Adobe FLEX 2-MIGRATING APPLICATIONS TO FLEX 2 Manual page 166

Skins
Skins are now called renderers. For example, the CandlestickSkin class is now
CandlestickRenderer.
Renderers
Some functionality for the AxisRenderer was moved to other axis objects.
The

axis type (such as CategoryAxis). The signature for the function is changed as well. Instead of
a single parameter,
the labelFunction()
is as follows:
labelFunction(categoryValue:Object, previousCategoryValue:Object,
axis:axis_type, categoryItem:Object);

example, in Flex 1.x you defined both the horizontalAxis and the horizontalAxisRenderer, as
the following example shows:
<mx:horizontalAxis>
<mx:CategoryAxis dataProvider="{expenses}" categoryField="Month"/>
</mx:horizontalAxis>
<mx:horizontalAxisRenderer>
<mx:AxisRenderer title="Expenses" labelFunction="defineLabel"/>
</mx:horizontalAxisRenderer>
In Flex 2, you set the
<mx:horizontalAxis>
<mx:CategoryAxis dataProvider="{expenses}" categoryField="Month"
title="Expenses" labelFunction="defineLabel"/>
</mx:horizontalAxis>
You no longer use renderers to change the appearance of ChartItems. In Flex 1.x, for example,
you could specify a CrossRenderer or TriangleRenderer to draw a ChartItem as a cross or a
triangle:
<mx:PlotSeries>
<mx:renderer>
<mx:CrossRenderer/>
</mx:renderer>
</mx:PlotSeries>
