在 highcharter 散点图上标记点

Question

我想在高散点图中标记每个单独的点。下面的代码生成一张图表：

library(highcharter)
df = data.frame(name = c("tom", "dick", "harry"), 
           height = c(170L,180L, 185L), 
           weight = c(65L, 68L, 75L))

highchart() %>%
hc_add_series(df, type = "scatter", hcaes(x = weight, y = height), showInLegend = FALSE) %>%
hc_tooltip(pointFormat = "height: {point.y} <br> weight: {point.x}")

将鼠标悬停在每个点上显示："series 1, height: 170, weight: 65" 等。我希望标签在鼠标悬停在汤姆上方时显示 "tom, height: 170, weight: 65"，对于迪克和哈利也是如此。

谢谢

我刚刚在 hcaes

中添加了组变量

 highchart() %>%
  hc_add_series(df,type = "scatter", 
                hcaes(x = weight, y = height, group=name), showInLegend = FALSE) %>%
  hc_tooltip(pointFormat = "height: {point.y} <br> weight: {point.x}")

而且效果很好。

根据评论，我提出了另一种选择。

选项 1

将highchart()更改为hchart()

hchart(df,type = "scatter",
       hcaes(x = weight, y = height, group = name),
       showInLegend = FALSE) %>%
  hc_tooltip(pointFormat = "height: {point.y} <br> weight: {point.x}")

选项 2

使用 hc_add_series 中的 marker 选项。

highchart() %>%
  hc_add_series(df,type = "scatter", 
                hcaes(x = weight, y = height, group = name),
                showInLegend = FALSE, 
                marker = list(symbol = fa_icon("circle")),
                color = "blue") %>%
  hc_tooltip(pointFormat = "height: {point.y} <br> weight: {point.x}")
