Google Charts - Combination Chart
组合图表有助于将每个序列呈现为以下列表中不同的标记类型:线、区域、条形、蜡烛图和阶梯区域。要为序列分配默认标记类型,请使用 seriesType 属性。序列属性将用来分别指定每个序列的属性。我们已经在 Google Charts Configuration Syntax 章节中看到了用于绘制此图表的配置。,让我们看一个完整的例子。
Configurations
我们已经使用 ComboChart 类来显示基于组合的图表。
//combination chart
var chart = new google.visualization.ComboChart(document.getElementById('container'));
