Correct ugly label positions
The labels still kind of overlap with the lines in the dot plot. Use a conditional hjust
aesthetic in order to better place them, and change their appearance.
This exercise is part of the course
Communicating with Data in the Tidyverse
Exercise instructions
- Give the
hjust
aesthetic in thegeom_text()
function call a value of1.4
, if it concerns the label for the year"2006"
, and-0.4
if not. Use theifelse()
function for this. - Change font size, family and color to
3
,"Bookman"
and"gray25"
respectively, also in thegeom_text()
call, but outside of theaes()
function since these values are not data-driven.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Save plot into an object for reuse
ilo_dot_plot <- ggplot(ilo_data) +
geom_path(aes(x = working_hours, y = country),
arrow = arrow(length = unit(1.5, "mm"), type = "closed")) +
# Specify the hjust aesthetic with a conditional value
geom_text(
aes(x = working_hours,
y = country,
label = round(working_hours, 1),
hjust = ifelse(___)
),
# Change the appearance of the text
___ = ___,
___ = "___",
___ = "___"
)
