Pie (procedure)

Creates a pie slice shape, which can then be rendered using stroke, fill, or strokeandfill.

Syntax

pie( x, y, radius, startangle, endangle )

Arguments

x, y

Measure values representing the horizontal/vertical position, in inches, of a circle's center representing the whole pie from

which to draw a slice.

radius

Measure value representing the length, in inches, of the segments of the pie, i.e. its radius.

startangle, endangle

Measure values representing the angles, in degrees, of both segments of the pie slice. Values increase counter clock wise,

with 0 extending right from the center of the circle.

Code Sample Example

This example draws a whole pie chart with a shadow effect.

Example

setfillcolor([0,0,0,50]) %Set shadow colour to gray

pie(1.5,1.5,1,60,290) %Create shadow for first slice

translate(0.2,0.2) %Separate shadows

pie(1.5,1.5,1,290,420) %Create shadow for second slice

fill() %Display shadows

translate(-0.3, 0.3) %Offset chart from its shadow

setstrokecolor([0,0,100,0]) %Set pen colour to yellow

setfillcolor([0,100,100,0]) %Set fill colour to red

pie(1.5,1.5,1,60,290) %Create first slice

strokeandfill() %Draw first slice
