Add pie chart color palettes
With the help of.pal function of the RColorBrewer package in R.
R
Get the library.library(RColorBrewer)# Create data for the graph.geeks <- c(23, 56, 20, 63)labelss <- c("Mumbai", "Pune", "Chennai", "Bangalore")labels<- brewer.pal(length(geeks), "Set2") pie(geeks, labels = labelss) |
Output:
R – Pie Charts
modify the line type of the borders of the plot we can make use of the lty argument:
R
Get the library.library(RColorBrewer)# Create data for the graph.geeks <- c(23, 56, 20, 63)labelss <- c("Mumbai", "Pune", "Chennai", "Bangalore")labels<- brewer.pal(length(geeks), "Set2") pie(geeks, labels = labelss, col = color, lty = 2) |
Output:
R – Pie Charts
Add shading lines with the density argument.

Output:

R – Pie Charts
A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportions. It depicts a special chart that uses “pie slices”, where each sector shows the relative sizes of data. A circular chart cuts in the form of radii into segments describing relative frequencies or magnitude also known as a circle graph.
