I can't see what I forgot...

I set up a dummy adapter that serves the same item (Next) with the same fields (Next and timestamp) as yours.

Then I use its data with this front-end html page and it works correctly (the PushPage/engine configuration is done in the external misc.js file; as you did note my PushPage object is called pushPage while yours is lsPage).

Note also that the positionXAxis and positionYAxis calls are made with static values; this is usually not appropriate and you have to find a way to configure them correctly accordingly with the data you're receiving (that's why in our ChartDemo we wait for the fist update before configuring them).

Please be sure also to check the jsDocs for the ChartTable and ChartLine classes

Try to take a look at it:

it finally works. I get the required graph. And it closely resembles sent values. I thank you for your help.

I'll go play with Flex to see if I can create a little more dynamic graph and everything but essentially I'm done. Mission acomplished.

ps. Can I get source code from that Flash stocklist demo just so I could see what it looks like? it may be of help in making flash application.

Cyro,

You can find the source code of the Flash demo inside your Lightstreamer distribution in the "DOCS-SDKs/sdk_client_flash_flex(js_bridge)/examples/FlashStockList" folder.
