I am wondering how will i proceed with the following requirement. I need to create a line chart of business data of the last 8 quarters. It is easy, but the requirement is that, there should not be a connection between last year's Q4 and this years Q1. In effect, using the same array collection i need to split the line chart so that it looks like two diffferent lines on the same chart. Any idea how to proceed with it.

Thanks, PK

首先，您可以通过 Array Collection 中的条件添加多行系列：

<mx:series>
           <mx:LineSeries 
                yField="Profit" 
                displayName="Profit"
           />
           <mx:LineSeries 
                yField="Expenses" 
                displayName="Expenses"
           />
        </mx:series>

您可以使用标签更改每个系列的线条的宽度和颜色。使每条线具有不同的笔触和颜色。

        {Month:"Feb", Profit:1000, Expenses:200, Amount:600},
        {Month:"Mar", Profit:1500, Expenses:500, Amount:300}
     ]);
  ]]></mx:Script>
