Violin Plot Faceted Location



ds %>%
  mutate(year=factor(format(ds$date, "%Y"))) %>%
  filter(location %in% (ds$location %>% unique %>% sample(12))) %>%
  sample_frac(0.1) %>%
  ggplot(aes(x=year, y=max_temp, fill=year)) +
  geom_violin() +
  geom_boxplot(width=.5, position=position_dodge(width=0)) +
  theme(legend.position="none") +
  theme(axis.text.x=element_text(angle=45, hjust=1)) +
  labs(x="Year", y=vnames["max_temp"]) +

We can readily split the plot across the locations. Things get a little crowded, but we get an overall view across all of the different weather stations. Notice we also rotated the x-axis labels so that they don't overlap.

We can immediately see one of the issues with this dataset, noting that three weather stations have fewer observations that then others.

Various other observations are also interesting. Some locations have little variation in their maximum temperatures over the years.
