我遇到一个问题，即在使用“路径图形”对象时，按下ToggleButton并没有理想的效果。在执行DataTrigger时，它始终与原始路径保持一致。
我的XAML：

还有我的ViewModel类：
namespace Scratch.ViewModels
{
public class ToggleViewModel : Scratch.UiUtilities.PropertyChangedNotifier
{
private bool _nextDayProfitLoss;
public bool NextDayProfitLoss
{
get => _nextDayProfitLoss;
set
{
_nextDayProfitLoss = value;
OnPropertyChanged();
}
}
}
}
调试时，在Visual Studio的“输出”窗口中没有出现任何错误。我应该使用另一种方法吗？我应该改用路径图片吗？我希望尽可能使用所有XAML。
