Recently I had to increase the JAVA heap size to 256MB above during testing as flex with eclipse crashed so many times that I almost give up FLEX, the XML size should smaller than 300kb for each data binding. Otherwise Flashplayer will crashed with the browser when memory hit over few hundred MB.

Yes, Matt. I agree with you. With events it shouldn't be any problem to simulate the pagination. Infact I wrote a demo like that and it works fine for me.
I am started to look seriously to Flex just three days ago. I am very much impressed by the the extensible nature of each component. I was skeptical about extending the charting framework to add new charts and Ely told me that its possible. Moreover the syntax is so similar to Java, I didn't spent more than few mins to understand how to write new functions!
I can now say, you kept the name of product which suits to its natue... its really FLEXible.
Only matter is, we need to play around and make our hands dirty to understand the exact behaviour. I am waiting for production release of this product so that API docs, Samples will be available for me. I must congratulate you on a job well done.

You can simulate paging with a chart by gradually filling in the data (and adding length as it arrives), but a chart with no values may look very different than a chart that is filled in, and that is usually unacceptable.We do have a progress bar, and there are other ways of hooking up most of what you're asking for, you'll just need to see more of what we provide and play around.Matt

Subject: RE: [flexcoders] Large XML data binding to FLEX ChartThanks Matt. I suggest charts to support paging will be good. In future as network speed increase and we are able to process large data available at the client side.
I think it will be more user friendly to include progress bar, user interrupt function to halt/cancel data binding, display size of data available etc. Or i had miss from documents, all these are already available? I will check the documents again.
Matt Chotin <[EMAIL PROTECTED]> wrote:You might want to check ! out Flex Data Services too, we have paging built right into the system JHowever itâs 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.Matt

Subject: RE: [flexcoders] Large XML data binding to FLEX ChartThanks alot Matt.
I had checked also linerealtime.mxml w! hich 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.
Matt Chotin <[EMAIL PROTECTED]> wrote: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.
