1、区域型图表AreaChart

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
	
	<mx:Script>
		<![CDATA[
		import mx.collections.ArrayCollection;
		
		[Bindable]
		// 绑定数据集
		public var expenses:ArrayCollection = new ArrayCollection(
				[
					{Month:"一月", Profit:2000, Expenses:1500, Amount:450},
					{Month:"二月", Profit:1000, Expenses:200, Amount:600},
					{Month:"三月", Profit:1500, Expenses:500, Amount:300}
				]
			);
		]]>
	</mx:Script>
	
	<!-- 创建面板容器 -->
	<mx:Panel title="图表控件的使用">
		<!-- 创建AreaChart图表 -->
		<mx:AreaChart id="myChart" dataProvider="{expenses}" showDataTips="true">
			<mx:horizontalAxis>
				<mx:CategoryAxis dataProvider="{expenses}" categoryField="Month" />
			</mx:horizontalAxis>
			<mx:series>
				<mx:AreaSeries yField="Profit" displayName="利润" />
			</mx:series>
		</mx:AreaChart>
		<mx:Legend dataProvider="{myChart}"/>
	</mx:Panel>
	
</mx:Application>

AreaChart 使用外部数据源

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
	<!-- 创建XML格式数据模型 -->
	<mx:Model id="expenses" source="assets/data.xml" />
	<mx:Panel title="Area Chart">
		<!-- 创建 AreaChart 图表 -->
		<mx:AreaChart id="myChart" dataProvider="{expenses.result}"
			showDataTips="true">
			<mx:horizontalAxis>
				<mx:CategoryAxis 
					dataProvider="{expenses.result}"
					categoryField="Month"
				/>
			</mx:horizontalAxis>
			<mx:series>
				<mx:AreaSeries
					yField="Profit"
					displayName="月份"
				/>
			</mx:series>
		</mx:AreaChart>
		<mx:Legend dataProvider="{myChart}"/>
	</mx:Panel>
</mx:Application>

assets/data.xml的内容如下

<data>
	<result>
