Description

Defines the GeomTimeline ggplot2 geom. It is recommended to use the geom_timeline function to create these layers. The only required aesthetic is x which determines where along the line to place the circles. The optional aesthetics color, size, and alpha define the color, radius and transparency of the circle, and the optional aesthetic y can be used for making multiple stratified timelines.

Usage

GeomTimeline

Format

An object of class GeomTimeline (inherits from Geom, ggproto, gg) of length 6.

Value

Geom* object for rendering timelines on plots

Examples

## Not run: 
# All deadly earthquakes in JAPAN, CHINA and NEPAL since 2000

data <- eq_clean_data() %>%
     dplyr::filter(!is.na(TOTAL_DEATHS)) %>%
     dplyr::select(DATE, YEAR, COUNTRY, REGION, LONGITUDE, LATITUDE, MAG, TOTAL_DEATHS) %>%
     tidyr::drop_na() %>%
     dplyr::filter(YEAR > 1999, COUNTRY %in% c("JAPAN", "CHINA","NEPAL"))

# Plot Timeline

ggplot2::ggplot() +
    ggplot2::layer(geom = GeomTimeline,
                   mapping = aes(x = data$DATE,
                                 y = data$COUNTRY,
                                 size = data$MAG,
                                 color = data$TOTAL_DEATHS),
                   data = data,
                   stat = 'identity',
                   position = 'identity',
                   show.legend = NA,
                   inherit.aes = TRUE,
                   params = list(na.rm = FALSE))
