WPF AreaSeries：如何更改背景不透明度？

我正在使用WPF工具包中的AreaSeries來實現類似堆棧區域的東西。但是這對於WPF工具包並不是真的可行，所以我將簡單地繪製兩個系列，而後面的一個是前面系列和「疊加」系列的總和。因此該系列的不透明度應爲100％。但是，儘管我將每種可能的不透明度設置爲1.0，但該系列仍然有點透明。那麼，有誰知道，祕密開關在哪裏？WPF AreaSeries：如何更改背景不透明度？

這裏是一個片段，所以你可以看到我已經設置不透明度，效果不...

Dim col As System.Windows.Media.Color 
col = System.Windows.Media.ColorConverter.ConvertFromString("#ff00ff00") 
Dim brush As System.Windows.Media.Brush = New SolidColorBrush(col) 
brush.Opacity = 1.0 
series.Background = brush 
series.Opacity = 1.0 
series.Background.Opacity = 1.0
