Ah, this is actually the result of a change that was made to the C&G
API. If you want labels over a particular set of columns, you have
to specify a labeldatapath on that datacolumn. (Sorry, this wasn't a
very well-publicized change, and the C&G documentation was/is...
rather lacking.) So, if you change the dataseries in
test_column_01.lzx to the following:
<dataseries datapath="baseball:/records" >
<datacolumn name="x" columndatapath="record/@year"
datatype="number"/>
<datacolumn name="label" columndatapath="record/@year"/>
<dataseries label="wins">
<datacolumn name="y" columndatapath="record/@wins"
labeldatapath="record/@wins"
datatype="number"/>
<datacolumn name="tooltip" columndatapath="record">
<method name="processData" args="v">
return "year: " + v.attributes.year + "
wins: " + v.attributes.wins;
</method>
</datacolumn>
</dataseries>
</dataseries>
It should work. Sorry about that... perhaps maybe file a bug against
better documenting the labeldatapath attribute?

Column labels were displayed as 'undefined' if no data were
available to display . Note. I found a new regression that the
labels and axis information is no longer displayed. I'll create a
new jira task to cover this.
