If you have used ggplot2, you probably wondered how to make all columns the same width.
You might have created a plot such as this one.
Here’s how to do it with one additional line to the usual ggplot statements.
ggplot(total_head_trauma_5) +
geom_col(
aes(
x = cause_of_injury, y = loss_of_consciousness_length,
fill = book_title
),
# not this
# position = "dodge"
# but this
position = position_dodge(preserve = "single")
+
) labs(
x = "Cause of injury", y = "Loss of consciousness length",
title = "Top five causes of injury in Tintin books"
)
We can center the columns and make columns in the same category more separated, and also make it a bit nicer.
ggplot(total_head_trauma_5) +
geom_col(
aes(
x = cause_of_injury, y = loss_of_consciousness_length,
fill = book_title
),position = position_dodge2(preserve = "single")
+
) labs(
x = "Cause of injury", y = "Loss of consciousness length",
title = "Top five causes of injury in Tintin books"
+
) theme_minimal() +
scale_fill_manual(
values = tintin_colours$the_black_island, name = "Book"
+
) coord_flip()
