在按钮上绘制折线图 单击
Plot line graph on button Click
我正在开发 wpf application.In，我需要在单击按钮时绘制实时图表。
我试着写 this.MyModel.InvalidatePlot(true);在点击（）。

我希望在添加系列后更新数据上下文。请为此提出解决方案。
你在这里混合了太多的想法。如果您正在使用 PlotView 并且还使用所需系列定义了模型，则您需要做的就是绑定模型。
<Grid>
<oxy:PlotView x:Name="Plot1" Model="{Binding MyModel}" Margin="8,11,12,97" />
</Grid>
由于您的模型已经具有绘制线系列的详细信息，因此它会自行绘制线系列。
我正在开发 wpf application.In，我需要在单击按钮时绘制实时图表。

System.Diagnostics.Debug.WriteLine(XValues[i] + "," + YValues[i]);
series.Points.Add(new DataPoint(XValues[i], YValues[i]));
}
plot.Series.Add(series);
this.MyModel = plot;
this.DataContext = this;
this.MyModel.InvalidatePlot(true);
System.Diagnostics.Debug.WriteLine(MyModel.Series.Count);

我希望在添加系列后更新数据上下文。请为此提出解决方案。
你在这里混合了太多的想法。如果您正在使用 PlotView 并且还使用所需系列定义了模型，则您需要做的就是绑定模型。
<Grid>
<oxy:PlotView x:Name="Plot1" Model="{Binding MyModel}" Margin="8,11,12,97" />
</Grid>
由于您的模型已经具有绘制线系列的详细信息，因此它会自行绘制线系列。
