r语言 - Rshiny Highcharter我如何创建一个向下钻到另一个饼图的piechart ? &

Question

我看到的例子是向柱状图深入的柱状图。但在RShiny中，我似乎找不到一个饼状图可以深入到另一个饼状图的例子。

Answer 1

您可以在hc_drilldown()中指定type参数，如highcharter参考页面中的示例所示。

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)
