rcharts highcharts plotLines [英] rcharts highcharts plotLines

问题描述

在绘图上使用rcharts（highcharts）绘制水平线时有点麻烦。我想用highcharts库中的plotLines来做到这一点。下面是我的代码：

I am having a little trouble to draw a horizontal line by using rcharts (highcharts) on a plot. I would like to use the plotLines from highcharts library to do this. Below is my code:

a$yAxis(title='my_Yaxis name', plotLines=list(color='red', value=10, width=2))   

没有plotLines，我的图表显示没有问题。一旦我加入plotline，它不起作用。我不确定rcharts是否支持高线图中的plotline？

Without the plotLines, my chart display with no problem. Once i added in the plotLines, it is not working. I am not sure if rcharts support plotLines in highcharts?

感谢这里的专家是否能给出建议。谢谢！

Appreciate if any experts here can give advice. Thanks!

推荐答案

你好，看看这个例子：

Hello look at this example :

library("rCharts")
# Some data
x <- abs(rnorm(10))
# A graph with column
h <- Highcharts$new()
h$chart(type = "column")
h$series(data = x)
h$xAxis(categories = letters[1:10])
# the horizontal line
h$yAxis(title = list(text = "rnorm()"),
        plotLines = list(list(
          value = mean(x),
          color = '#ff0000',
          width = 3,
          zIndex = 4,
          label = list(text = "mean",
                       style = list( color = '#ff0000', fontWeight = 'bold' )
          ))))
h

缺少a list（）在 plotLines 参数中，它需要两个 list 。

It's missing a list() in your plotLines argument, it needs two list.
