上一节提到open-flash-chart2的数据是通过存储在txt文件中，然后通过类似那个http://yoururl/chart.html?ofc=datafile.txt 这样的形式来加载不同的数据，当然ofc后面的参数可以是php文件，php类库的使用将在以后的教程中出现，本节将讨论使用js加载数据的另一种方法，代码如下：
是<script type="text/javascript" src="js/json/json2.js"></script>
<script type="text/javascript" src="js/swfobject.js"></script>
<script type="text/javascript">
swfobject.embedSWF("open-flash-chart.swf", "my_chart", "350", "200", "9.0.0");
</script>

<script type="text/javascript">

function ofc_ready()
{
 alert('ofc_ready');
}

function open_flash_chart_data()
{
 alert( 'reading data' );
 return JSON.stringify(data);
}

function findSWF(movieName) {
  if (navigator.appName.indexOf("Microsoft")!= -1) {
    return window[movieName];
  } else {
    return document[movieName];
  }
}
 
var data = {
  "elements": [
    {
      "type": "bar",
      "text": "u5317u4eac",
      "values": [
        9.9355,

        11.9911,
        10.2637,
        4.152,
        5.8293,
        17.8541,
        17.1762,
        25.2105,
        24.9323,
        23.5468,
        2.7642,
        3.9232,
        30.6192,
        17.9746,
        26.1273,
        14.5226,
        17.3219,
        5.0837,
        2.1281,
        18.9674,
        8.3799
      ]
    }
  ],
  "title": {

        "17",
        "18",
        "19",

        "22",
        "23"
      ]
    }
  },
  "y_legend": {

演示

这种方式更适合数据实时加载，比如php中带查询表单，open-flash-chart2的用法很灵活，如果你是新手可能现在还是一头雾水，上面的json的格式各个参数将在下一节里做详细的解释。
