Good morning in PDT, and thanks for being here.
Me: new to AS & Flex, building a Linux-based dashboard, using
Flexbuilder alpha for Linux in Eclipse
( this does not have all features compared to Windows and OSX I believe,
and may be buggy)
*Problem:* I've been given an XML schema for incoming data thats
complex, and well, may not be optimum. :)
When I follow the tutorials using simple data,
<data>
<item>
<eth>eth0</eth>
<packets>1234</packets>
<bps>3005</bps>
</item>
<item>
<eth>eth1</eth>
<packets>517</packets>
<bps>4335</bps>
</item>
...
</data>
I am able to get a dynamic bar chart that responds to changes in number
of members of the "data" array of elements. But my real data is complex
( see below) and it appears to me that the dataFunc to chart series
dataprovider connection, which understands simple arrays, gets confused
with complex arrays.
*What I get thats wrong:*
Trace shows me getting results like
"<peas> data1 </peas>
<peas> data2 </peas>"
or using a different notation,
"data1data2"
when I expect an array of data1,data2
and the chart won't work at all.
*What I want to know:* I want some guidance to help me avoid dead ends-
Is my XML just flat not suitable?
Am I wrong about the problem?
Do I need to do some complicated restructuring of the data before I
return it from the dataFunc, so I send a simple array like shown above?
Thanks!
John
