我正在使用 WPF Toolkit 中的 AreaSeries 来实现类似堆叠区域的功能。但这对于 WPF 工具包实际上是不可能的，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“堆叠”一个系列的总和。因此，该系列的不透明度应为 100%。但是虽然我将所有可能的不透明度都设置为 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？

这是一个片段，所以你可以看到我已经在哪里设置了不透明度，但没有效果......

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
