    Line series Array Collection


      Hi i am building a line chart.



      public var expenses:ArrayCollection = new ArrayCollection([
              {Month:"Jan", Profit:2000, Expenses:1500, Amount:450},
              {Month:"Feb", Profit:1000, Expenses:200, Amount:600},
              {Month:"Mar", Profit:1500, Expenses:500, Amount:300}



      In my case i do not know what will be the names (in this case Month , Profit )


      So how do i build me arraycollection without know the labels

          Is your problem is about how to populate the ArrayCollection or about assigning the datafields to the LineSeries...dynamically?

            How will you get the data for your chart? Is it going to be an xml? With this assumption, I am quoting an example with xml here.


            Suppose you get the following xml.


            var x:XML = new XML(<root>
                      <item meta="month">Jan</item>
                      <item meta="profit">2000</item>
                      <item meta="expenses">1500</item>
                      <item meta="amount">450</item>
                      <item meta="month">Feb</item>
                      <item meta="profit">1000</item>
                      <item meta="expenses">200</item>
                      <item meta="amount">600</item>


            Now you need to convert this to ArrayCollection.


            public var expenses:ArrayCollection = new ArrayCollection();
            for each(var items:XML in x.children()){
                 var obj:Object = new Object();
                 for each(var item:XML in items.children()){
                      obj[item.meta] = item.text();
