.

gsn_vector_scalar_map is the generic plot interface that creates vector plots over the cylindrical equidistant map projection..
