WPF AreaSeries：如何更改背景不透明度？

我正在使用WPF工具包中的AreaSeries来实现类似堆栈区域的东西。但是这对于WPF工具包并不是真的可行，所以我将简单地绘制两个系列，而后面的一个是前面系列和“叠加”系列的总和。因此该系列的不透明度应为100％。但是，尽管我将每种可能的不透明度设置为1.0，但该系列仍然有点透明。那么，有谁知道，秘密开关在哪里？WPF AreaSeries：如何更改背景不透明度？

这里是一个片段，所以你可以看到我已经设置不透明度，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
