如何在 WPF Toolkit 折线图中交换轴？

如何交换 WPF 工具包折线图中的轴？我有以下 xaml：

<chartingToolkit:Chart  Name="lineChart" Title="Line Series Demo" Margin="0,0,0,0">
     <chartingToolkit:LineSeries  DependentValuePath="Key" IndependentValuePath="Value" ItemsSource="{Binding}" IsSelectionEnabled="True" />
  </chartingToolkit:Chart>

从属值始终显示为 Y 轴。我需要它们作为 X 轴。这可以通过 WPF Toolkit 图表实现吗？如果我无法使用 WPF Toolkit 执行此操作，是否可以使用其他免费的 WPF 图表库？我所需要的只是能够处理 X 轴上的时间和 Y 轴上的字符串的多个系列的折线图。

How does one swap the axes in a WPF Toolkit line chart? I have the following xaml:

<chartingToolkit:Chart  Name="lineChart" Title="Line Series Demo" Margin="0,0,0,0">
     <chartingToolkit:LineSeries  DependentValuePath="Key" IndependentValuePath="Value" ItemsSource="{Binding}" IsSelectionEnabled="True" />
  </chartingToolkit:Chart>

The dependent values always appear as the Y-axis. I need them as the X-axis. Is this possible with WPF Toolkit charts? If I can't do this with WPF Toolkit, are there other free WPF charting libraries I can use instead? All I need is line chart that can handle multiple series with time on X-Axis and Strings on Y-Axis.

在尝试使用原始 WPF 工具包找到问题的答案失败后，我决定自己编辑图表工具包源代码。以下是我为了使其正常工作而所做的更改：（

显示源代码更改，要查看原始源代码，请在编辑之前查看原始帖子）

获取源代码。我正在使用 VS2010，因为一些组件
从WPF Toolkit已经成为.NET4的一部分，我不得不修改WPF
工具包解决方案。值得庆幸的是，这些跑腿工作已经为我完成了。
此处获取源代码

将 LineSeries.cs:115 更改为

 if (轴 == null)
                {
                   轴=新的CategoryAxis();
                }

将 LineAreaBaseSeries.cs:243 更改为

 double x = ActualIndependentAxis.GetPlotAreaCooperative(dataPoint.ActualIndependentValue).Value;
   double y = this.InternalActualDependentAxis.GetPlotAreaCooperative(dataPoint.ActualDependentValue).Value;

   if (ValueHelper.CanGraph(x) && ValueHelper.CanGraph(y))
   {
      dataPoint.Visibility = Visibility.Visible;

      双坐标Y = Math.Round(y - (dataPoint.ActualHeight / 2));
      Canvas.SetTop(dataPoint, 坐标Y);
      双坐标X = Math.Round(x - (dataPoint.ActualWidth / 2));
      Canvas.SetLeft(dataPoint, 坐标X);
   }
   别的
   {
      dataPoint.Visibility = Visibility.Collapsed;
   }

LineAreaBaseSeries.cs:298 更改为

       Func<DataPoint, Point> createPoint =
           dataPoint =>
               new Point(
                   ActualIndependentAxis.GetPlotAreaCoordinate(dataPoint.ActualIndependentValue).Value,
                   this.InternalActualDependentAxis.GetPlotAreaCoordinate(dataPoint.ActualDependentValue).Value);
       IEnumerable<Point> points = Enumerable.Empty<Point>();
       if (ActualIndependentAxis is IRangeAxis)
       {
          points = DataPointsByIndependentValue.Select(createPoint);
       }
       else
       {
          points =
             ActiveDataPoints
                   .Select(createPoint)
                   .OrderBy(point => point.X);
       }

在这些更改之后，您可以使用依赖的字符串源。

干杯!

After unsuccessfully trying to find an answer to my problem with the original WPF Toolkit, I decided to edit the Charting toolkit source myself. Here are the changes that I did in order to get it working:

(Showing source code changes, to see original source, look at the original post prior to edit)

Get the source. I am using VS2010 and since some of the components
from WPF Toolkit have become a part of .NET4, I had to modify WPF
Toolkit solution. Thankfully, that legwork was already done for me.
Get the source here

Change LineSeries.cs:115 To

                if (axis == null)
                {
                   axis = new CategoryAxis();
                }

Change LineAreaBaseSeries.cs:243 To

   double x = ActualIndependentAxis.GetPlotAreaCoordinate(dataPoint.ActualIndependentValue).Value;
   double y = this.InternalActualDependentAxis.GetPlotAreaCoordinate(dataPoint.ActualDependentValue).Value;

   if (ValueHelper.CanGraph(x) && ValueHelper.CanGraph(y))
   {
      dataPoint.Visibility = Visibility.Visible;

      double coordinateY = Math.Round(y - (dataPoint.ActualHeight / 2));
      Canvas.SetTop(dataPoint, coordinateY);
      double coordinateX = Math.Round(x - (dataPoint.ActualWidth / 2));
      Canvas.SetLeft(dataPoint, coordinateX);
   }
   else
   {
      dataPoint.Visibility = Visibility.Collapsed;
   }

Change LineAreaBaseSeries.cs:298 To

       Func<DataPoint, Point> createPoint =
           dataPoint =>
               new Point(
                   ActualIndependentAxis.GetPlotAreaCoordinate(dataPoint.ActualIndependentValue).Value,
                   this.InternalActualDependentAxis.GetPlotAreaCoordinate(dataPoint.ActualDependentValue).Value);
       IEnumerable<Point> points = Enumerable.Empty<Point>();
       if (ActualIndependentAxis is IRangeAxis)
       {
          points = DataPointsByIndependentValue.Select(createPoint);
       }
       else
       {
          points =
             ActiveDataPoints
                   .Select(createPoint)
                   .OrderBy(point => point.X);
       }

After these changes you can use a dependent source of strings.

Cheers!
