本文介绍了指定ggplot2面板宽度的处理方法,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 29岁程序员,3月因学历无情被辞! 我在同一页面上有两个ggplots,我希望它们的面板宽度相同。 一些示例数据: dfr1 time = 1:10, value = runif(10) ) dfr2< - data.frame( time = 1:10, value = runif(10,1000,1001)) 一张在另一张下面的图: p1 p2 grid.newpage() pushViewport(viewport(layout = grid.layout(2,1))) print(p1,vp = viewport(layout.pos.row = 1, layout.pos.col = 1)) print(p2,vp = viewport(layout.pos.row = 2,layout.pos.col = 1)) 如何在每个图表中指定面板宽度和位置,以便让它们排列? (我不想将这些情节与分面相结合;这在我的现实世界中是不合适的) 解决方案原始解决方案: #install.packages(ggExtra,repos =http://R-Forge.R-project.org)#library(ggExtra)#align.plots( p1,p2) 编辑(22/03/13): 由于ggExtra不再存在(并且ggplot2的许多内部已经改变),最好使用gtable包提供的合并函数(rbind,cbind)。 gl = lapply(list(p1,p2),ggplotGrob) library(gtable)g = do.call(rbind,c gl,size =first))g $ widths = do.call(unit.pmax,lapply(gl,[[,widths)) grid.newpage ) grid.draw(g) I have two ggplots on the same page, and I'd like their panels to be the same width.Some sample data:dfr1 <- data.frame( time = 1:10, value = runif(10))dfr2 <- data.frame( time = 1:10, value = runif(10, 1000, 1001))One plot below the other:p1 <- ggplot(dfr1, aes(time, value)) + geom_line()p2 <- ggplot(dfr2, aes(time, value)) + geom_line()grid.newpage()pushViewport(viewport(layout = grid.layout(2, 1)))print(p1, vp = viewport(layout.pos.row = 1, layout.pos.col = 1))print(p2, vp = viewport(layout.pos.row = 2, layout.pos.col = 1))How do I specify the panel widths and positions in each plot, in order to make them line up?(I don't want to combine the plots with faceting; it isn't appropriate in my real-world example.) 解决方案 Original solution: # install.packages("ggExtra", repos="http://R-Forge.R-project.org") # library(ggExtra) # align.plots(p1, p2)Edit (22/03/13):Since ggExtra doesn't exist anymore (and many internals of ggplot2 have changed), it's better to use the merging functions (rbind, cbind) provided by the gtable package,gl = lapply(list(p1,p2), ggplotGrob)library(gtable)g = do.call(rbind, c(gl, size="first"))g$widths = do.call(unit.pmax, lapply(gl, "[[", "widths"))grid.newpage()grid.draw(g) 这篇关于指定ggplot2面板宽度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! 上岸,阿里云!
