[英]Clustered Bar Plot Using ggplot2
Basically I want to display a barplot which is grouped by Methods ie I want to display the number of people conducted the tests, the number of positive test results had found for each of the methods.基本上我想显示一个按方法分组的条形图,即我想显示进行测试的人数,每种方法发现的阳性测试结果的数量。 Also, I want to display all the numbers and percentages as labels on the bar.
另外,我想在栏上显示所有数字和百分比作为标签。 I am trying to display these using ggplot2.
我正在尝试使用 ggplot2 显示这些。 But I am failing every time.
但我每次都失败了。
Any helps.任何帮助。
Thanks in advance提前致谢
I'm not sure to have fully understand your question.我不确定是否完全理解你的问题。 But I will suggest you to take look on
geom_text
.但我会建议你看看
geom_text
。
library(ggplot2)
ggplot(df, aes(x = methods, y = percentage)) +
geom_bar(stat = "identity") +
geom_text(aes(label = paste0(round(percentage,2), " (",positive," / ", people,")")), vjust = -0.3, size = 3.5)+
scale_x_discrete(limits = c("NS1", "NS1+IgM", "NS1+IgG","Tourniquet")) +
ylim(0,100)
Data:数据:
df = data.frame(methods = c("NS1", "NS1+IgM","NS1+IgG","Tourniquet"),
people = c(542,542,541,250),
positive = c(505,503,38,93))
df$percentage = df$positive / df$people * 100
> df
methods people positive percentage
1 NS1 542 505 93.17343
2 NS1+IgM 542 503 92.80443
3 NS1+IgG 541 38 7.02403
4 Tourniquet 250 93 37.20000
