使用 ggtern 的三角图
triangular plot using ggtern
我正在尝试用三角图中的某些区域对某些点进行三重绘制此代码:
library(ggtern)
g <- data.frame(x=c(1,.6,.6), y=c(0,.4,0), z=c(0,0,.4), Series="Green")
r <- data.frame(x=c(0,0.4,0), y=c(0,0,0.4), z=c(1,0.6,0.6), Series="Red")
p <- data.frame(x=c(0,0.4,0), y=c(1,0.6,0.6), z=c(0,0,0.4), Series="Purple")
DATA = rbind(g,r,p)
plot <- ggtern(data=DATA,aes(x,y,z)) +
geom_polygon(aes(fill=Series),alpha=.5,color="black",size=0.25) +
scale_fill_manual(values=as.character(unique(DATA$Series))) +
theme(legend.position=c(0,1),legend.justification=c(0,1)) +
labs(fill="Region",title="Sample Filled Regions")
print(plot)
我想在该图中添加一些取自文本文件的点,我正在读取它们的 x、y 和 z 坐标。我如何才能将这些点指向情节?
如果我尝试这样的操作,它会删除之前的情节:
plot <- ggtern(data = data.frame(x = cordnate_x, y = cordnate_y, z = cordnate_z),aes(x, y, z)) + geom_point() +theme_rgbg()
print(plot)
这是需要加分的情节
traingular plot
您可以像拥有普通的 ggplot 对象一样添加点。
