将 Highcharter 条形图中分组变量的某些值设置为默认取消选择

Question

我希望在堆叠式 Highcharter 条形图中我的分组变量的某些值在默认情况下被取消选择。我知道使用 hc_add_series 我可以设置 visible = FALSE 但我不会以这种方式生成我的图表。

这是一个示例数据集：

responses <- c('Pro','Against','Neutral','Resigned/Accepting','Not Specified')
constituents <- c('dual degree','law only','undergrad only','friend','parent only')
indiv <- rep(1:50)
Name.Change <- sample(responses,50,replace = TRUE)
constituent.type <- sample(constituents,50,replace = TRUE)

demo <- as.data.frame(cbind(indiv,Name.Change,constituent.type))

这是图表

demo %>% 
  group_by(constituent.type,Name.Change) %>%
  summarise(count = n()) %>%
  hchart(type = "bar",
         hcaes(y = count,
               x = constituent.type,
               group = Name.Change)) %>%
  hc_plotOptions(bar = list(stacking = "percent")) %>%
  hc_tooltip(shared = TRUE)

生成的图表选择了 Name.Change 的所有值，并且可以根据需要取消选择每个值。但是，我希望默认情况下取消选择某些值（例如“中性”和“未指定”），这样在呈现图表后，您必须单击图例中的该值才能显示在图表上.

我认为最好用chart.events.load来做，然后你可以为此编写自己的自定义JS函数： https://api.highcharts.com/highcharts/chart.events.load

在这里你可以看到如何做到这一点：

responses <- c('Pro','Against','Neutral','Resigned/Accepting','Not Specified')
constituents <- c('dual degree','law only','undergrad only','friend','parent only')
indiv <- rep(1:50)
Name.Change <- sample(responses,50,replace = TRUE)
constituent.type <- sample(constituents,50,replace = TRUE)
demo <- as.data.frame(cbind(indiv,Name.Change,constituent.type))
demo %>% 
  group_by(constituent.type,Name.Change) %>%
  summarise(count = n()) %>%
  hchart(type = "bar",
         hcaes(y = count,
               x = constituent.type,
               group = Name.Change)) %>%
  hc_chart(events = list(load = JS("function() {
  var chart = this;
  chart.series[1].setVisible(false)
  chart.series[2].setVisible(false)
  }"))) %>%
  hc_plotOptions(bar = list(stacking = "percent")) %>%
  hc_tooltip(shared = TRUE)
