删除 highcharter R 中的网格线

Remove grid lines in highcharter R

我已经从 highcharter R 包创建了自己的绘图主题。我想删除背景中的白色水平线。我曾尝试将“gridLineWidth”设置为 0,但没有成功。这是我当前图表的图片。任何帮助将不胜感激。

my_theme = hc_theme(
  colors = c(
    "#5daa45","#0066b2","#d51f3a",   "#983794", "#ebe71c", "#5196bc"),
  chart = list(
    backgroundColor = "#242932",
    gridLineWidth = 0
  ),
  title = list(
    style = list(
      color = "#e8e8e8"
   #   fontFamily = "Lato"
    )
  ),
  subtitle = list(
    style = list(
      color = "#e8e8e8"
    #  fontFamily = "Shadows Into Light"
    )
  ),
  legend = list(
    itemStyle = list(
  #    fontFamily = "Tangerine",
      color = "#e8e8e8"
    ),
    itemHoverStyle = list(
      color = "#e8e8e8"
    )
  )
)

没有API *chart*.gridLineWidth 属性: https://api.highcharts.com/highcharts/chart.gridLineWidth

但是,*yAxis*.gridLineWidth*xAxis*.gridLineWidth 有一个:https://api.highcharts.com/highcharts/yAxis.gridLineWidth and https://api.highcharts.com/highcharts/xAxis.gridLineWidth :)
