在 x 轴上的一个点上显示所有值并更改 rCharts highcharts 的范围

Question

我刚刚进入 rCharts，我想增强我的图表。

• 我想更改图表中轴的最小值/最大值，

• 我还想在 x 轴上显示每个点的所有值 当我将鼠标悬停在它上面时。目前，我每 x 只能查看一个数据点 当我将鼠标悬停在轴上时

有人可以帮我展示一下它的语法吗？非常感谢。

library(rCharts)
h <- Highcharts$new()
h$xAxis(categories = c('Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
                       'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'))
h$yAxis(list(list(title = list(text = 'Rainfall'))
             , list(title = list(text = 'Temperature'), opposite = TRUE)
             , list(title = list(text = 'Sea Pressure'), opposite = TRUE))
)
h$series(name = 'Rainfall', type = 'column', color = '#4572A7',
         data = c(49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4))
h$series(name = 'Temperature', type = 'spline', color = '#89A54E',
         data = c(7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6),
         yAxis = 1)

h$series(name = 'Sea-Level Pressure', type = 'spline', color = '#AA4643',
         data = c(1016, 1016, 1015.9, 1015.5, 1012.3, 1009.5, 1009.6, 1010.2, 1013.1, 1016.9, 1018.2, 1016.7),
         yAxis = 2)
h

到目前为止，您尝试/搜索了什么？

• 来自http://api.highcharts.com/highcharts/xAxis.max（Y轴相同）

  h$yAxis(
     list(
       list(title = list(text = 'Rainfall'), min = 0),
       list(title = list(text  = 'Temperature'), max = 410, opposite = TRUE),
       list(title = list(text = 'Sea Pressure'), min = 1, max = 2, opposite = TRUE)
      )
   )

  h$tooltip(shared = TRUE)
