R Shiny Highcharter 如何创建一个向下钻取到另一个饼图的饼图？

Question

我见过的示例是向下钻取到条形图的条形图。但是我似乎找不到在 RShiny 中深入到另一个饼图的饼图示例。

您可以在 hc_drilldown() 中指定 type 参数，如编辑 highcharter reference page 中的示例所示。

library(highcharter)
library(dplyr)
library(purrr)

df <- tibble(
    name = c("Animals", "Fruits"),
    y = c(5, 2),
    drilldown = tolower(name)
)

df
#> # A tibble: 2 x 3
#>   name        y drilldown
#>   <chr>   <dbl> <chr>
#> 1 Animals     5 animals
#> 2 Fruits      2 fruits

hc <- highchart() %>%
    hc_title(text = "Basic drilldown") %>%
    hc_xAxis(type = "category") %>%
    hc_legend(enabled = FALSE) %>%
    hc_plotOptions(
        series = list(
            boderWidth = 0,
            dataLabels = list(enabled = TRUE)
        )
    ) %>%
    hc_add_series(
        data = df,
        type = "pie",
        hcaes(name = name, y = y),
        name = "Things",
        colorByPoint = TRUE
    )

dfan <- data.frame(
    name = c("Cats", "Dogs", "Cows", "Sheep", "Pigs"),
    value = c(4, 3, 1, 2, 1)
)

dffru <- data.frame(
    name = c("Apple", "Organes"),
    value = c(4, 2)
)


dsan <- list_parse2(dfan)

dsfru <- list_parse2(dffru)

hc <- hc %>%
    hc_drilldown(
        allowPointDrilldown = TRUE,
        series = list(
            list(
                id = "animals",
                type = "pie",
                data = dsan
            ),
            list(
                id = "fruits",
                type = "pie",
                data = dsfru
            )
        )
    )
print(hc)
