Gen*_*100 1 r ggplot2 pie-chart
我以前使用带有如下表格的 facet wrap 制作了多个折线图,但由于某种原因,我对饼图做同样的事情不太走运;
test <- data.frame(CONFIDENCE = c(rep("Mconfid", 3), rep("Hconfid", 3), rep("SHconfid", 3)),
POPULATION = c(rep(c("African","East_Asian","European"),3)),
AMOUNT = c(0.06, 0.23, 0.71, 0.00, 0.40, 0.60, 0.00, 0.10, 0.90))
test
CONFIDENCE POPULATION AMOUNT
1 Mconfid African 0.06
2 Mconfid East_Asian 0.23
3 Mconfid European 0.71
4 Hconfid African 0.00
5 Hconfid East_Asian 0.40
6 Hconfid European 0.60
7 SHconfid African 0.00
8 SHconfid East_Asian 0.10
9 SHconfid European 0.90

我想要 3 个饼图来使用 ggplot2 在“CONFIDENCE”上进行分面包装或网格
谢谢
如果有人想做多个折线图,这对我有用:
ggplot(test, aes(x=POPULATION, y=AMOUNT, group=CONFIDENCE, color=CONFIDENCE)) + geom_line() + facet_wrap(~ CONFIDENCE)

对于饼图,ggplot您需要设置x为""然后添加coord_polar(主题只是删除值)。
ggplot(data, aes(x="", y=AMOUNT, group=POPULATION, color=POPULATION, fill=POPULATION)) +
geom_bar(width = 1, stat = "identity") +
coord_polar("y", start=0) + facet_wrap(~ CONFIDENCE) +
theme(axis.text = element_blank(),
axis.ticks = element_blank(),
panel.grid = element_blank())
