我如何在R中的高位宪章中更改图例的比例？

Question

这里是highcharter软件包网站上的一些开源代码，详细说明了如何使用hcmap加载到地图中。

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")) 

我想知道是否/如何更改右下角图例的比例。如果我想要对数刻度或一些自定义值怎么办？有没有办法用这个软件包做到这一点？

对于对数刻度，尝试用管道传输到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：也可以自定义色阶，请参见https://www.highcharts.com/forum/viewtopic.php?t=33569。
