TArc::TArc ( )

Referenced by DrawArc().

TArc::TArc ( Double_t  x1,
Double_t  y1,
Double_t  r1,
Double_t  phimin = 0,
Double_t  phimax = 360 
)

Arc normal constructor.

Parameters
[in]x1,y1coordinates of centre of arc
[in]r1arc radius
[in]phiminmin angle in degrees (default is 0–>360)
[in]phimaxmax angle in degrees (default is 0–>360)

When a circle sector only is drawn, the lines connecting the center of the arc to the edges are drawn by default. One can specify the drawing option "only" to not draw these lines.
