R ggplot：facet中的不同geom_ablines

本文介绍了R ggplot：facet中的不同geom_ablines的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我想绘制两个不同的 Y截距不受影响。 而不是 yintercept 。此外，您需要映射 aes 中的两个值，否则设置 slope 将覆盖您使用 AES 。这样做： $ b library（ggplot2） dummy1< - expand.grid（X = factor（c（A，B）），Y = rnorm（10）） dummy1 $ D dummy2 ggplot（dummy1，aes（x = D， y = Y））+ geom_point（）+ facet_grid（〜X）+ geom_abline（data = dummy2，aes（截距= Z，斜率= 1）） I want to draw two different geom_ablines in my two facets. Which seem to be working differently to the geom_hline - which is answered here.While library(ggplot2)dummy1 <- expand.grid(X = factor(c("A", "B")), Y = rnorm(10))dummy1$D <- rnorm(nrow(dummy1))dummy2 <- data.frame(X = c("A", "B"), Z = c(1, 0))ggplot(dummy1, aes(x = D, y = Y)) + geom_point() + facet_grid(~X) + geom_hline(data = dummy2, aes(yintercept = Z)).. works, this:library(ggplot2)dummy1 <- expand.grid(X = factor(c("A", "B")), Y = rnorm(10))dummy1$D <- rnorm(nrow(dummy1))dummy2 <- data.frame(X = c("A", "B"), Z = c(1, 0))ggplot(dummy1, aes(x = D, y = Y)) + geom_point() + facet_grid(~X) + geom_abline(data = dummy2, aes(yintercept = Z), slope = 1)does not:Y-intercept is not affected. 解决方案 For geom_abline you need intercept and not yintercept. Furthermore, you need to map both values inside aes, otherwise setting slope overrides what you set with aes. This works:library(ggplot2)dummy1 <- expand.grid(X = factor(c("A", "B")), Y = rnorm(10))dummy1$D <- rnorm(nrow(dummy1))dummy2 <- data.frame(X = c("A", "B"), Z = c(1, 0))ggplot(dummy1, aes(x = D, y = Y)) + geom_point() + facet_grid(~X) + geom_abline(data = dummy2, aes(intercept = Z, slope = 1)) 这篇关于R ggplot：facet中的不同geom_ablines的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
