Pie-Charts mit R und ggplot2
Here’s a simple example how to create a pie-chart (in PDF format) with R’s ggplot2 library.
pdf(file = "g:/test.pdf")
library("ggplot2")
df <- data.frame(
Legende = c("male", "female", "child"),
werte = c(20, 20,60)
)
blue <- rgb(26/255, 115/255, 186/255, 1)
yellow <- rgb(255/255, 219/255, 67/255, 1)
orange <- rgb(181/255, 75/255, 5/255, 1)
ggplot(df, aes(x = "", y = werte, fill = Legende)) +
geom_bar(width = 1, stat = "identity") +
scale_fill_manual(values = c(blue, yellow, orange)) +
coord_polar("y", start = 0) +
labs(title = "Ein einfacher Pie-Chart") +
xlab("X-Achse") +
ylab("Y-Achse")
dev.off()
