要在flash动画中加载两个或多个 FusionCharts 图表文件，只需为每个图表类创建一个实例，提供相应的XML数据然后将它呈现出来就可以了，非常简单。

在本例中，我们在FlashExamples文件夹下创建MultipleCharts.fla，然后再在这个新创建的文件夹下创建一层 "Graphic Elements"，添加两个圆角矩形的背景框，用来加载两个图表，如图所示：

示例代码：

//You first need to include the following two files in your movie.
//These two files contain pre-loading functions and application
//messages for the chart.
//Note: If you're loading multiple charts in your Flash movie, you
//do NOT need to include these files for each chart. You can put these
//lines in the main timeline, so that it gets loaded only once.
#include "com/fusioncharts/includes/LoadingFunctions.as"
#include "com/fusioncharts/includes/AppMessages.as"

//To create the chart, you now need to import the Class of the 
//chart which you want to create. All charts are present in the package 
//com.fusioncharts.core.charts (Download Package > SourceCode folder)
//If you're using multiple charts, you can import all the requisite
//chart classes in the main timeline of your movie. That way, you
//will not have to import the chart classes everytime you wish to use.
import com.fusioncharts.core.charts.Column2DChart;
import com.fusioncharts.core.charts.Line2DChart;

// ------------- XML Data for the charts -------------- //
//Data for chart 1
var strXML1:String = "<chart showBorder='0' bgAlpha='0,0' palette='1' caption='Hourly Working Rate' numberPrefix='$'>";
//Add simple data for demo.
strXML1 = strXML1+"<set label='John' value='32' />";
strXML1 = strXML1+"<set label='Mary' value='65' />";
strXML1 = strXML1+"<set label='Michelle' value='29' />";
strXML1 = strXML1+"<set label='Cary' value='43' />";
strXML1 = strXML1+"</chart>";
var xmlData1:XML = new XML(strXML1);

// Data for Chart 2
var strXML2:String = "<chart showBorder='0' bgAlpha='0,0' palette='1' caption='Hours Worked Last week' canvasPadding='20'>";
//Add simple data for demo.
strXML2 = strXML2+"<set label='John' value='49' />";
strXML2 = strXML2+"<set label='Mary' value='34' />";
strXML2 = strXML2+"<set label='Michelle' value='61' />";
strXML2 = strXML2+"<set label='Cary' value='40' />";
strXML2 = strXML2+"</chart>";
var xmlData2:XML = new XML(strXML2);
// --------------------------------------------------- // 

// -------------- Actual Code to create the chart ------------//
//Create movie clips required for both the charts
var chartContainer1MC:MovieClip = this.createEmptyMovieClip("ChartHolder1", 1);
var chartContainer2MC:MovieClip = this.createEmptyMovieClip("ChartHolder2", 2);

//Now, instantiate the charts using Constructor function of the chart.
var chart1:Column2DChart = new Column2DChart(chartContainer1MC, 1, 380, 325, 20, 15, false, "EN", "noScale");
var chart2:Line2DChart = new Line2DChart(chartContainer2MC, 1, 380, 325, 440, 15, false, "EN", "noScale");

//Convey the XML data to chart. 
chart1.setXMLData(xmlData1);
chart2.setXMLData(xmlData2);

//Draw the charts
chart1.render();
chart2.render();
//Stop
stop();

解释一下上面的代码：

1、首先加进了com/fusioncharts/includes/LoadingFunctions.as & com/fusioncharts/includes/AppMessages.as ，预加载图表所需的文件；
2、然后，我们要绘制两个图表，所以导入Column2DChart 类和Line2DChart 类；
3、为两个图表创建XML数据（在此例中，是硬编码的XML数据），你也可以根据数据源动态创建XML数据；
4、将XML数据转换为XML对象；
5、然后为两个图表分别创建两个空的动画片段；
6、为两个图表创建实例以及所需的参数。设置x和y轴平移线以便在柱状图右边绘制；
7、用setXMLData 传递XML数据；
8、最后，向每个图表的实例对象调用 render() 方法，绘制两个图表。

查看应用程序，输出效果如下图：

在本例中，我们只加载了2D柱状图和线形图，你也可以加载FusionCharts的其他图表类型。另外，你还可以加载任意数量的图表到你的应用程序中。
