使用基于json的配置在amCharts中创建标签

<div id="chartdiv"></div>

// 创建一个包含标签配置的JSON对象
var chartConfig = {
  "type": "serial",
  "dataProvider": [{
    "country": "USA",
    "visits": 4025
  }, {
    "country": "China",
    "visits": 1882
  }, {
    "country": "Japan",
    "visits": 1809
  }],
  "categoryField": "country",
  "graphs": [{
    "valueField": "visits",
    "type": "column"
  }],
  "chartCursor": {},
  "categoryAxis": {
    "gridPosition": "start"
  },
  "valueAxes": [{
    "title": "Visits"
  }],
  "balloon": {},
  "titles": [{
    "text": "Visits by Country"
  }]
};

// 使用amCharts的makeChart方法创建图表
var chart = AmCharts.makeChart("chartdiv", chartConfig);
