以下是带符号的样条曲线图的示例。

我们已经在Highcharts Configuration Syntax一章中看到了用于绘制图表的配置。现在，我们将讨论带符号的样条图的示例。我们还将了解所采取的其他配置/步骤。

配置 (Configurations)

使用marker.symbol属性将符号添加到一系列图表中。它可以是预先配置的符号，如“square”，“diamond”或图像的url。标记也可以添加到系列数据的任何位置。

系列 (series)

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]
   }
];
