禁用折线图中的特定图例(Disable a particular legend in a line chart)

 是否有可能在折线图中禁用LineSeries组件的特定图例。 
 
 假设我们有以下代码： 
 
<mx:Panel title="Line Chart">
 <mx:LineChart id="myChart" 
    dataProvider="{expenses}" 
    showDataTips="true"
 >
    <mx:horizontalAxis>
       <mx:CategoryAxis 
            dataProvider="{expenses}" 
            categoryField="Month"
        />
    </mx:horizontalAxis>
    <mx:series>
       <mx:LineSeries 
            yField="Profit" 
            displayName="Profit"
       />
       <mx:LineSeries 
            yField="Expenses" 
            displayName="Expenses"
       />
    </mx:series>
 </mx:LineChart>
 <mx:Legend id="legend" dataProvider="{myChart}"/>
 
 
 它将产生以下折线图： 
 
 
 这就是我想要的结果：

 请记住，我必须使用图例的DataProvider作为myChart，因为数据是动态构建的。 此外，图例是定制的。 

Is there any possibility to disable a particular legend for LineSeries component in a line chart.
 
Let say that we have the following code:
 
<mx:Panel title="Line Chart">
 <mx:LineChart id="myChart" 
    dataProvider="{expenses}" 
    showDataTips="true"
 >
    <mx:horizontalAxis>
       <mx:CategoryAxis 
            dataProvider="{expenses}" 
            categoryField="Month"
        />
    </mx:horizontalAxis>
    <mx:series>
       <mx:LineSeries 
            yField="Profit" 
            displayName="Profit"
       />
       <mx:LineSeries 
            yField="Expenses" 
            displayName="Expenses"
       />
    </mx:series>
 </mx:LineChart>
 <mx:Legend id="legend" dataProvider="{myChart}"/>
 
 
It will produce the following line chart:
 
 
And this the result that i want: 
 
 
UPDATE:
 
Bare in mind that I have to use the legend's DataProvider as myChart because the data is dynamically build. Also, the legend is customized.
