Register map — e_map_register • echarts4r

Usage

e_map_register(e, name, json, ...)

e_svg_register(e, name, svg)

e_map_register_p(
  name,
  json,
  async = FALSE,
  session = shiny::getDefaultReactiveDomain()
)

e_map_register_ui(name, json, async = FALSE)

Arguments

e: An echarts4r object as returned by e_charts.
name: Name of map, to use in e_map.
json, svg: Geojson, or SVG.
...: Additional options passed to registerMap.
async: Whether to read the file asynchronously.
session: A valid Shiny session.

Details

e_map_register_p is not truly a proxy as it does not require a chart to function. While the function e_map_register_ui is meant to register the map globally in the Shiny UI, not that then json must be accessible from the UI (generally www folder).

Examples

if (FALSE) {
json <- jsonlite::read_json("https://echarts.apache.org/examples/data/asset/geo/USA.json")
