例如,我有如下数据,
population=rep(c("High", "Low"), time=5)
year=rep(c("2020_H","2020_L","2020_O","2021_L","2021_O"), each=2)
x=c(10,20,30,40,50,60,70,80,90,100)
y=c(15,25,35,45,55,75,100,120,125,145)
dataA=data.frame(population,year,x,y)
population year x y
1 High 2020_H 10 15
2 Low 2020_H 20 25
3 High 2020_L 30 35
4 Low 2020_L 40 45
5 High 2020_O 50 55
6 Low 2020_O 60 75
7 High 2021_L 70 100
8 Low 2021_L 80 120
9 High 2021_O 90 125
10 Low 2021_O 100 145
ggplot(data=dataA, aes(x=x, y=y))+
stat_smooth(method='lm', linetype=1, se=FALSE, formula=y~x, linewidth=0.5,
color="dark red") +
geom_point(aes(fill=year, shape=population), color="black", size=4) +
scale_fill_manual(values= c("Dark red","Dark blue", "Orange", "purple", "dark green"))+
scale_shape_manual(values=c(21,24))+
scale_x_continuous(breaks=seq(0,100,20),limits=c(0,100))+
scale_y_continuous(breaks=seq(0,150,50),limits=c(0,150))+
guides(shape="none") +
theme_classic(base_size=16, base_family="serif")+
theme(legend.position=c(0.8, 0.2),
legend.title=element_blank(),
legend.key=element_rect(color=alpha("grey",.05), fill=alpha("grey",.05)),
legend.background= element_rect(fill=alpha("grey",.05)),
axis.line=element_line(linewidth=0.5, colour="black"))+
windows(width=5.5, height=5)
我生成了一张图表。我为人口提供了不同的形状,为年份提供了不同的颜色。然后,我使用
guides(shape="none")
隐藏形状的图例。但是,填充图例没有提供正确的颜色索引。我想在一年的传说中展示不同的颜色。
你能告诉我怎么做吗?
总是非常感谢!
