Google Charts – 组合图

Google Charts – 组合图


组合图有助于将每个系列呈现为以下列表中的不同标记类型:线、区域、条、烛台和阶梯区域。要为系列分配默认标记类型,请使用 seriesType 属性。系列属性用于单独指定每个系列的属性。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所以,让我们看看完整的例子。

配置

我们使用ComboChart类来显示基于组合的图表。

//combination chart
var chart = new google.visualization.ComboChart(document.getElementById('container'));
