Bar Chart Wide Bars

20200428

ds %>%
  ggplot(aes(wind_dir_9am)) +
  geom_bar(width=1) +
  scale_y_continuous(labels=comma) +
  labs(x=vnames["wind_dir_9am"], y="Count")

The bars of a bar chart can be made to touch by specifying a full width with width=1. Also compare this plot to that in Section 10.7 where the counts are manually generated and ggplot2::geom_col() is used to plot the bars.
