3. 双轴，线和柱(Dual Axes, Line and Column)

双轴，线和柱(Dual Axes, Line and Column)

以下是具有Dual Axes，Line和Column的图表示例。

我们已经在Highcharts Configuration Syntax一章中看到了用于绘制图表的配置 。

下面给出具有双轴，线和柱的组合图的示例。

配置 (Configurations)

现在让我们看一下所采取的其他配置/步骤。

YAxis

使用chart.getYAxis（index）方法获取多个yAxis。

chart.getYAxis(0);  
chart.getYAxis(1);
