Good luck with your project.

I think I've traced my major stumbling block to the fact that startElement() only gets called for the first <Value> even though endElement() gets called for each one.

If someone could tell me why this is the case then I think I'll be there.

TimeSeries (order of items)

Hi,
are the items kept in chronological order?
If not, is there any way to sort them after they've been added?

I'd like to be able to copy the 0th to 6th items (chronologically) from one TimeSeries to another and don't want to have to search by date.

All suggestions welcome, j

Hi, thanks for the encouragement. I was expecting that there could be missing values (e.g. today's includes values for series 1&2, and tomorrow's item has values for series 2&3), so that might allow the scenario you suggest. I've not seen a java class for properly handling string dates, which ought ...

I'm not sure if you can have the axes on top, but you should be able to use semi-transparent surface fills. (look into setting the Alpha)

:?:

It seems I actually misunderstood what was happening with the Values - in fact it simply uses the first Value and skips the rest. I can't see what needs to be changed to force it to process them all (I want to be able to pass it a comparable to select which Value to insert.) If anyone can help me wi...

Success!

I have now successfully re-written code which accepts XML in the following format and places it in a TimeSeriesCollection. <?xml version="1.0" encoding="utf-8"?> <TimeSeriesCollection> <Series> <Item> <Key>2004-12-01</Key> <Value Series="1">8.48</Value> <Value Series="2">8.55</Value> <Value Series="...

I guess my XML ought to be in the following format: <?xml version="1.0" encoding="utf-8"?> <dataset> <Series name="Series 1"> <Item> <Key>2004-12-01</Key> <Value>8.48</Value> </Item> ... </Series> ... </dataset> to save on some code re-writing. However, it would be great if I could instead use somet...

that's a good point.
I already have to transform (xslt) the xml I'm using, so at the same time changed the dates to ISO 8601 (e.g. 2005-07-13).

I'm not entirely sure where to start still, so any pointers would be much appreciated.

Import XML into TimeSeries?

Hi, I need to import XML data to a TimeSeries, but see that this has not yet been implemented officially. If anyone has any suggestions for methods on doing so, or even has actually done so, and would be willing to share it would be much appreciated, by myself and many others. Specific questions inc...
