pie3D.labels {plotrix}R Documentation

Display labels on a 3D pie chart

Description

Displays labels on a 3D pie chart.

Usage

 pie3D.labels(radialpos,radius=1,height=0.3,theta=pi/6,
  labels,labelcol=par("fg"),labelcex=1.5,minsep=0.3)

Arguments

radialpos Position of the label in radians
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
labels The label to display
labelcol The color of the labels
labelcex The character expansion factor for the labels
minsep The minimum angular separation between label positions.

Details

pie3D.label displays labels on a 3D pie chart. The positions of the labels are given as angles in radians (usually the bisector of the pie sectors). As the labels can be passed directly to pie3D, this function would probably not be called by the user.

pie3D.labels tries to separate labels that are placed closer than minsep radians. This simple system will handle minor crowding of labels. If labels are very crowded, capturing the return value of pie3D and editing the label positions may allow the user to avoid manually placing labels.

Value

nil

 pie3D.labels(bisectors,labels=pielabels)
