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

下面给出了具有null和0值的3D柱形图的示例。

配置 (Configurations)

现在让我们看一下所采取的其他配置/步骤。

chart.options3d

将图表类型配置为基于3D。将类型设置为“列”。用于在3个维度中呈现图表的选项。

var chart = {
   type: 'column',
   options3d: {
      enabled: true,
      alpha: 15,
      beta: 15,
      depth: 50,
      viewDistance: 25
   }
};
