Create geoFacet Echart — e_geoFacet • echarts4r

generates a faceted chart using matrix functionality. Provides similar functionality to e_facet(). Similar to geoFacet package. Timeline is NOT supported.

Usage

e_geoFacet(
  e,
  rows,
  cols,
  grid,
  legend = TRUE,
  legend_pos = "top",
  legend_space = "10%",
  margin_trbl = c(t = "8%", r = "5%", b = "8%", l = "8%"),
  ...
)

Arguments

e: An echarts4r object as returned by e_charts or a proxy as returned by echarts4rProxy.
rows, cols: Provide integer values for the number of rows and columns in the matrix grid
grid: A custom grid containing row,col positions and name. Or a string containing the name of a premade geoFacet grid from the geoFacet package.
legend: Whether chart contains a legend. Defaults to TRUE.
legend_pos: Position of the legend. One of "top", "right", "bottom", "left". Determines to which side the `legend_space` argument applies.
legend_space: Space between legend and plot area. Supports integers(pixels) or strings(percent of parent cell).
margin_trbl: Adjusts the size of the outside margin around the plotting area. Default is `c(t = "15 integers(pixels) or strings(percent of parent cell) To change only e.g. two sides `c("r" = 8, "l" = 8)` could be used, other sides will use defaults.
...: Any other option to pass, check See Also section.

Examples

if (require("geofacet", quietly = TRUE)) {
  library(geofacet)

  df <- data.frame(group = rep(letters[1:6], each = 20),
  date = seq(from = as.Date("2025-01-01"),
             to = as.Date("2025-01-20"), by = "day"),
  temp = sample(c(10:20), size = 60, replace = TRUE))
  grid <- data.frame(name = unique(df$group), row = c(1:6), col = c(1:6))

  df |>
    group_by(group) |>
    e_chart(date) |>
    e_line(temp, symbol = "none") |>
    e_x_axis(splitNumber = 2) |>
    e_y_axis(splitNumber = 2) |>
    e_geoFacet(legend = FALSE,
               grid = grid,
               margin_trbl = c("t"="25%"),
               left = "5%",
               width = "90%") |>
    e_title(text = "Group Temps")


  tem <- data.frame(state.x77)
  sta <- cbind(state.name, tem)
  colnames(sta)[1] <- "State"

  sta |>
    group_by(State) |>
    e_charts(Population) |>
    e_scatter(Income) |>
    e_geoFacet(grid = "us_state_grid1") |>
    e_tooltip()
