syncWith: Synchronize multiple maps

In rte-antares-rpackage/leaflet.minicharts: Mini Charts for Interactive Maps

Synchronize multiple maps

Description

This function can be used when multiple leaflet maps are displayed on the same view (for instance in a shiny application or a Rmarkdown document) and one wants to synchronize their center, zoom and time.

syncWith() can also be used with basic leaflet maps to synchronize only their zoom and center.

Usage

syncWith(map, groupname)

Arguments

map	A leaflet map object created with leaflet.
groupname	Character string. All maps that use the same group name will be synchronized.

Value

The modified leaflet map object.

Examples

if (require(manipulateWidget) & require(leaflet)) {

  # Synchronize zoom and center of basic maps.
  basicMap1 <- leaflet() %>% addTiles() %>% syncWith("basicmaps")
  basicMap2 <- leaflet() %>% addTiles() %>% syncWith("basicmaps")
  combineWidgets(basicMap1, basicMap2)

  # Synchronize time step of two maps that represent the evolution of some
  # variable.
  map1 <- leaflet() %>% addTiles() %>%
    addMinicharts(0, 40, chartdata = 1:10, time = 1:10) %>%
    syncWith("maps")
  map2 <- leaflet() %>% addTiles() %>%
    addMinicharts(0, 40, chartdata = 10:1, time = 1:10) %>%
    syncWith("maps")
  combineWidgets(map1, map2)

}
