Highcharts 曲线图以下实例演示了 带标记曲线图。
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如何配置。
配置
我们使用 marker.symbol 属性来配置标记。标记可以是 'square', 'diamond' 或 图片 url。标记可以添加在任何的数据点上：
var series= [{ name: 'Tokyo', marker: { symbol: 'square' }, data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, { y: 26.5, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' } }, 23.3, 18.3, 13.9, 9.6] }, { name: 'London', marker: { symbol: 'diamond' }, data: [{ y: 3.9, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/snow.png)' } }, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8] }]; 实例
