我想在 Highcharter 中创建一个这样的图表以在 R 中使用。
理想情况下,我想做的是一个条形图,其中条形的宽度是事件发生天数的分布。我尝试过使用“pointWidth”,但是,我需要根据事件的长度来改变条形宽度。
这是我要绘制的数据框:
df <- data.frame(event = c("wedding", "party", "concert"),
start_date = as.Date(c("2017-10-01", "2017-11-01", "2017-11-20")),
end_date = as.Date(c("2017-10-10", "2017-11-18","2017-12-01")),
event_days = c(9,17,11),
customers = c("400", "150", "3000"))
以下是我通常在 ggplot 中的操作方式:
ggplot(df, aes(start_date, customers, width = event_days)) + geom_bar(stat = "identity")
我正在尝试做的是从技术上使条形的宽度超过事件发生的日子。
