Not sure why my post isn't visible...So here is my problem again.
I am using the code from the "charting explorer" component that is
available at
http://flexapps.macromedia.com/flex15/chartexplorer/explorer.mxml?versionChecked=true"
The sample is column chart, styles examples #3.
Using a gradient causes my bars to become invisible, yet the data is
still present and the tool tip shows the plotting points on the chart.
If I comment out the <mx:fill> portion of each series the bars will
plot and become visible...but that means no style!
Here is the sample code if you don't want to view the link.
<mx:ColumnChart id="chart" dataProvider="{results}"
showDataTips="true" width="100%" height="100%" columnWidthRatio="0.9">
<mx:horizontalAxis>
<mx:CategoryAxis dataProvider="{results}"
categoryField="month"/>
</mx:horizontalAxis>
<mx:series>
