.TH xpoly 2 "April 1993" "Scilab Group" "Scilab Function"
.so ../sci.an
.SH NAME
xpoly - draw a polyline or a polygon
.SH CALLING SEQUENCE
.nf
xpoly(xv,yv [,dtype [,close]])
.fi
.SH PARAMETERS
.TP 7
xv,yv
: matrices of the same size (points of the polyline).
.TP
dtype
: string (drawing style). default value is "lines".
.TP
close
: integer. If close=1, the polyline is closed; default value is 0.
.SH DESCRIPTION
\fVxpoly\fR draws a single polyline described by the vectors of coordinates
\fVxv\fR
and \fRyv\fR. If \fVxv\fR and \fVyv\fR are matrices
they are considered as vectors by concatenating their columns.
\fVdtype\fR can be \fV"lines"\fR for using the current line style or
\fV"marks"\fR for using
the current mark to draw the polyline.
.SH EXAMPLE
.nf
x=sin(2*%pi*(0:5)/5);
y=cos(2*%pi*(0:5)/5);
plot2d(0,0,-1,"010"," ",[-2,-2,2,2])
xset("dashes",5)
xpoly(x,y,"lines",1)
xset("default")
