geom_point - change colour of variable

Question

I coloured my data by "Full Bath", however it is a similar shade & unclear.

I am trying to change the colour by variable of "Full Bath" to be more clear.

Could anyone help :)

This is what I have:

data %>%
  ggplot(aes(Sale.Price, Total.Bsmt.SF)) +
  geom_point(aes(colour = Full.Bath)) + geom_smooth()

You need two curves instead of one and each in a different color, is that right ? — Yacine Hajji, Dec 05 '22 at 10:37
thanks for getting back so fast! I am doing a scatter plot and am finding it very difficult to explain it so I attached a photo. Colours 2&3 are very similar and I am trying to change them! Apologies and thanks!! — SeanMc152, Dec 05 '22 at 12:02

To manually change the colors, you can use scale_color_manual, as follows:

### Simulation of data
set.seed(1)
data <- data.frame(Sale.Price=rnorm(100, 100, 10), 
                   Total.Bsmt.SF=rnorm(100, 10, 1),
                   Full.Bath=rep(c("a", "b", "c", "d", "e"), 20))

### Plot data
data %>%
  ggplot(aes(x = Sale.Price, y = Total.Bsmt.SF)) +
  geom_point(aes(colour = Full.Bath)) + 
  geom_smooth() + 
  scale_color_manual(values=c("#84d58d", "#84c1d5", "#9e84d5", "#d584b0", "#d5be84"))
