我有一个带有自定义dataTipRenderer的flex AreaChart:
<mx:AreaChart id="numParticipants"
dataProvider="{UsersModel.graphData.data_points.point}"
seriesFilters="[]" right="10" left="10"
top="10" bottom="10" fontSize="9" color="#8D8D8D"
dataTipRenderer="tooltip.ChartTooltip"
showDataTips="true" dataTipMode="multiple" mouseSensitivity="10">
渲染器代码在这里:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" top="5" width="154" height="42">
<mx:Style source="css/style.css"/>
<mx:Script>
<![CDATA[
import models.UsersModel;
import mx.charts.HitData;
import mx.formatters.DateFormatter;
override public function set data(value:Object):void
{
//trace("ChartTooltip: x=" + x + " y=" + y);
var dataPoint:HitData = value as HitData;
var date:Date = new Date();
var units:String = UsersModel.graphData.units;
date.setTime(dataPoint.item.timestamp * 1000);
switch (units)
{
case "days":
txtDate.text = dayFormatter.format(date);
break;
case "hours":
txtDate.text = hourFormatter.format(date);
break;
}
txtUsers.text = dataPoint.item.participants;
}
]]>
</mx:Script>
<mx:DateFormatter id="hourFormatter" formatString="L:NN A"/>
<mx:DateFormatter id="dayFormatter" formatString="MMM DD"/>
<mx:Image source="@Embed('images/BaloonLeft.png')" x="0" width="25" height="42" y="0" maintainAspectRatio="false" />
<mx:Image source="@Embed('images/BaloonCenter.png')" x="25" width="120" height="42" y="0" maintainAspectRatio="false"/>
<mx:Image source="@Embed('images/BaloonRight.png')" x="145" width="9" height="42" y="0" maintainAspectRatio="false" />
<mx:VBox x="25" width="120" height="42" y="0" verticalScrollPolicy="off" horizontalScrollPolicy="off" verticalGap="0">
<mx:HBox>
<mx:Label text="Date:" styleName="dataTooltipText" fontWeight="bold"/>
<mx:Label id="txtDate" styleName="dataTooltipText"/>
</mx:HBox>
<mx:HBox>
<mx:Label text="Users:" styleName="dataTooltipText" fontWeight="bold"/>
<mx:Label id="txtUsers" styleName="dataTooltipText"/>
</mx:HBox>
</mx:VBox>
工具提示正确显示某些数据点,但对于其他数据点,它看起来不太好。

任何想法为什么?
非常感谢!

我建议将图片和内容放在自定义layoutContainer中,例如HBox:
<mx:HBox>
<mx:Image source="@Embed('images/BaloonLeft.png')" x="0" width="25" height="42" y="0" maintainAspectRatio="false" />
<mx:Canvas>
<mx:Image source="@Embed('images/BaloonCenter.png')" x="25" width="120" height="42" y="0" maintainAspectRatio="false"/>
<mx:VBox x="25" width="120" height="42" y="0" verticalScrollPolicy="off" horizontalScrollPolicy="off" verticalGap="0">
<mx:HBox>
<mx:Label text="Date:" styleName="dataTooltipText" fontWeight="bold"/>
<mx:Label id="txtDate" styleName="dataTooltipText"/>
</mx:HBox>
<mx:HBox>
<mx:Label text="Users:" styleName="dataTooltipText" fontWeight="bold"/>
<mx:Label id="txtUsers" styleName="dataTooltipText"/>
</mx:HBox>
</mx:VBox>
</mx:Canvas>
<mx:Image source="@Embed('images/BaloonRight.png')" x="145" width="9" height="42" y="0" maintainAspectRatio="false" />
</mx:HBox>
我还没有真正测试过这个,但我想给你一个主要的想法。 HBox水平布局所有内容,我介绍的Canvas可以将背景和内容相互绘制。正如我所提到的......我希望它能给你一般的想法。
