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)
