散点图上的彩色线 - R
Colour line on scatter plot - R
我为阿根廷和巴西绘制了二氧化碳排放散点图。我怎样才能让它们有不同的颜色？目前它都是绿色的。
谢谢

df%>%
dplyr:: filter(Country %in% c("Argentina", "Brazil")) %>%
filter(Year<=2019 & Year>=1950) %>%
ggplot(aes(x = Year, y = CO2_annual_tonnes)) +
geom_point(na.rm =TRUE, shape=20, size=2, colour="green") +
labs (x = "Year", y = "CO2Emmissions (tonnes)")
试试这个：
library(ggplot2)
library(dplyr)
df%>%
dplyr:: filter(Country %in% c("Argentina", "Brazil")) %>%
filter(Year<=2019 & Year>=1950) %>%
ggplot(aes(x = Year, y = CO2_annual_tonnes, colour=factor(country))) +
geom_point(na.rm =TRUE, shape=20, size=2) +
labs (x = "Year", y = "CO2Emmissions (tonnes)")
