我一直在尋找這一段時間。我的傳奇正在走出圖表區域。有沒有辦法在ggplot2中垂直對齊圖例?ggplot vertical justify legend
ggplot(x, aes(x=TimeStamp, y=Average, colour=Host, group=Host))
+ geom_point(size=0.4)
+ geom_smooth(method="lm", se=FALSE, size=1)
+ theme_bw()
+ xlab("Date")
+ ylab("% CPU Utilization")
+opts(axis.title.x = theme_text(face="bold", colour="#990000"), axis.text.x = theme_text(angle=90), axis.title.y = theme_text(face="bold", colour="#990000", angle=90),legend.key.size = unit(0.8, 'lines'))
+ ylim(0, 100)
+ scale_x_date(breaks = "1 week", minor_breaks = "1 day", labels=date_format("%b-%d-%y"))
+ opts(legend.text = theme_text(colour = 'black',size = 10))
+ labs(colour = "Servers")
+ guides(col=guide_legend(nrow=30))
是不是這與你的[上一個問題](http://stackoverflow.com/q/12202683/420055)(在這種情況下,你可以簡單地更新它,而不是發佈一個新的)? – chl
