yep. that's it - incorrect namespace. but I've hit another problem...
performance on drawing it, esp compared to the origional version.
*really* noticable. I must be asking a lot from the framework to do
this, unless I'm not doing it the _best_ way?
<BarChart id="chart" width="100%" height="100%"
dataProvider="{dataSet.Sample}">
<series>
<BarSet type="stacked">
<BarSeries xField="costs"
itemRenderer="examples.customizing.LabeledRenderer2" />
<BarSeries xField="overhead"
itemRenderer="examples.customizing.LabeledRenderer2" />
<BarSeries xField="oneTime"
itemRenderer="examples.customizing.LabeledRenderer2" />
</BarSet>
</series>
<verticalAxis>
<CategoryAxis categoryField="month" />
</verticalAxis>
</BarChart>
