在 R Highchart 中手动重新排序条形图

Question

我是 highcharter 的新手，我正在尝试手动重新排序条形图的类别，但我似乎无法立即找到解决方案。我尝试使用 fct_relevel 重新排序，但它不起作用

我的代码看起来像这样：

library(highcharter)
library(tidyverse)

df <- data.frame(x= rep(c("john", "Luke", "Tom", "Sarah", "Laura", "Stacy"), each = 2), 
                 y = round(runif(12, min=0, max=100)),
                 z = rep(c(2020, 2021), each = 6)
                 )

df %>% hchart("bar", hcaes(x = x, y = y, group = z))

enter image description here

基本上，我希望能够手动设置轴类别的顺序并根据我的喜好重新定位它们，例如将 Luke 放在最后，将 Stacy 放在第一位。

有人对此有解决方案吗？

Answer 1

您可以通过按所需顺序设置因子水平并排列数据集来获得所需结果：

library(highcharter)
library(tidyverse)

set.seed(123)

df <- data.frame(x= rep(c("john", "Luke", "Tom", "Sarah", "Laura", "Stacy"), each = 2), 
                 y = round(runif(12, min=0, max=100)),
                 z = rep(c(2020, 2021), 6)
)

df %>% 
  mutate(z = as.character(z),
         x = fct_relevel(x, "Luke", after = 0),
          x = fct_relevel(x, "Stacy", after = Inf)) %>% 
  arrange(x) %>%
  hchart("bar", hcaes(x = x, y = y, group = z))

Answer 2

一种简单的方法是使用 hc_axis 定义类别的顺序。

library(highcharter)
library(tidyverse)

df %>%
  hchart("bar", hcaes(x = x, y = y, group = z)) %>%
  hc_xAxis(categories = list("Stacy", "john", "Tom", "Sarah", "Laura", "Luke"))

输出

数据

set.seed(123)

df <-
  data.frame(x = rep(c(
    "john", "Luke", "Tom", "Sarah", "Laura", "Stacy"
  ), each = 2),
  y = round(runif(12, min = 0, max = 100)),
  z = rep(c(2020, 2021), 6))
