基于点颜色的R highcharter图例

Question

我有下面的代码和图表

xlat

对于图例，目前它是“系列1”，我想让它成为每个点颜色的点图例，即绿色，橙色和红色。并且还可以自定义图例文本。

传奇应该像：

（红点）20％分位数（绿点）40％分位数（橙色点）80％分位数

Answer 1

使用人工（空）系列创建图例条目：

highchart() %>%

   # add the series and exclude it from the legend
   hc_add_series(data = tmp, type = "line", showInLegend = F) %>% 

   # add three empty series for the legend entries. Change color and marker symbol
   hc_add_series(data = data.frame(), name = "20% Quantile", color = "#FF0000", marker = list(symbol = "circle"), type = "scatter") %>% 
   hc_add_series(data = data.frame(), name = "40% Quantile", color = "#00FF00", marker = list(symbol = "circle"), type = "scatter") %>% 
   hc_add_series(data = data.frame(), name = "80% Quantile", color = "#ffa500", marker = list(symbol = "circle"), type = "scatter")
