如何更改 R 中 highcharter 中图例的比例？

Question

这是来自 highcharter 包网站的一些开源代码，详细说明了如何使用 hcmap 加载地图。

library(highcharter)

# produces the following map inline

hcmap("countries/us/us-all", data = data_fake, value = "value",
      joinBy = c("hc-a2", "code"), name = "Fake data",
      dataLabels = list(enabled = TRUE, format = '{point.name}'),
      borderColor = "#FAFAFA", borderWidth = 0.1,
      tooltip = list(valueDecimals = 2, valuePrefix = "$", valueSuffix = " USD"))

我想知道的是whether/how我可以改变右下角图例的比例。如果我想要对数刻度或一些自定义值怎么办？有没有办法用这个包做到这一点？

对于对数刻度，尝试通过管道传输到 hc_colorAxis(type = "logarithmic"):

library(highcharter)
library(dplyr)
data("USArrests", package = "datasets")
USArrests <- mutate(USArrests, `woe-name` = rownames(USArrests))
set.seed(1)
data_fake <- tibble(test = sample(1:300000, 50, replace = TRUE),
         `woe-name` = USArrests$`woe-name`)

hcmap(map = "countries/us/us-all", data = data_fake,
  joinBy = "woe-name", value = "test", name = "woe-name",
  dataLabels = list(enabled = TRUE, format = '{point.name}'),
  borderColor = "#FAFAFA", borderWidth = 0.1,
  tooltip = list(valueDecimals = 2, valuePrefix = "$", valueSuffix = " USD")
  ) %>%  hc_colorAxis(type = "logarithmic")

编辑： 自定义色标也是可能的，参见 https://www.highcharts.com/forum/viewtopic.php?t=33569。
