ggplot(mtcars)+
geom_point(aes(wt,mpg, size = disp,color = color))+
scale_color_identity(guide ='legend')
My main goal is to color elements differently in my plot. To do so, I manually
added an extra column with the desired color for each category
:
mtcars$color[mtcars$carb = 4] = '#F98866'
mtcars$color[mtcars$carb = 3] = '#68829E'
mtcars$color[mtcars$carb = 2] = '#FF420E'
mtcars$color[mtcars$carb = 1] = '#89DA59'
p <- ggplot(mtcars) +
geom_point(aes(wt, mpg,
size = disp,
color = mtcars$color))# + scale_color_manual(values = mtcars$color)
But when I run the above code, I get this as an output:
Instead of my specified
colors, I get the preset ggplot
colors.
But if I uncomment the last line, I partially get what I'm looking for--only one of the colors I wanted.
How can this problem be resolved?
