The yField property, for example, on a ColumnSeries class is a String. The docs define yField as the "field of the data provider that determines the y-axis location of the top of a column". Most examples, show simple immediate child relations by node name, such as yField="Profit" for the data
<item> <Sales>250</Sales> <Profit>100</Profit> </item> <item> <Sales>450</Sales> <Profit>200</Profit> </item> I've also seen yField properties using the attribute (e4x) axis (e.g. yField="@profits" for <item profits="200"/>). However, I can't to get something like yField="trait (@field=='sales')[EMAIL PROTECTED]" to work for <item> <trait field="sales" value="450"/> <trait field="profit" value="200"/> </item> I'm assuming the field binding doesn't give me full access to the e4x syntax. Is there anything beyond child nodes by name and attribute nodes by name that I can specify? Is there some way I can override the ColumnSeries to use a custom lookup function to look up the value? Any help would be much appreciated. Justin Makeig
