问题描述
我想将图例标题 sex 右移一点到图例框的水平中心。我试过主题和 guide_legend ,但失败了。这两种方式不会改变图例的标题位置。
#来自www.cookbook-r的示例数据/图/传说_(ggplot2)/ df1 < - data.frame( sex = factor(c(女,女,男,男)),时间=因子(c(午餐,晚餐,午餐,晚餐),水平= c(午餐,晚餐)), total_bill = c(13.53,16.81 ,16.24,17.42)) library(ggplot2)p < - ggplot(data = df1,aes(x = time,y = total_bill,group = sex,shape = $ b#不变p + theme(legend.title = element_text(hjust = 0.5))p + guides(color = guide_legend(title.hjust = 0.5))另外,I我使用ggplot2_2.2.0。
解决方案您需要 legend.title.align 而不是 legend.title :
p +主题title.align = 0.5)
I want to move the legend title sex a little right to the horizontal center of legend box. I tried theme and guide_legend but failed. Both ways won't change the legend title position.
# example data from www.cookbook-r/Graphs/Legends_(ggplot2)/ df1 <- data.frame( sex = factor(c("Female","Female","Male","Male")), time = factor(c("Lunch","Dinner","Lunch","Dinner"), levels=c("Lunch","Dinner")), total_bill = c(13.53, 16.81, 16.24, 17.42) ) library(ggplot2) p <- ggplot(data=df1, aes(x=time, y=total_bill, group=sex, shape=sex, colour=sex)) + geom_line() + geom_point() # no change p + theme(legend.title = element_text(hjust = 0.5)) p + guides(color=guide_legend(title.hjust=0.5))In addition, I am using ggplot2_2.2.0.
解决方案You need legend.title.align rather than legend.title:
p + theme(legend.title.align=0.5)更多推荐
