引用错误

Question

我不确定为什么参考文献中有错误。 OxyPlot.Wpf.LineSeries到OxyPlot.Series.Series System.Collections.ObjectModel.Collection.Add(OxyPlot.Axes.Axis)的最佳重载方法匹配包含一些无效参数。

听起来你遇到了一些不同命名空间的问题。我不能说我完全明白你在尝试什么，所以这可能不会给你想要的结果，但我能够使用以下命名空间（通过nuget安装了OxyPlot.Wpf）来编译代码：

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

如果事实证明你是在追踪OxyPlot.Wpf名称空间中的某些特定行为后，这可能会对你没有帮助。
