xpolys

xpolys — draw a set of polylines or polygons

Calling sequence

xpolys(xpols,ypols,[draw])

`xpols,ypols`	: matrices of the same size (p,n) (points of the polylines).
`draw`	: vector of size n.

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.
