For example, here’s what the “blues” color scale looks like: ggplot(data, aes(x="", y=amount, fill=category)) + ![]() You can also customize the colors of the slices by simply choosing one of the brewer color scales. Tip: Use this Hex Color Picker to find combinations of hex color codes that go well together. We can customize the chart even further by specifying our own hex colors to use for the slices with the scale_fill_manual() argument: ggplot(data, aes(x="", y=amount, fill=category)) + Geom_text( aes(label = paste0(amount, " %")), position = position_stack(vjust= 0.5)) + We can further improve the appearance of the chart by adding labels inside the slices: ggplot(data, aes(x="", y=amount, fill=category)) + The simplest way to improve the appearance is to use theme_void(), which removes the background, the grid, and the labels: ggplot(data, aes(x="", y=amount, fill=category)) + The default pie chart in ggplot2 is quite ugly. How to Modify the Appearance of the Pie Chart Ggplot(data, aes(x="", y=amount, fill=category)) + The following code shows how to create a basic pie chart for a dataset using ggplot2: library(ggplot2)ĭata <- ame(" category" = c('A', 'B', 'C', 'D'), This tutorial explains how to create and modify pie charts in R using the ggplot2 data visualization library. ![]() A pie chart is a type of chart that is shaped like a circle and uses slices to represent proportions of a whole.
