Guide Section: Diagramming | EASAP Tree: DIAGRAM LIST

SECTOR draws a sector of a circle ('pie slice') or an annular ring.

SECTOR is defined by the parameters below:

• An origin point about which the sector is rotated,
• The inner and outer radii of the sector,
• The starting and ending angles of the sector.

To specify a SECTOR of a circle, set the inner radius to zero.

To specify an arc of a circle by setting the inner and outer radii to the same value.

An angle value of zero is from the origin out along the positive x-axis (horizontal); angle values increase in a counter-clockwise direction.

Tip: You can use inline units of deg after the angle values in the Angles: parameter to avoid entering values in the default units of radians.

SECTOR
Essential Parameters:
Origin:	Point coordinates at the center of sector rotation: x0,y0
Radii:	Inner and outer radii of sector: Ri, Ro
Angles:	Starting and ending angles in radians: a1,a2. The zero angle is aligned horizontally from the origin out along the positive X-axis; angle values then increase in a counter-clockwise direction.
Optional Parameters:
Show if:	Logical expression, if FALSE then shape NOT shown else default→TRUE
Fill Style:	Select fill style from list. (default→Black, Opaque)
Line Style:	Select line style from list. default→Transparent
Transform:	Select one or more transforms from list. Order selected is order applied.
