NhlDataPolygon

The Fortran name of this function is NhlFDataPolygon.

Given arrays containing the X and Y coordinates of points in data coordinate space, this function outputs an immediate-mode polygon connecting each of the points.

Fortran Synopsis

      subroutine NhlFDataPolygon(pid, gsid, x, y, n, ierr)
      integer pid, gsid, n, ierr
      real x(n), y(n)

Arguments

pid (input): Id of a Transform or Workstation object.
gsid (input): Id of a GraphicStyle object.
x (input): Array of X-Axis coordinate values in data coordinate space.
y (input): Array of Y-Axis coordinate values in data coordinate space.
n (input): Number of elements in the coordinate arrays x and y.
ierr (output, Fortran only): Error code.
