Hi All,
I have a question to ggplot 2. My code is the following:
-- cut --
library(ggplot2)
library(scales)
df <-
data.frame(group = c("Male", "Female", "Child"),
value = c(25, 25, 50))
blank_theme <- theme_minimal() + theme(
axis.title.x = element_blank(),
axis.title.y = element_blank(),
axis.text.x = element_blank(),
panel.border = element_blank(),
panel.grid = element_blank(),
axis.ticks = element_blank(),
plot.title = element_text(size = 4, face = "bold"))
ggplot(df, aes(x = "", y = value, fill = group)) +
geom_bar(
width = 1,
stat = "identity") +
coord_polar("y", start = 0) +
scale_fill_brewer(
name = "Gruppe",
palette = "Blues") +
blank_theme +
geom_text(
aes(
y = c(10, 40, 75),
label = scales::percent(value/100)),
size = 5) +
labs(title = "Pie Title")
-- cut --
Is there a way to give the position of the labels to the chunks of the pie
in a generalized form instead of finding the value interatively by
trial-n-error?
How can I adjust the title of the graph converning font height and postion
(e. g. center)?
Kind regards
Georg
