本文介绍了在ggplot2中左键调整标题或ggtitle的绝对位置的处理方法,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 ggplot(data = economics,aes(x =日期,y =失业))+ geom_line()+ ggtitle(1967年至2007年间美国的失业率)+ xlab()+ ylab(失业[千]) 第一次尝试 ggplot(data = economics,aes(x = date,y = unemploy))+ geom_line()+ ggtitle(美国失业多年)+ xlab()+ ylab(失业[千])+ 主题(plot.title = element_text(hjust = -0.45,vjust = 2.12))) Yay成功!但是等等......还有更多......现在我想把标题改为别的。 ggplot(data = economics ,aes(x =日期,y =失业))+ geom_line()+ ggtitle(1967年至2007年间美国的失业率)+ xlab()+ ylab(失业[千])+ 主题(plot.title = element_text(hjust = -0.45,vjust = 2.12)) 现在我需要调整hjust ...:(b / b) 问题 我怎样才能让标题左对齐(y轴标签左边的几个像素)并且不会影响正确的值?或者hjust和长度之间的关系是什么的字符串? 我试图手动注释根据这个问题,但然后我 谢谢! 只有标题,没有别的出于某种原因 - 解决方案直到有人提出更好的解决方案,其中一种方式就像 library( ggplot2) library(grid) library(gridExtra)p geom_line() + labs(x = NULL,y =失业[千],title = NULL) title.grob< - textGrob( label =美国的失业几年,x = unit(0,lines),y = unit(0,lines), hjust = 0,vjust = 0, gp = gpar(fontsize = 16)) p1 grid.draw(p1) I would like to left align the title in a plot like thisggplot(data = economics, aes(x = date, y = unemploy)) + geom_line() + ggtitle("Unemployment in USA between 1967 and 2007") + xlab("") + ylab("Unemployed [thousands]")First attemptggplot(data = economics, aes(x = date, y = unemploy)) + geom_line() + ggtitle("Unemployment in USA for some years") + xlab("") + ylab("Unemployed [thousands]") + theme(plot.title = element_text(hjust = -0.45, vjust=2.12)))Yay success! But wait... there's more... now I want to change the title to something else.ggplot(data = economics, aes(x = date, y = unemploy)) + geom_line() + ggtitle("Unemployment in USA between 1967 and 2007") + xlab("") + ylab("Unemployed [thousands]") + theme(plot.title = element_text(hjust = -0.45, vjust=2.12))So now I need to adjust hjust... :(The questionHow can I make the title left justified (a couple of pixels left of the y axis label or so) over and over again without messing with the hjust value? Or what is the relationship between hjust and the length of the string?I have tried to annotate manually according to this question, but then I got only the title, and nothing else for some reason - and an error.Thank you! 解决方案 Until someone comes up with a better solution, one way would be something like library(ggplot2)library(grid)library(gridExtra)p <- ggplot(data = economics, aes(x = date, y = unemploy)) + geom_line() + labs(x = NULL, y = "Unemployed [thousands]", title = NULL)title.grob <- textGrob( label = "Unemployment in USA for some years", x = unit(0, "lines"), y = unit(0, "lines"), hjust = 0, vjust = 0, gp = gpar(fontsize = 16))p1 <- arrangeGrob(p, top = title.grob)grid.draw(p1) 这篇关于在ggplot2中左键调整标题或ggtitle的绝对位置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! 09-25 21:03
