I have some data that I would like to graph using highcharts. When I hover over a given point, I would like the tooltip to also include the column "type". Here is my current reproducible example.
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$second, type = "line")
If you pass in dat
as data
in your hc_add_series
function, you can access other columns in the tooltip
argument, like type
:
library(highcharter)
dat = data.frame(first = rnorm(10), second = rnorm(10), type = rep(c("AAPL", "MSFT"),5))
highchart()%>%
#hc_xAxis(categories = dat$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}"))
