使用下面的代码,我可以生成我想要的图形,但是当我尝试更改scale_color_manual部分中的图例标签时,仅显示第二个图例的线型变量
原始代码:
set.seed(124)
DF <- data.frame(values=rnorm(1000,500,200),type=sample(LETTERS[1:5],1000,T))
ggplot(DF, aes(x=values, color=type, linetype=type)) +
stat_ecdf(size=1, n=750, show_guide=T) +
xlab(expression('Index Value')) +
ylab("Cumulative Density") +
ggtitle(expression('All Index Values')) +
scale_x_continuous(expand = c(0,0)) +
scale_y_continuous(expand = c(0,0)) +
theme(text = element_text(size=20),
plot.title = element_text(size=30,face="bold",vjust=1),
axis.title.x=element_text(size=20,face="bold",vjust=0,hjust=0.5),
axis.title.y=element_text(size=20,face="bold",vjust=1.0,hjust=0.5),
legend.position = c(0.85, 0.25),
legend.text.align = 0,
legend.box = 'horizontal',
legend.margin = unit(45.0, 'line'),
legend.text=element_text(size=28,vjust=0,hjust=0),
legend.title=element_blank(),
legend.key=element_blank(),
legend.key.height = unit(1.5, 'line'),
legend.key.width = unit(1.5, 'line'),
panel.background = element_rect(fill = "white")) +
scale_color_manual(values=c('grey25','grey35','grey45','grey55','grey65'))
scale_color_manual(values=c('grey25','grey35','grey45','grey55','grey65'),
labels=c(expression(TI[c]),expression(TI[p]),
expression(TI[d]),expression(TI[l]),
expression(TI[w])))
新剧情:
如何设置图例的标签而不生成两个单独的图例,一个用于颜色,另一个用于线型?
