1、问题背景

在Flex中，制作一个折线图。而且给折线图的横轴和纵轴进行样式设置，详细实现过程例如以下：

2、实现实例

（1）设置横轴样式和数据绑定

<mx:horizontalAxis>

	<mx:CategoryAxis categoryField="quarter" displayName="季度"/>

</mx:horizontalAxis>

<mx:horizontalAxisRenderers>

	<mx:AxisRenderer placement="bottom" tickLength="1" tickStroke="{new Stroke(0xFF0000,1)}"

								 axisStroke="{new Stroke(0xFF0000,1)}">

		<mx:axis>

		    <mx:LinearAxis id="bottomAxis"/>

		</mx:axis>

	</mx:AxisRenderer>

</mx:horizontalAxisRenderers>

（2）设置纵轴样式和数据绑定

<mx:verticalAxisRenderers>

	<mx:AxisRenderer placement="left" tickLength="1" tickStroke="{new Stroke(0xFF0000,1)}"

								 axisStroke="{new Stroke(0xFF0000,1)}">

	      <mx:axis>

		   <mx:LinearAxis id="leftAxis"/>

	      </mx:axis>

	</mx:AxisRenderer>

</mx:verticalAxisRenderers>

（3）在图上绑定横轴和纵轴

<mx:series>

	<mx:LineSeries verticalAxis="{leftAxis}" displayName="兔子" xField="quarter" yField="rabbit"/>

</mx:series>

3、实现结果
