I am pulling in data for drwaing on a chart. My data formerly displayed
properly, but when the data set changed, it no longer displays properly. I can
see the data in a dataGrid so I know its there:

<mx:DataGrid dataProvider="{axis2.data}" width="400">
<mx:columns>
<mx:DataGridColumn dataField="point1" width="300" />
<mx:DataGridColumn dataField="point2" />
</mx:columns>
</mx:DataGrid>

axis2.data is an ArrayCollection
point1 is a Date
point2 is a Number

But with charts, the display gets flaky. I can get it to show up in an Line
chart, but not in a Plot chart. I'm wondering if it is failing to see the Date
object. But then why does it work in the Line chart? What in the data would
cause the entire chart to choke?
