# xpolys

draw a set of polylines or polygons

### Calling Sequence

`xpolys(xpols,ypols,[draw])`

### Arguments

xpols,ypols

matrices of the same size (p,n) (points of the polylines).

draw

vector of size n.

### Description

`xpolys` draws a set of polylinse using marks or dashed lines. The coordinates of each polyline are stored in a column of `xpols` and `ypols`.

The style of polyline i is given by `draw(i)`:

• If `draw(i)` is negative, the mark with id `-draw(i)` is used to draw polyline i (marks are drawn using the current pattern). Use `xset()` to see the meaning of the ids.

• If `draw(i)` is strictly positive, the line style (or color) with id `draw(i)` is used to draw polyline i. Use `xset()` to see the meaning of the ids.

### Examples

```plot2d(0,0,-1,"012"," ",[0,0,1,1])
rand("uniform")
xset("color",3)
xpolys(rand(3,5),rand(3,5),[-1,-2,0,1,2])```
