This geom charts a timeline of earthquakes for a given country with points along the timeline for each earthquake. The size of the point inicates the magnitude of the earthquake, while the color indicates the number of deaths. The date (x) is a required aesthetic. The country (y) is optional.

Usage

geom_timeline(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  ...
)

Examples

## Not run: 
 df <- df_earthquakes %>% filter(COUNTRY %in% c("GREECE", "USA"), YEAR > 2002)
 ggplot(df, aes(x = date, y = COUNTRY,
                color = as.numeric(TOTAL_DEATHS),
                size = as.numeric(EQ_PRIMARY),
                label = CLEAN_LOCATION_NAME)) +
   geom_timeline() +
   labs(size = "Richter scale value", color = "# deaths") +
   ggplot2::theme(panel.background = ggplot2::element_blank(),
         legend.position = "bottom",
         axis.title.y = ggplot2::element_blank()) +
   ggplot2::xlab("DATE")
