| Applies To: | Circle | Ellipse |
Description
This property specifies one or more start-angles for an arc, pie-slice, or chord of a circle or ellipse. It may be used in conjunction with End which specifies end angles. Angles are measured counter-clockwise from the x-axis at the centre of the object.
If a single arc is being drawn, Start is a single number that specifies the start angle of the arc in radians (0 ⍎> ○2). If multiple arcs are being drawn, Start is either a single number as before (the start angle for several concentric arcs) or a numeric vector with one element per arc.
If End is not specified, the default value of Start is 0. Otherwise, the default value of Start is (0,¯1↓+\End).
