Hello,
I'm trying to make a 3D pie chart, but my labels are overlapping. I see
that labelpos could offer a solution to this, but I have been unable to
find any code snippets that indicate what type of value this argument
requires. Any guidance would be appreciated!
Hi Tiffany,
Labels are placed at the "middle" of each sector of the pie by default.
The easiest way to change the position of one label is to capture the
return value of pie3D, which is the position of the labels in radians
(using the example):
bc<-pie3D(pieval,radius=0.9,labels=pielabels,explode=0.1,
main="3D PIE OPINIONS")
You can then see where the labels have been placed:
bc
[1] 0.3141593 1.2566371 2.8274334 5.0265482
You can change the positions like this:
bc[4]<-4.5
pie3D(pieval,radius=0.9,labels=pielabels,explode=0.1,
main="3D PIE OPINIONS",labelpos=bc)
