Display labels on a 3D pie chart
Displays labels on a 3D pie chart.
pie3D.labels(radialpos,radius=1,height=0.1,theta=pi/6,
labels,labelcol=par("fg"),labelcex=1.5,labelrad=1.25,minsep=0.3)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 |
labelrad |
The expansion for the labels around the pie. |
minsep |
The minimum angular separation between label positions. |
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.
