了解下何为 Highcharts 气泡图

本章节我们将为大家介绍 Highcharts 的气泡图。

配置

chart 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：

3D 气泡图

series.marker

设置 series.marker 渐变让其看起来有 3D 的效果。

marker: {
   fillColor: {radialGradient: { cx: 0.4, cy: 0.3, r: 0.7},
      stops: [[0, 'rgba(255,255,255,0.5)'],
         [1, Highcharts.Color(Highcharts.getOptions().colors[0]).setOpacity(0.5).get('rgba')]
      ]
   }
}
