Unsure what's going wrong here but basically I want to create a boxplot filled a specific color using the following:
ggplot(iris %>%
+ filter(Species == "setosa"), aes(y= Sepal.Length)) +
+ geom_boxplot(coef = 7)+
+ scale_color_manual(values="cornflowerblue") +
+ labs(title="Sepal Length", y = "Length")+
+ theme_hc()
No matter what I try (fill/color ops in aes) I don't get color.
Also, how do I stop the x-axis from being continuous?
It depends on what you're looking for. If you are only creating a single boxplot, you can simply use fill and col outside of aes
library(ggplot2)
library(dplyr)
data(iris)
iris %>% filter(Species == 'setosa') %>%
ggplot(aes(y = Sepal.Length)) +
geom_boxplot(col = 'green', fill = 'green')
Note that col is the colour of the border while fill is the filling of the box. col=NA works by removing the colour around the boxplot.
But if you wish to get control over the colour with multiple groups, this has to be specified in 2 places
scale_colour_manual / scale_color_manual and scale_fill_manual to control the actual colours chosen for the fill and border respectively.iris %>%
ggplot(aes(y = Sepal.Length,
fill = Species,
col = Species)) +
geom_boxplot() +
scale_fill_manual(values = c(setosa = 'blue',
versicolor = 'yellow',
virginica = 'orange')) +
scale_colour_manual(values = c(setosa = 'purple',
versicolor = 'green',
virginica = 'black'))
Pointing to comments of @akrun this works:
ggplot(iris %>% filter(Species == "setosa"), aes(y= Sepal.Length)) +
geom_boxplot(coef = 7,fill='cornflowerblue')+
labs(title="Sepal Length", y = "Length")
fill = "cornflowerblue"inaes
