[英]How to change the order of x-axis in multiple boxplots in R
I am trying to change the order x-axis in this boxplot. 我正在尝试更改此箱图中的x轴顺序。
[Now the order is loupe, microscope and video, and I want to change it to microscope, loupe then video] [现在的订单是放大镜,显微镜和视频,我想将其更改为显微镜,放大镜和视频]
The dataframe example is like this 数据框示例如下所示
Label Mental Physical Temporal Performance Effort Frustration sum
Microscope 10 10 10 10 10 10 60
Microscope 10 10 10 10 10 10 60
Loupe 20 20 20 20 20 20 120
Loupe 20 20 20 20 20 20 120
Video 15 15 15 20 20 20 105
Video 15 15 15 20 20 20 105
This is boxplot i have right now boxplot1 这是我现在拥有的boxplot boxplot1
This is my code for ggplot 这是我的ggplot代码
mydata <- read.csv("boxplotyiyu2.csv",header=TRUE)
dfm <- melt(mydata, id.var = "Label")
ggplot(data = dfm, aes(x=variable, y=value)) + geom_boxplot(aes(fill=Label),width=0.5)+ xlab("Demand") + ylab("NASA-TLX Scores")
And I have tried this, but the result is not correct. 我已经尝试过了,但是结果不正确。
dfm$variable <- factor(dfm$variable,levels = c("Microscope","Loupe","Video"))
Another question is how to modify the y-axis for multiple boxplots. 另一个问题是如何修改多个箱形图的y轴。 I have this seven boxplots together, but i want to change the y-axis for each small plot. 我将这七个箱形图放在一起,但是我想为每个小图更改y轴。 boxplot2 boxplot2
(The dataframe is similar with above one, just replace mental,physical...with angle data) (数据框与上面的数据框相似,只是将角度,物理...替换为角度数据)
The code I have is 我的代码是
df.m <- melt(mydata, id.var = "Label")
p <- ggplot(data = df.m, aes(x=variable, y=value))
p <- p + geom_boxplot(aes(fill=Label))
p <- p + facet_wrap( ~ variable, scales="free")
p <- p + xlab("Angle") + ylab("Degree")
Please do me a favor! 请帮我一个忙! Really appreciate it! 真的很感激!
You will need to redefine the order of the factors with the factor
function. 您将需要使用factor
函数重新定义因素的顺序。
#Sample data
Label<-c("Microscope", "Microscope", "Loupe", "Loupe", "Video", "Video")
mydata<-data.frame(Label)
#print out
levels(mydata$Label)
mydata$Label<-factor(mydata$Label, levels=c("Microscope", "Loupe", "Video"))
#print out
levels(mydata$Label)
