如何在R中的多个箱形图中更改x轴的顺序 [英] How to change the order of x-axis in multiple boxplots in R
问题描述
我试图改变这个boxplot的订单x轴。
[现在订单是放大镜,显微镜和视频,我想将其更改为显微镜,放大镜,然后视频]
数据框示例就像这样

这是我现在拥有的boxplot
boxplot1
这是我的代码ggplot
mydata < - read.csv(boxplotyi (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分数)
我试过这个,但结果不正确。
dfm $ variable < - factor(dfm $ variable,levels = c(Microscope,Loupe,Video))
另一个问题是如何修改多个箱形图的y轴。
我有这七个箱形图,但我想改变每个小图的y轴。
boxplot2
< (数据框与上面的数据框相似,只是用角度数据代替智力,物理......)
我有的代码是
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)
帮我个忙!真的很感谢!
您需要重新定义因子< code $>
#示例数据
标签< -c(Microscope,Microscope ,放大镜,放大镜,视频,视频)
mydata <-data.frame(标签)
#打印出
等级(mydata $标签)
mydata $标签< -factor(mydata $ Label,levels = c(Microscope,Loupe,Video))
#打印
等级( mydata $ Label)

I am trying to change the order x-axis in this boxplot.
[Now the order is loupe, microscope and video, and I want to change it to microscope, loupe then video]
The dataframe example is like this
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
This is my code for ggplot
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.
dfm$variable <- factor(dfm$variable,levels = c("Microscope","Loupe","Video"))
Another question is how to modify the y-axis for multiple boxplots. I have this seven boxplots together, but i want to change the y-axis for each small plot. boxplot2
(The dataframe is similar with above one, just replace mental,physical...with angle data)
The code I have is
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! Really appreciate it!
You will need to redefine the order of the factors with the factor
function.
#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)
