plsvect
( | arrowx, |
| arrowy, | |
| npts, | |
fill); |
Set the style for the arrow used by plvect to plot vectors.
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
and
arrowx are NULL then
the arrow style will be reset to its default.
arrowy
npts
(PLINT,input)
Number of points in the arrays
and
arrowx.
arrowy
fill
(PLBOOL,input)
If is true then the
arrow is closed, if fill
is false then the arrow is open.
fill
Redacted form: plsvect(arrowx, arrowy, fill)
This function is used in example 22.
