HighCharts之圖表背景設定

 為HighCharts設定XAxis的PlotBands屬性，全部程式碼如下：

Highcharts chart = new Highcharts("HC" + divName)
               .InitChart(new Chart
               {
                   DefaultSeriesType = CT_type,
                   Width = _width,
                   Height = _height,
                   ClassName = _Title,
                   BackgroundColor = null
               }).SetCredits(new Credits { Enabled = false })
               .SetTitle(new Title
               {
                   Text = _Title
               })
               .SetXAxis(new XAxis
               {
                   Title = new XAxisTitle { Text = "單位:" + unitName },
                   Categories = xCategoryList.ToArray(),
                   Reversed = false,
                   Opposite = false,
                   PlotBands = new[]{

                                              }        }
