.SH NAME
xpolys - draw a set of polylines or polygons
.SH CALLING SEQUENCE
.nf
xpolys(xpols,ypols,[draw])
.fi
.SH PARAMETERS
.TP 13
xpols,ypols
: matrices of the same size (p,n) (points of the polylines).
.TP
draw
: vector of size n.
.SH DESCRIPTION
\fVxpolys\fR draws a set of polylinse using marks or dashed lines.
The coordinates of each polyline
are stored in a column of \fVxpols\fR and \fVypols\fR.
.LP
The style of polyline i is given by \fVdraw(i)\fR:
.TP 3
-
If \fVdraw(i)\fR is negative, the mark with id \fV-draw(i)\fR is used to
draw polyline i (marks are drawn using the current pattern).
Use \fVxset()\fR to see the meaning of the ids.
.TP
-
If \fVdraw(i)\fR is strictly positive, the line style (or color) with id
\fVabs(draw(i))\fR is used to draw polyline i.
Use \fVxset()\fR to see the meaning of the ids.
