Fill parts of a set of ellipses
xfarcs(arcs,[style])
:arcs matrix of size (6,n) describing the ellipses. : :style row vector of size n giving the colors to use. :
xarcs fills 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 xfarc).
x, y, w, h parameters are specified in user coordinates.
style(i) gives the color number for filling ellipse number i.
If a2 is equal to 360*64, a complete circle will be drawn.
