在工具提示echarts4r中显示额外的变量-Displayingextravariablesintooltipsecharts4r

A bit hacky, but you can pass in a string with the data you wish to display as the data name, then parse it inside the function. For example,

这有点麻烦，但是您可以将希望显示为数据名的数据传入一个字符串，然后在函数中解析它。例如,

mtcars %>%  
  tibble::rownames_to_column("model") %>%
  mutate(model = paste(model, qsec, sep = ",")) %>%
  e_charts(wt) %>% 
  e_scatter(mpg, bind = model) %>%
  e_tooltip(formatter = htmlwidgets::JS("
                                        function(params){
                                          var vals = params.name.split(',')
                                          return('' + vals[0] + 
                                          '
wt: ' + params.value[0] + 
                                          '
mpg: ' +  params.value[1]) +
                                          '
qsec: ' + vals[1]}  "))

which gives you

Does this give the intended effect?

这会产生预期的效果吗?

library(dplyr)
library(echarts4r)
mtcars %>%  
  tibble::rownames_to_column("model") %>% 
  e_charts(wt) %>% 
  e_scatter(mpg, qsec, bind=model) %>% # pass qsec as size
  e_tooltip(formatter = htmlwidgets::JS("
                                        function(params){
                                        return('' + params.name + 
                                        '
wt: ' + params.value[0] + 
                                        '
mpg: ' +  params.value[1] +
                                        '
qsec: ' +  params.value[2] )   }  ")) # size = third value
