本文介绍了ggplot传说中的斜线的处理方法,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! 这肯定会让过去的人恼火,所以如果这是重复的,我会删除它。使用 geom_bar 时可能会令人讨厌。例如: x y df a a + geom_bar(color =black)+ scale_fill_manual(values = c(white,black)) 当我使用彩色条纹时,我使用这个工作,首先绘制没有颜色的条,例如 a + geom_bar()+ geom_bar(color =black,show_guide = FALSE)+ scale_fill_manual(values = c(white,black)) 然而,当填充为白色时,这会在图例中留下不带边框的令人满意的空白框。例如 过去我使用图形软件手动修复了这个问题,但是现在我认为这对于有足够的人在这里提出问题必须有用。我们可以让 ggplot 只绘制黑色轮廓但没有斜线的图例吗?解决方案 a + geom_bar()+ geom_bar(color =black,show_guide = FALSE)+ scale_fill_manual(values = c(white,black))+ opts(legend.key = theme_rect(fill ='black')) 给了我这个, 感谢本网站。 Alos,使用 color 而不是填充 a + geom_bar()+ geom_bar(color =black)(可能有人认为其中一种比较好) ,show_guide = FALSE)+ scale_fill_manual(values = c(white,black))+ opts(legend.key = theme_rect(color ='black')) 重要说明:现代版本的ggplot2 opts 已被弃用,并被替换为 theme ,并且 theme_rect 已被替换为 element_rect 。 This must have annoyed someone in the past so excuse me if this is a duplicate and I will remove it. Slashes across legends when using geom_bar can be annoying. e.g.: x <- c("a","b")y <- c(1,2)df <- as.data.frame(cbind(x,y))a <- ggplot(df,aes(x=x,y=y,fill=x))a + geom_bar(colour="black") + scale_fill_manual(values=c("white", "black"))When I use coloured bars I use this work around, plotting bars without colours first e.g.a + geom_bar() + geom_bar(colour="black",show_guide=FALSE) + scale_fill_manual(values=c("white", "black"))However when the fill is white this leaves an unsatisfying empty white box in the legend without a border. e.g.I have fixed this in the past manually using graphics software but now I think this must be of use to enough people to ask a question here. Can we make ggplot plot the legend with the black outline only but without the slash? 解决方案 this, a + geom_bar() + geom_bar(colour="black",show_guide=FALSE) + scale_fill_manual(values=c("white", "black")) + opts(legend.key = theme_rect(fill = 'black'))gave me this,thanks to this site.Alos, you get the same result using colour instead of fill (it might be argued that one is better than).a + geom_bar() + geom_bar(colour="black",show_guide=FALSE) +scale_fill_manual(values=c("white", "black")) +opts(legend.key = theme_rect(colour = 'black'))Important note: In modern versions of ggplot2 opts has been deprecated and replaced with theme, and theme_rect has been replaced by element_rect. 这篇关于ggplot传说中的斜线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!
