How do I create a scatter-plot in ggplot() with each points coloured manually? The necessary colours are given in my dataframe.

> head(df) x y col 1 0.72 2757 #2AAE89 2 0.72 2757 #2DFE83 3 0.72 2757 #40FE89 4 0.70 2757 #28FE97 5 0.86 2757 #007C7D 6 0.75 2757 #24FEA1

The colour of the points must be exactly as given in the dataframe

  • There's nothing I can do about the duplicated post - consider checking the linked answers. You cannot change your question once it is answered - that's how the site works. It wastes the efforts of the answerers Commented Aug 11, 2019 at 14:46

Luckily there is a relatively easy solution by using scale_colour_identity(), see the following example:

library(ggplot2) z <- " x y z col 1 0.72 2757 86 #2AAE89 2 0.72 2757 86 #2DFE83 3 0.72 2757 86 #40FE89 4 0.70 2757 82 #28FE97 5 0.86 2757 26 #007C7D 6 0.75 2757 79 #24FEA1" df <- read.table(text = z, header = T) ggplot(df, aes(x, y, colour = col)) + geom_point() + scale_colour_identity()

EDIT: I made a mistake in loading in the data, but the plotting syntax is still valid.
