[英]How to make funnel chart with bars in R ggplot2?
I want to make a funnel chart in R with ggplot2 as following: https://chartio.com/assets/c15a30/tutorials/charts/funnel-charts/c7cd4465bc714689646515692b6dbe7c74ae7550a265cd2d6a530f1f34d68ae1/funnel-chart-example.png
我的代码看起来像这样,但我不知道如何在条形之间填充浅蓝色。 (也许有多边形?)
library(ggplot2)
library(reshape2) # for melt()
library(dplyr)
# get data
dat <- read.table(text=
"steps numbers rate
clicks 332835 100.000000
signup 157697 47.379933
cart 29866 8.973215
buys 17012 5.111241",
header = T)
barWidth <- 0.9
# add spacing, melt, sort
total <- subset(dat, rate==100)$numbers
dat$padding <- (total - dat$numbers) / 2
molten <- melt(dat[, -3], id.var='steps')
molten <- molten[order(molten$variable, decreasing = T), ]
molten$steps <- factor(molten$steps, levels = rev(dat$steps))
ggplot(molten, aes(x=steps)) +
geom_bar(aes(y = value, fill = variable),
stat='identity', position='stack') +
geom_text(data=dat,
aes(y=total/2, label= paste(round(rate), '%')),
color='white') +
scale_fill_manual(values = c('grey40', NA) ) +
coord_flip() +
theme(legend.position = 'none') +
labs(x='steps', y='volume')
这应该只是一个评论,因为您明确要求提供ggplot
解决方案,但事实并非如此 - 我纯粹出于代码格式化的原因将其发布为答案。
您可以考虑plotly
,它具有漏斗类型。 就像是
library(plotly)
dat %>% mutate(steps=factor(steps, unique(steps)),
rate=sprintf("%.2f%%", rate)) %>%
plot_ly(
type = "funnel",
y = ~steps,
text= ~rate,
x = ~numbers)
可以让你开始; 我并没有真正掌握数据中的填充,所以这可能不是你想要的。
