[flexcoders] Charts and fields

Tue, 12 Apr 2005 23:22:39 -0700

Hi,

I ran into problem with charts. I have an object that contains another object and I need to make a chart using them. Let’s say that the object looks like this:

 

class com.mycom.myObjectX

            {

            public var myString:String;

            public var myOtherObject:SomeObject; // Contains a field: myNumber:Number

            }

 

 

I would like to do something like this with an array (myArray ) containing myObjectX’s:

 

<mx:ColumnChart id="bar" marginLeft="5" height="1000" width="100%" marginRight="5" dataProvider="{myArray }" showDataTips="true">

<mx:series>

                        <mx:Array>

                                    <mx:ColumnSeries yField=" myOtherObject.myNumber" />

                        </mx:Array>

            </mx:series>

            <mx:horizontalAxis>

                        <mx:CategoryAxis dataProvider="{myArray}" categoryField="myString" />

            </mx:horizontalAxis>

              <mx:verticalAxis>

                        <mx:LinearAxis interval="100" />

            </mx:verticalAxis>

</mx:ColumnChart>

 

 

The problem is that yField="myOtherObject.myNumber" won’t work ( yField=”myNumber” would work if myObjectX was a flat object but it ain’t…).

I just can’t figure out why I cannot reference a object.field  instead of field in yField? Has anyone figured out this one?

 

Thanks,

Mika
