我有一个数据框,我试图在同一个图中绘制一条线和一条条。我还需要一个传奇。我得到了条形图以显示所需的颜色,但更多的是添加轮廓而不是颜色,它显示了我想要移除的y = 0的水平线。
任何帮助表示赞赏!
这是我的代码:
windows()
ggplot(data = rr, aes(x = date))+
geom_point(aes(y=value, colour="Nitrogen"))+
geom_line(aes(y=value, colour="Nitrogen"))+
facet_grid(depth~dose) +
geom_bar(data=rr,stat = "identity", position = position_dodge(width = 0.9),aes(x=date, y=rain100 ,colour="Rains"))+
theme(strip.text.x = element_text(size = 7, colour = "black", angle = 0),axis.text.x = element_text(angle=90,vjust=0.5,hjust=0.5, size=8))+
ylab("Soil nitrogen measured as nitrate, lb/ac and rains, 100ths of inch")+
scale_x_date(date_breaks = "1 month",date_labels = "%m-%d-%y")+
ggtitle("MR Ranch")+
ylim(0,350)+
scale_colour_manual("",
breaks=c("Nitrogen","Rains"),
values=c("black","blue"))
这是我的数据集(缩短版)

关键是使用填充而不是颜色。代码将生成警告但将正确显示。验证图例是否为预期结果。
库(GGPLOT2)
ggplot(data = rr, aes(x = date))+
geom_point(aes(y=value, fill="Nitrogen"), colour="black")+
geom_line(aes(y=value, fill="Nitrogen"), colour="black")+
facet_grid(depth~dose) +
geom_bar(data=rr,stat = "identity", position = position_dodge(width = 0.9),aes(x=date, y=rain100, fill="Rains") )+
theme(strip.text.x = element_text(size = 7, colour = "black", angle = 0),axis.text.x = element_text(angle=90,vjust=0.5,hjust=0.5, size=8))+
ylab("Soil nitrogen measured as nitrate, lb/ac and rains, 100ths of inch")+
scale_x_date(date_breaks = "1 month",date_labels = "%m-%d-%y")+
ggtitle("MR Ranch")+
ylim(0,350) +
scale_fill_manual(labels=c("Nitrogen","Rains"), breaks=c("Nitrogen","Rains"), values=c("black","blue"), name="")
所以看起来你想要一个直方图而不是一个条形图。所以我把geom_bar
换成了geom_histogram
。此外,我相信你正在获得这个传奇,因为你使用color
参数而不是fill
,它会给你一个大纲。试试这段代码:
ggplot(data = rr, aes(x = date)) +
geom_point(aes(y = value, colour = "Nitrogen")) +
geom_line(aes(y = value, colour = "Nitrogen")) +
facet_grid(depth ~ dose) +
geom_histogram(data= rr, stat = "identity", position = position_dodge(width = 0.9), aes(x = date, y = rain100 ,fill= "Rains")) +
theme(strip.text.x = element_text(size = 7, colour = "black", angle = 0), axis.text.x = element_text(angle = 90,vjust = 0.5, hjust = 0.5, size = 8)) +
ylab("Soil nitrogen measured as nitrate, lb/ac and rains, 100ths of inch") +
scale_x_date(date_breaks = "1 month", date_labels = "%m-%d-%y") +
ggtitle("MR Ranch")+
ylim(0,350)+
scale_colour_manual("",
breaks=c("Nitrogen","Rains"),
values=c("black","blue"))
