Question

How to provide color to ggplot scatter chart depending on field value?

I tried below code but i want different colors and not in the same blue scale. What to do?

ggplot(mpg, aes(cty,hwy,col= km$cluster)) + geom_point()

Answer 1

cyl is a continuous value field, so it cannot show different colors

One way is to change the color scale to Viridis using scale_col_continuous(type = "Viridis")

Or change the field to a discrete scale.
