堆叠区域图，各个区域叠加

Highcharts 堆叠区域图

以下实例演示了堆叠区域图。

我们在前面的章节已经了解了 Highcharts 基本配置语法。接下来让我们来看下其他的配置。在 plotOptions 中添加 stacking 属性：

配置

plotOptions：数据点选项

plotOptions用于设置图表中的数据点相关属性。plotOptions根据各种图表类型，其属性设置略微有些差异。

配置图表堆叠设置 plotOptions.area.stacking 为 "normal"。如果禁用堆叠使用 null。如果值为 "percent" 堆叠则按百分比。

var plotOptions = {
   area: {
      stacking: ‘normal‘,
      lineColor: ‘#666666‘,
      lineWidth: 1,
      marker: {
         lineWidth: 1,
         lineColor: ‘#666666‘
      }
   }
};
