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=NA,radius=1,height=0.1,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.
If ‘explode’ is zero, only the top and outer side of each sector will be displayed. This will sometimes fix the problem of a pie with one huge sector greater than 3*pi/2 that cannot otherwise be drawn.
Value
The bisector of the pie sector in radians.
