ggplot2 显示离散变量的多个点

Question

I want to show different countries Index scores on the y axis for a metric column in my dataframe(discrete variable) and color the points based on the country.

The snippet of dataframe, test:

Countries	Metric	Index Score
UK	Equity	99.1
USA	Equity	6.9
France	Equity	75.4

ggplot(test,aes( x= Metric , y= "Index Score", color = Countries)) + 
geom_point()

The output currently looks like this: all points are on top of each other and not dispersed

Answer 1

Do y = `Index Score` , a string is not valid.
