Sorting Persisted XML in Charts

[Avi]

Hi

Yet another question on the persisted XML data source approach for OWC:

If I bring in a data source (converted into the XML persistence format), the
data is read in correctly by the charting engine - except for 1 issue: the
engine will attempt to resort the data alphabetically. Is there a way of
specifying my own sort order, or at worst, specifying that it sort the data
in the order in which it was received?

This is a particular issue when reading in data, for example, by month:
April is the 4th row, but is placed first in the chart series or category
order.

Any suggestions?

thanks
Avi
