xarcs

draw parts of a set of ellipses

Calling Sequence

xarcs(arcs,[style])

Arguments

:arcs matrix of size (6,n) describing the ellipses. : :style row vector of size n giving the style to use. :

Description

xarcs draws parts of a set of ellipses described by arcs: arcs=[x y w h a1 a2;x y w h a1 a2;...]’ where each ellipse is defined by the 6 parameters (x,y,w,h,a1,a2) (see xarc).

x, y, w, h parameters are specified in user coordinates.

style(i) gives the color used to draw ellipse number i.

Sample

Examples

`plot2d`_(0,0,-1,"031"," ",[-1,-1,1,1])
arcs=[-1.0 0.0 0.5; // upper left x
       1.0 0.0 0.5; // upper left y
       0.5 1.0 0.5; // width
       0.5 0.5 1.0; // height
       0.0 0.0 0.0; // angle 1
       180*64 360*64 90*64]; // angle 2
xarcs(arcs,[1,2,3])
