echarts4r: horizontal jitter with discrete x axis

In an echarts4r scatter plot, is it possible to add horizontal jitter with a discrete x axis?

library(echarts4r)
library(tidyverse)

df <- tibble(x = c("a", "a", "b", "b", "c", "c"),
       y = c(1, 2, 3, 3, 4, 5),
       z = c(1, 2, 3, 3, 4, 5))

df |> 
  e_charts(x) |>
  e_scatter(y, symbol_size = 15) |>
  e_scatter(z, symbol_size = 15, symbol="diamond", jitter_amount = 1) |>
  e_color(
    c("red", "blue")
  )

The jitter option adds vertical jitter (blue diamonds) instead of the desired horizontal jitter.

You could set x_index = 1 to your e_scatter and use a second x axis with should not be shown to get the jitter of your points like this:

library(echarts4r)
library(tidyverse)

df <- tibble(x = c("a", "a", "b", "b", "c", "c"),
             y = c(1, 2, 3, 3, 4, 5),
             z = c(1, 2, 3, 3, 4, 5))

df |> 
  e_charts(x) |>
  e_scatter(y, symbol_size = 15) |>
  e_scatter(z, symbol_size = 15, symbol="diamond", jitter_amount = 2, x_index = 1) |>
  e_color(
    c("red", "blue")
  ) |>
  e_x_axis(index = 1, show=F)
