[flexcoders] Programatically creating LineSeries

[Mehul Doshi]

Hi,

I have a few questions on how I should go about achieving something 
using Flex Charting.

I have a Java servlet/controller that will return XML data. The data 
will consist of multiple datapoints for multiple companies. Let's 
assume that the xml follows the below structure:

<company1 name="ABC">
   <datapoint date="Jan">50</datapoint>
   <datapoint date="Feb">70</datapoint>
</company1>
<company2 name="DEF">
   <datapoint date="Jan">70</datapoint>
   <datapoint date="Feb">50</datapoint>
</company2>

Using this XML, I need to programatically (using 
Javascript/Actionscript) create a chart with multiple LineSeries and 
set the dataprovider for each. 

My questions are:

1. How do I obtain the XML data? I'm currently using XMLHttpRequest 
to get it...any better approach? Do I need to use the DataServices 
feature of Flex?
2. Using my current approach, I'm not sure how I can set the 
dataprovider (and xfield,yfield) for each LineSeries (each company)?

Thanks,
Mehul.
