Let's flip some axes
First, we can practice rotating a plot. Provided is code that makes a bar plot of the number of cases of pertussis in the Americas region (AMR) in 1980. You will notice it's almost unreadable.
First, to help see patterns that may be in the data, reorder() the columns in descending order of cases.
Next, let's coord_flip() the axes to make it possible to read the country names.
This exercise is part of the course
Visualization Best Practices in R
Exercise instructions
reorder()the x-axis by descending order ofcases- Add
coord_flip()to the plot to swap x and y-axes.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
amr_pertussis <- who_disease %>%
filter( # filter data to our desired subset
region == 'AMR',
year == 1980,
disease == 'pertussis'
)
# Set x axis as country ordered with respect to cases.
ggplot(amr_pertussis, aes(x = ___, y = cases)) +
geom_col() +
# flip axes
