You might want to check out Flex Data
Services too, we have paging built right into the system J
However it’s worth noting that the
charts do not support paged data (where it comes down incrementally), in order
to draw successfully a chart assumes that all data is present.

Thanks alot Matt.
I had checked also
linerealtime.mxml which says "In a real life scenario, you could poll the
server here, or use an XMLSocket or Flash Communication Server approach to push
data from the server to the client." Can you elaborate more on
XMLsocket and how it works?
I will try out
HTTPService with e4x. But I think using paged remote data providers may
be a better technique for my case. This could provide better streaming-like
behavior.

E4X has an xpath like syntax
which may be better for you. Check out the
XMLListCollection as something you can assign into
a chart and the e4x
operators to build the right list. Make sure
resultFormat="e4x" on the
HTTPService, it might improve performance.

Subject: [flexcoders] Large XML data binding to
FLEX Chart
Hi all,
I am newbie trying to use FLEX to build chart apps
but I experience
huge problem when the data source in URL from
local hard drive is
around 6MB (request through mx:HTTPService).
Firefox 1.5, Windows XP with adobe FES had failed totally and the
memory/IO writes reached almost 1GB/50k before
firefox crashed.
Later I try with pre-compiled flash with tomcat
apache, the charts
work work sluggishly.
I would like to know is there any binding
mechanism that can stream
the XML data over through HTTP? Something
like active stream format
for movie/sound.
Is FLEX chart support JXPATH/XSLT? I w! ould
like to build a Flex chart
that allows user to enter XPATH/XSLT and produce
the chart dynamically.
Thanks for your patience in the reading.
Meanwhile I am finding the
answer myself reading the help documents provided.
