Examples

# You can change the markers `roboplot()` uses by using `set_markers()`.

  dplyr::filter(Suunta == "Tuonti", Alue == "Venäjä") |>
  dplyr::group_by(Alue) |>
  dplyr::mutate(sd = sd(value)) |>

  roboplot(
    Alue,
    plot_type = "scatter",
    plot_mode = "scatter",
    markers = set_markers(symbol = "diamond", size = 12)

# You cannot control the markers by trace, but you can use `pattern` in `roboplot()`
# with markers if you have set 'plot_mode' to "scatter+line".
