Two different tooltips formatter for different axis

[egoipse]

Hi!

Great package. Thanks for the hard work.

Is there any chance to get different formatter configuration for tooltips in charts with more than one x or y axis?

Reprex:

library(echarts4r)

read.csv("https://raw.githubusercontent.com/selva86/datasets/refs/heads/master/BostonHousing.csv") |>	
  e_chart(rm) |>
  e_scatter(tax) |>
  e_bar(dis, y_index = 1) |>
  e_x_axis(
    formatter = e_axis_formatter(style = "decimal")
  ) |>
  e_y_axis(
    formatter = e_axis_formatter(style = "currency", currency = "USD")
  ) |>
  e_tooltip(
    "axis",
    formatter = e_tooltip_pointer_formatter(style = "currency", currency = "USD")
  )

The code generates the following chart:

Since "tax" is currency data, the style for e_tooltip in formatter was set to "currency". However, the tooltip also shows the currency style for "dis" data, which is not.

Any chance to set one formatter style for "tax" and another one for "dis" (in this case, "decimal")?

As far as I read on documentation, JS is the way to go. Any chance to do it just with R?

Thanks in advance for the answer!
