到目前为止，我正在考虑在完全使用 Ext JS 构建的应用程序中使用 FusionCharts。但是，我不认为有特定的推荐实现或连接器可以轻松地将 FusionCharts 添加到 Ext JS 应用程序。网上有很多其他人在 Ext JS 应用程序中添加图表的例子：
最后一个讨论了一种为 FusionCharts 创建 Ext JS 类的方法，该类将一些图表功能“包装”在适当的类中：
/* * ?????? : var testdata = { part : { 'Jul 01' : 2000, 'Aug 02' : 2400, 'Sep 03' : 2000, 'Oct 04' :
* "", 'Dec 05' : null }, zoo : { 'Jul 01' : 4000, 'Aug 02' : 3400, // 'Sep 03' : 3000, // 'Oct 04' :
* 5200, 'Dec 05' : 4210 }, hotel : { // 'Jul 01' : 6000, 'Aug 02' : 6400, // 'Sep 03' : 7000, 'Oct
* 04' : 8200, 'Dec 05' : 8100 } }; // this.setChartData(testdata); ????????????
*/
