Xaml 如何更改面积图中的DependentRangeAxis

我正在使用WinRT toolkit AreaChart，我需要直接在XAML代码中更改DependentRangeAxis，我想设置一个从1到5的固定范围

<Series:Chart
            x:Name="QuestionHistory"
            Title="Area Chart">
        <Series:AreaSeries 
            Title="MediaRisposte"
            AnimationSequence="LastToFirst"
            IndependentValueBinding="{Binding Name}"
            DependentValueBinding="{Binding Value}"
            DependentRangeAxis="???"
            IsSelectionEnabled="True" />
    </Series:Chart>

先谢谢你

 ((BarSeries)this.LikesChart.Series[0]).IndependentAxis = new LinearAxis() { Minimum = 0, Maximum = 5, Orientation = AxisOrientation.Y };
