问题

I'm making plots using echarts4r. In my language, the separators for decimals and thousands are reversed from English, i.e., commas for decimals, dots for thousands. How can I accomplish this for my charts? Here's an example:

library(dplyr)
library(echarts4r)
my_data <- data.frame(x=1:3, y=c(1000,2000,2500))

e_charts(my_data, x = x) %>% e_bar(y) %>% e_tooltip()

I'd like both the y axis and tooltip to have dots instead of commas in numbers.

I'd prefer doing it via Javascript in formatter arguments since I'm doing some other manipulations for detailed tooltips, but I'm not sure what to write for this purpose.

  But I'd rather change the symbols than remove it.

library(dplyr)
library(echarts4r)
my_data <- data.frame(x=1:3, y=c(1000,2000,2500))

e_charts(my_data, x = x) %>% e_bar(y) %>% e_tooltip()

这里是调整 formatter 以获得所需输出的唯一方法：

library(dplyr)
library(echarts4r)
my_data <- data.frame(x = 1:3, y = c(100.23, 2000.21, 2500.12))

e_charts(my_data, x = x) %>%
  e_bar(y) %>%
  e_tooltip(
    formatter = htmlwidgets::JS(
      "function(params) {
         var value = params.value[1].toFixed(2).replace('.', ',');
         return value.toString().replace(/(\\d)(?=(\\d{3})+(?!\\d))/g, '$1.');
       }"
    )
  )

Here is ony way how to tweak `formatter` to get the desired output: 

library(dplyr)
library(echarts4r)
my_data <- data.frame(x = 1:3, y = c(100.23, 2000.21, 2500.12))

e_charts(my_data, x = x) %>%
e_bar(y) %>%
e_tooltip(
formatter = htmlwidgets::JS(
"function(params) {
var value = params.value[1].toFixed(2).replace('.', ',');
return value.toString().replace(/(\d)(?=(\d{3})+(?!\d))/g, '$1.');
}"
)
)
