我们已经在Highcharts Configuration Syntax一章中看到了用于绘制图表的配置。以下是百分比面积图的示例。

让我们在这里了解其他配置。我们在plotoptions中添加了stacking属性。

plotOptions

plotOptions是每个系列类型的配置对象的包装器对象。还可以为系列数组中给出的每个系列项覆盖每个系列的配置对象。这是为了将每个系列的值叠加在一起。

使用plotOptions.area.stacking将图表plotOptions.area.stacking为“百分比”。可能的值为null，禁用堆叠，“正常”堆栈按值，“百分比”按百分比堆叠图表。

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