Hi All
When i used ColumnChart component, i find if data is a big negative
number,mx.charts.LinearAxis's adjustMinMax method computed a error
computedInterval. How can i resolve the problem? Thanks.
Test case like this:

<?xml version="1.0"?>
<!-- charts/BasicColumn.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script><![CDATA[
import mx.collections.ArrayCollection;
import mx.charts.LinearAxis;
import mx.controls.Alert;
[Bindable]
public var expenses:ArrayCollection = new ArrayCollection([
{Month:"Jan", Profit:-16401640, Expenses:1500},
{Month:"Feb", Profit:-16401640, Expenses:1500}
]);
]]></mx:Script>
<mx:Panel title="Column Chart">
<mx:ColumnChart id="myChart" dataProvider="{expenses}"
showDataTips="true">
<mx:horizontalAxis>
<mx:CategoryAxis id="ca"
dataProvider="{expenses}"
categoryField="Month"
/>
</mx:horizontalAxis>
<mx:series>
<mx:ColumnSeries id="columnSeries" xField="Month"
yField="Profit" displayName="Profit" />
</mx:series>
</mx:ColumnChart>
<mx:Legend dataProvider="{myChart}"/>
</mx:Panel>
</mx:Application>
