wpf工具包散点图

Question

我从来没有对这个 wpf 工具包如此恼火。文档根本不存在！啊。

究竟如何连接散点图中的线条？

我需要生成一个跨多个系列的线性图。我使用 Excel 散点图很好地制作了我需要做的事情的原型，但我一生都无法弄清楚如何连接工具包中的点。

这是代码，我是否缺少一个选项？

<my:Chart Name="myChart" Margin="5,5,5,5" Opacity="1" Width="525">
</my:Chart>

ScatterSeries a = new ScatterSeries();
a.Title = "a";

a.IndependentValuePath = "Key";
a.DependentValuePath = "Value";
myChart.Series.Add(a);

a = new ScatterSeries();
a.Title = "b";
a.IndependentValuePath = "Key";
a.DependentValuePath = "Value";
myChart.Series.Add(a);

((ScatterSeries)myChart.Series[0]).ItemsSource = new KeyValuePair<DateTime, int>[]
 {
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(1), 0),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(2), 150),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(3), 150),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(4), 0),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(5), 0),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(8), 130),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(9), 130),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(10), 0),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(11), 0),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(15), 225),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(16), 225),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(17), 0)
 };


((ScatterSeries)myChart.Series[1]).ItemsSource = new KeyValuePair<DateTime, int>[]
{
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(-21), 0),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(-5), 750),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(3), 750),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(7), 0),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(9), 0),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(10), 330),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(19), 330),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(20), 0),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(21), 0),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(25), 525),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(26), 525),
   new KeyValuePair<DateTime, int>(DateTime.Now.AddMonths(27), 0)
};

散点图不将点与线连接起来。使用 LineSeries 应该将这些点连接起来。
