NAME

       plsvect - Set arrow style for vector plots

SYNOPSIS

       plsvect(arrowx, arrowy, npts, fill)

DESCRIPTION

       Set the style for the arrow used by plvect(3plplot) to plot vectors.

       Redacted form: plsvect(arrowx, arrowy, fill)

       This function is used in example 22.

ARGUMENTS

       arrowx, arrowy (const PLFLT *,input)
              Pointers  to  a pair of arrays containing the x and y points which make up the arrow. The arrow is
              plotted by joining these points to form a polygon. The scaling assumes that the x and y points  in
              the  arrow lie in the range -0.5 <= x,y <= 0.5. If both  arrowx and arrowy are NULL then the arrow
              style will be reset to its default.

       npts (PLINT,input)
              Number of points in the arrays arrowx and arrowy.

       fill (PLBOOL,input)
              If fill is true then the arrow is closed, if fill is false then the arrow is open.
