  • vvectr(3NCARG)Manages the coordinate system mapping, color setting, auxiliary text output, and drawing of the vector field plot, according to the specifications established by the parameter setting routines and…✨
  • vvgetc(3NCARG)Gets the current value of a Vectors parameter of type CHARACTER.✨
  • vvgeti(3NCARG)Gets the current value of a Vectors parameter of type INTEGER.✨
  • vvgetr(3NCARG)Gets the current value of a Vectors parameter of type REAL.✨
  • vvinit(3NCARG)Performs initialization tasks required before VVECTR may be called to plot a vector field, including copying array size information into internal common block variables, establishing coordinate…✨
  • vvrset(3NCARG)Resets all parameters to their initial default values.✨
  • vvsetc(3NCARG)Sets the value of a Vectors parameter of type CHARACTER.✨
