我有以下 HTML 代码。这是工作。

<html>
  <head>     
    <title>My First chart using FusionCharts - Using pure JavaScript</title>    

    <script type="text/javascript" src="http://www.fusioncharts.com/lib/jquery/jquery-1.6.2.min.js"></script>
    <script language="JavaScript" src="http://www.fusioncharts.com/lib/js/FusionCharts.js"></script>
    <script language="JavaScript" src="http://www.fusioncharts.com/lib/js/FusionCharts.HC.js"></script>
    <script language="JavaScript" src="http://www.fusioncharts.com/lib/js/FusionCharts.HC.Charts.js"></script>
    <script language="JavaScript" src="http://www.fusioncharts.com/lib/js/jquery.min.js"></script>

  </head>
  <body>     
    <div id="chartContainer">FusionCharts will load here!</div>          
    <script type="text/javascript">

    //FusionCharts.setCurrentRenderer('javascript');
           var chartObj = new FusionCharts({
           swfUrl: "http://www.fusioncharts.com/demos/gallery/Charts/Column2D.swf",
           width: "500", 
           height: "300",
           id: 'sampleChart',
           dataSource: "http://www.fusioncharts.com/demos/gallery/Data/Col2D1.xml",
           dataFormat: FusionChartsDataFormats.XMLURL,           
           renderAt: 'chartContainer'
        }).render();

    </script>        
  </body> 
</html>

当我使用setCurrentRendererjavascripde 模式时。它给了我“没有数据显示”。

从 FusionCharts 网站以 JavaScript 加载数据会导致跨域错误。它是浏览器本身内置的安全性。

XMLHttpRequest cannot load http://www.fusioncharts.com/demos/gallery/Data/Col2D1.xml. Origin http://localhost is not allowed by Access-Control-Allow-Origin.

尝试在您自己的本地服务器上托管 JavaScript 文件、Flash 文件和 XML 数据，它应该可以完美运行。

跨域问题可以通过实现CORS——跨源资源共享来解决。确保提供数据的服务器在响应中发送一些额外的 http-headers：

Access-Control-Allow-Origin: http://the_url_that_hosts_the_page

Access-Control-Allow-Headers: If-Modified-Since

我在下面的例子中使用了 javascript 渲染：

        FusionCharts.setCurrentRenderer("javascript");
       var chart = new FusionCharts("MSBar3D.swf", "ChartId", "560", "400", "0", "0");
       chart.setXMLData( dataString );         
       chart.render("chartdiv");
    </script>

      <p align="center">3D Bar chart showing sales comparison of 5 countries across 3 years. Click on a legend item to show/hide the data series.</p>


它适用于java脚本渲染..我希望这个例子有帮助
