本章节我们将为大家介绍 Highcharts 的气泡图。
我们在前面的章节已经了解了 Highcharts 配置语法。接下来让我们来看下 Highcharts 的其他配置。
配置 chart 的 type 为 'bubble' 。chart.type 描述了图表类型。默认值为 "line"。
chart.zoomType 属性可配置图表放大 ，通过拖动鼠标进行缩放，沿x轴或y轴进行缩放，可以设置为：'x','y','xy'。
var chart = {
type: 'bubble',
zoomType: 'xy'

以上实例输出结果为：
设置 series.marker 渐变让其看起来有 3D 的效果。
