xpoly

draw a polyline or a polygon

Syntax

`xpoly(xv,yv [,dtype [,close]])`

Arguments

xv,yv

matrices of the same size (points of the polyline).

dtype

string (drawing style). default value is "lines".

close

integer. If close=1, the polyline is closed; default value is 0.

Description

`xpoly` draws a single polyline described by the vectors of coordinates `xv` and `yv`. If `xv` and `yv` are matrices they are considered as vectors by concatenating their columns. `dtype` can be `"lines"` for using the current line style or `"marks"` for using the current mark to draw the polyline.

Examples

```x=sin(2*%pi*(0:4)/5);
y=cos(2*%pi*(0:4)/5);

plot2d(0,0,-1,"010"," ",[-2,-2,2,2])
xpoly(x,y,"lines") // by default closed
e=gce(); // get the current entity (the last created: here the polyline)
set(e,"foreground",5);

e.closed = 'off' // the polyline is now open```
```// With marks instead of lines
plot2d(0,0,1,rect=[0,0,12,10], frameflag=3)
t=[0:4]*2*%pi/5;
x=5+5*cos(t);
y=5+5*sin(t);
xpoly(x,y,"marks")
e=gce();
set(e,"mark_style",2);```
