11.6 Bar Chart Dodge


ds %>%
  ggplot(aes(x=wind_dir_3pm, fill=rain_tomorrow)) +
  geom_bar(position="dodge") +
  scale_y_continuous(labels=comma) +  
  labs(x=vnames["wind_dir_3pm"], y="Count", fill="Rain") +

A stacked bar chart is produced when a fill is provide through the aesthetics, as in Section 11.17. However the top bars can be difficult to compare amongst the columns. Instead of stacking the bars we can dodge the bars with the position="dodge" option to ggplot2::geom_bar().
