myfactor<-reorder(x,X,FUN=。。)其中,x参数是一个离散型的向量,X是与x等长的一个变量,按照fun(X)对x进行排序即可 8、stat参数 加上stat=“identity”的参数,类似于weight的功能 ggplot(data=mtcars,mapping=aes(x=factor(cyl),y=wt))+geom_bar(color="red",fill="blue",alpha=0.5,stat="identity")...

Basic bar chart # Notics that in this chart we only gave x = manufacturer. The y axis has not been defined.pl <- ggplot(data = mpg,aes(x= manufacturer)) pl <- pl + geom_bar() pl # The reason is that by default the geom_bar used the frequence count of the x axis value. eg...
Let’s assume that we want to create a ggplot2 barchart with a line on top, where the bars represent the sample column and the line represents the responses column. In order to use the functions of theggplot2 package, we also need to install and load ggplot2. ...
Bar chart withgeom_col geom_col geom_colis the same asgeom_bar(stat = "identity"), so if your data contains groups and the count for each group you can just use this function instead. # install.packages("ggplot2")library(ggplot2)ggplot(df,aes(x=group,y=count))+geom_col() ...
但是,如果您要制作Y给出的绝对数的条形图,则需要stat="identity"在内进行设置geom_ba。 # 显示数据 head(mtcars) plot1 <- ggplot(mtcars, aes(x=cyl)) + # 画柱状图 geom_bar() + # Y axis derived from counts of X item labs(title="Frequency bar chart") print(plot1) A data.frame: 6 ...
Barplot with multiple groups Create stacked and dodged bar plots. Use the functionsscale_color_manual()andscale_fill_manual()to set manually the bars border line colors and area fill colors. # Stacked bar plots of y = counts by x = cut,# colored by the variable colorggplot(df2, aes(x ...
