Bar Chart Narrow Bars

20200428

ds %>%
  ggplot(aes(wind_dir_9am)) +
  geom_bar(width=0.5) +
  scale_y_continuous(labels=comma) +
  labs(x=vnames["wind_dir_9am"], y="Count")

The width of the bars can be specified, relative to the space allowed for each bar. Here we make the bars narrower using width=0.5 so as to be half width. This may help to make the plot look less dark.
