Drawing Wedges

	A wedge is a section of a circle. Wedges are commonly used to draw
	pie charts. You can draw a wedge by outlining (edging) the defined
	area using the Edge Wedge (EW) command, or you can create filled
	wedges using the Fill Wedge (WG) command.
	The wedge commands use your current pen location as the center
	point; you specify the radius, the start angle, and the sweep angle.
	The radius determines the length of the two sides of the wedge.
	The sign (positive or negative) of the radius determines the location
	of a ‘zero-degree’ reference point. Thestart angle is the number of
	degrees from the zero reference point at which you want to draw the
	first radius. The sweep angle is the number of degrees through which
	you want to draw the arc. To draw or fill a circle, simply specify a
	360-degree sweep angle. Figure 21-4 shows the different parameters
	of a wedge with a positive radius.
Note	A positive angle of rotation is in the direction of the +X-axis to the
	+Y-axis as shown below. A negative angle of rotation is in the
	direction of the +X-axis to the –Y-axis.

Note

Figure 21-3

The relationship of the +X-axis to +Y-axis (and –Y-axis) can change as a result of the scaling point or scaling factor changes, thus, changing the direction of a positive (or negative) angle of rotation.
