在工具提示 R Highcharts 中添加附加信息
Add Additional Information In Tooltip R Highcharts
我有一些数据想用 highcharts 绘制图表。当我将鼠标悬停在给定点上时,我希望工具提示也包括列 "type"。这是我当前的可重现示例。
library(highcharts)
dat = data.frame(first = rnorm(10), second = rnorm(10), type = rep(c("AAPL", "MSFT"),5))
highchart()%>%
hc_xAxis(categories = dat$Open_Date)%>%
hc_add_series(name = "first", data = dat$first, type = "column")%>%
hc_add_series(name = "second", data = dat$second, type = "line")
如果您在 hc_add_series
函数中将 dat
作为 data
传递,您可以访问 tooltip
参数中的其他列,例如 type
:
library(highcharter)
dat = data.frame(first = rnorm(10), second = rnorm(10), type = rep(c("AAPL", "MSFT"),5))
highchart()%>%
#hc_xAxis(categories = dat$Open_Date)%>%
hc_add_series(name = "first", data = dat, hcaes(y = first), type = "column",
tooltip = list(pointFormat = "{point.type}: {point.first}"))%>%
hc_add_series(name = "second", data = dat, hcaes(y = second), type = "line",
tooltip = list(pointFormat = "{point.type}: {point.second}"))
