# plsvect(3plplot)

Set arrow style for vector plots

## 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)](/plvect/3plplot.md) to plot vectors.

Redacted form: **plsvect(arrowx, arrowy, fill)**

This function is used in example 22.

## ARGUMENTS

- *arrowx, arrowy* (**PLFLT\_VECTOR**(3plplot), input)

  A pair of vectors 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**(3plplot), input)

  Number of points in the vectors *arrowx* and *arrowy*.

- *fill* (**PLBOOL**(3plplot), input)

  If *fill* is true then the arrow is closed, if *fill* is false then the arrow is open.
