draw.tilted.sector {plotrix}R Documentation

Display a 3D pie sector

Description

Displays a 3D pie sector.

Usage

 draw.tilted.sector(x=0,y=0,edges=100,radius=1,height=0.3,theta=pi/6,
  start=0,end=pi*2,border=par("fg"),col=par("bg"),explode=0,shade=0.8)

Arguments

x,y Position of the center of the pie sector in user units
edges Number of edges to draw a complete ellipse
radius the radius of the pie in user units
height the height of the pie in user units
theta The angle of viewing in radians
start Starting angle of the sector
end Ending angle of the sector
border The color of the sector border lines
col Color of the sector
explode How far to "explode" the sectors in user units
shade If > 0 and < 1, the proportion to reduce the brightness of the sector color to get a better 3D effect.

Details

draw.tilted.sector displays a single 3D pie sector. It is probably only useful when called from pie3D. The shade argument proportionately reduces the brightness of the RGB color of the sector to produce a top lighted effect.

Value

The bisector of the pie sector in radians.
