本文介绍了在`facet_wrap`ed网格中,在保留`free_x`的同时以0为中心绘制子图的处理方法,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 有什么办法可以将两个子图放在 0 ,同时为 x / max 值c> axis? 在下面的情况下,左边是 xlim = c(-1,1)和 xlim = c(-2,2)表示正确,但它应该是通用的。 (in一个真实的例子,那些是多面的火山地块,我想集中在 0 效果大小,但保持不同 x (b) library(ggplot2) df = data.frame(x = c(1,2 ),y = c(0,0),group = c(1,2)) ggplot(df,aes(x = x,y = y))+ geom_point()+ facet_wrap(〜group,scale =free_x) 解决方案我有一个也需要像这样并排显示不对称光谱, 试试这个函数, symmetrise_scale gb< - ggplot_build(p) type< - 开关(轴,x=x.range,y=y.range) lims< - sapply(gb $ panel $ ranges,[[,type) fname< - as.character(p $ facet $ facets) facets< - gb $ panel $ layout [[fname (b)(b)(b)(b)(b)(b)(b)(b) data.frame(rep(facets,each = 2),lims2),c(fname,axis)) switch(axis,x= p + geom_blank(data = dummy,aes(x = x,y = Inf),inherit.aes = FALSE),y= p + geom_blank(data = dummy,aes(x = Inf,y = y),inherit.aes = FALSE))} 库(ggplot2) = df = data.frame(x = c(1,2),y = c(5,0.2),group = c(1,2))p symmetrise_scale(p,x) symmetrise_scale( p,y) In the plot below, I have a faceted grid.Is there any way to center both subplots at 0, while keeping different min/max values for the x axis?In the case below that would be xlim=c(-1,1) for left and xlim=c(-2,2) for right, but it should be generally applicable.(in a real life example, those are faceted volcano plots and I want to center at 0 effect size but keep the different x scales for different plots)library(ggplot2)df = data.frame(x=c(1,2), y=c(0,0), group=c(1,2))ggplot(df, aes(x=x, y=y)) + geom_point() + facet_wrap(~group, scale="free_x") 解决方案 I've also needed something like this to display asymmetric spectra side-by-side,Try this function,symmetrise_scale <- function(p, axis = "x"){ gb <- ggplot_build(p) type <- switch(axis, "x" = "x.range", "y" = "y.range") lims <- sapply(gb$panel$ranges, "[[", type) fname <- as.character(p$facet$facets) facets <- gb$panel$layout[[fname]] lims2 <- as.vector(t(tcrossprod(apply(abs(lims), 2, max), c(-1,1)))) dummy <- setNames(data.frame(rep(facets, each=2), lims2), c(fname, axis)) switch(axis, "x" = p + geom_blank(data=dummy, aes(x=x, y=Inf), inherit.aes = FALSE), "y" = p + geom_blank(data=dummy, aes(x=Inf, y=y), inherit.aes = FALSE))}library(ggplot2)df = data.frame(x=c(1,2), y=c(5,0.2), group=c(1,2))p <- ggplot(df, aes(x=x, y=y)) + geom_point() + facet_wrap(~group, scale="free")symmetrise_scale(p, "x")symmetrise_scale(p, "y") 这篇关于在`facet_wrap`ed网格中,在保留`free_x`的同时以0为中心绘制子图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!
