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.
