geom_timeline: Timeline of Earthquakes

In DYZI/Earthquake: "earthquake: Visualizing NOAA's Significant Earthquakes"

Description

geom_timeline shows a timeline of NOAA Significant earthquakes, plotting individual countries along the y-axis and dates along the x-axis. The size of the points is relatative to the earthquakes' magnitude, and the color is related to the total number of deaths.

Usage

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

Arguments

mapping	See ggplot2 layer
data	See ggplot2 layer
stat	See ggplot2 layer
position	See ggplot2 layer
na.rm	See ggplot2 layer
show.legend	See ggplot2 layer
inherit.aes	See ggplot2 layer
...	other arguments passed on to layer.

Details

It is highly recommended that this geom is not used in isolation. For best results, use it with the eq_timeline wrapper function.

Aesthetics

geom_timeline undertands the following aesthetics (required aesthetics are in bold):

• x: recommend DATE

• y: recommend COUNTRY

• size: recommend EQ_PRIMARY

• color: recommend TOTAL_DEATHS

• alpha

• shape

• stroke

• fill

Examples

library(dplyr); library(ggplot2)
quakes <- eq_load_clean_data()

quakes %>%
  dplyr::filter(COUNTRY %in% c('USA', 'UK')) %>%
  dplyr::filter(DATE > '2000-01-01') %>%
  ggplot() +
  geom_timeline(aes(x = DATE, y = COUNTRY, color = TOTAL_DEATHS,
                    size = EQ_PRIMARY)) +
  scale_size_continuous(name = 'Richter scale value') +
  scale_color_continuous(name = '# of Deaths') +
  theme_eq()
