These functions create very generic vector plots.
We recommend that you use the more customized functions:
gsn_csm_vector
gsn_csm_vector_map
for creating vector plots.
See the "vectors" examples page for more customized vector plots.
gsn_vector_1.ncl: Default plot
gsn_vector is the generic plot interface that creates vector 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 vector.
gsn_vector_2.ncl:
Colors the vectors by their magnitude and adds a label bar.
vcMonoLineArrowColor = False, colors the vectors by their magnitude.
pmLabelBarDisplayMode = "Always", turns on label bar.
lbPerimOn = False, turns off label bar perimeter box
pmLabelBarWidthF = 0.4, controls the size of label bar
