我有2个时间序列数据，我想在一个具有不同颜色的ggplot中绘制ACF，我刚刚找到了ggAcf，但无法解决我的问题

I have 2 time series data and I want to plot the ACF in one ggplot with different colour, I just found ggAcf, but it couldn't solve my problem

library(ggplot2) data1<-seq(1,300,3) data2<-seq(1,100,0.5) ggAcf(data2,1) ggAcf(data2,20)

我想按照以下类型绘制剧情

I want to make the plot as follow type

我该如何解决?

推荐答案

library(ggplot2) library(reshape2) data1 <- seq(1, 300, 3) data2 <- seq(1, 100, 0.5) acf1 <- acf(data1, plot = F, lag.max = 25) acf2 <- acf(data2, plot = F, lag.max = 25) df<- data.frame(lag = acf1$lag,acf1=acf1$acf,acf2=acf2$acf) colnames(df)<-c("lag","data1","data2") data<-melt(df,id="lag") ggplot(data, aes(x=lag, y=value)) + geom_area(aes(colour = variable, fill= variable), position = 'stack')
