为什么ChartPlotter没有AddLineGraph方法

[dhr2001]

手头有个项目需要通过动态曲线显示传感器的值。
网上说使用DynamicDataDisplay最方便，新建了一个WPF应用(.NET Framework)。
通过“管理NuGet程序包”方式获取的DynamicDataDisplayWpf，版本是0.4.0。
现在的情况是AddLineGraph方法不能用，导致不能动态曲线。请帮忙分析一下原因，折腾一整天了！

XAML代码如下：
<Window x:Class="DataDisplayTest.MainWindow"

</StackPanel>
<d3:ChartPlotter x:Name="plotter" Margin="10,10,20,10" Grid.Row="1">

<d3:VerticalIntegerAxis />
</d3:ChartPlotter.MainVerticalAxis>

</d3:ChartPlotter.MainHorizontalAxis>
<d3:Header Content="传感器测试"/>
<d3:VerticalAxisTitle Content="浓度"/>
</d3:ChartPlotter>
</Grid>
</Window>

private DispatcherTimer timer = new DispatcherTimer(); //委托的定时器
int i = 0; //时间轴

public MainWindow()
{
InitializeComponent();
this.Loaded += new RoutedEventHandler(Window_Loaded);
}

//**** 时间，用于构造坐标点
private void AnimatedPlot(object sender,EventArgs e) {
cpuPerformance.CategoryName = "Processor";
cpuPerformance.CounterName = "% Processor Time";
cpuPerformance.InstanceName = "_Total";

double x = i;
double y = cpuPerformance.NextValue();

Point point = new Point(x,y); //点
dataSource.AppendAsync(base.Dispatcher,point); //将点异步委托到数据源
cpuUsageText.Text = String.Format("{0:0%}",y); //格式化显示CPU使用率
i++; //时间+1
}

//窗口加载完毕后触发
private void Window_Loaded(object sender, EventArgs e) {
//******* 这里AddLineGraph不能用
plotter.AddLineGraph(dataSource,Colors.Green,2, "Percentage"); //这里提示ChartPlotter未包含AddLineGraph
//********
timer.Interval = TimeSpan.FromSeconds(1);
timer.Tick += new EventHandler(AnimatedPlot);
timer.IsEnabled = true;
plotter.Viewport.FitToView();
}
}
}

没找到问题原因，估计是因为DynamicDataDisplay的版本更新后，把一些方法去除了。
现调整为下面这种方式实现。

LineGraph line = new LineGraph();
line.DataSource = dataSource;
line.Stroke = Brushes.Green;
line.StrokeThickness = 2;
line.AddToPlotter(plotter);
