是否可以在线系列图的两个点之间画一条线？

Question

在这里，我给出了3和4的值，并在图中指出了该值。而不是指向一个点，可以在3到4之间画一条线

后面的代码

   private void Button_Click(object sender, RoutedEventArgs e)
    {
        LineSeries ls = new LineSeries();
        string inputX = this.t1.Text.ToString();
        int inputY = Convert.ToInt32(this.t2.Text.ToString());
        ChartValues.Add(new KeyValuePair<string, int>(inputX, inputY));

        ls.Title = "temperature";
        ls.IndependentValueBinding = new Binding("Key");
        ls.DependentValueBinding = new Binding("Value");
        ls.ItemsSource = ChartValues;
        mchart.Series.Add(ls); 
    }
