.SH NAME
xpolys - draw a set of polylines
.SH CALLING SEQUENCE
.nf
[]=xpolys(xpols,ypols,[draw])
.fi
.SH PARAMETERS
.TP 15
xpols, ypols
: matrices of size (p,n)
.TP
draw
: vector of size n
.SH DESCRIPTION
Draws a set of polyline using marks or dashed lines, each polyline points
are store in a column of \fVxpols, ypols\fR. \fVxpols =[ xpol1;xpol2;...] '\fR
.LP
The style is given by \fVdraw\fR :
.PP
If \fVdraw(i)\fR is negative the mark of id \fV-draw(i)\fR is used to
draw the polyline i ( marks are draw using the current pattern)
.PP
If \fVdraw(i)\fR is strictly positive the line style (or color) of id \fVabs(draw(i))\fR is used to draw the
polyline i.
.LP
.SH EXAMPLES
.nf
plot2d(0,0,[-1],"012"," ",[0,0,1,1]);
rand('uniform');
xset('pattern',3)
xpolys(rand(3,5),rand(3,5),[-1,-2,0,1,2])
xset('default')
