Wpf 引用错误

我不知道为什么参考文献中有错误。OxyPlot.Wpf.LineSeries到OxyPlot.Series.Series System.Collections.ObjectModel.Collection.AddOxyPlot.Axis.Axis的最佳重载方法匹配具有一些无效参数

听起来您在使用不同的名称空间时遇到了一些问题。我不能说我完全理解您的尝试，因此这可能不会给您期望的结果，但我通过nuget安装OxyPlot.Wpf后，能够使用以下名称空间编译您的代码：

using OxyPlot;
using OxyPlot.Axes;
using OxyPlot.Series;

如果您在OxyPlot.Wpf名称空间中发现某些特定行为，那么这可能对您没有帮助
