Can you please change your xml to this format:

<?xml version="1.0" encoding="UTF-8"?>
<data>
    <set>
        <months>1/1/2008</months>
        <cash>50500</cash>
        <stocks>198192</stocks>

Now update the function xmlHandler() to this:

ERROR: 1120: Access of undefined property srv. line 7

I removed from line 7 and thew no errors but when I ran it - the data didnt show.

;srv.send();

Open in new window

deepanjandas

srv might be a HTTP Handler for fetching the xml data which is missing,

So add a HTTP handler with the id as srv, and the source path to that of the xml.

Also keep the srv.send in where it was and you should be done.

Try this way instead of the model:

<mx:HTTPService id="srv" resultFormat="e4x" result="xmlHandler(event)" />

tried changing "Additional Compiler Arguments:

to

-use-network=false

still same error.

deepanjandas

Add this:

<mx:HTTPService id="srv" resultFormat="e4x" result="xmlHandler(event)" fault="onFault(event)" useProxy="false"/>

private function onFault(event:FaultEvent):void{
    //on error
}

The process is correct, just check whether the chartInfo object is compatible as the ColumnChart dataprovider. I will try to check your code today and will update you.
