title: How to swap axes in WPF Toolkit line chart?
body: <p>How does one swap the axes in a WPF Toolkit line chart? I have the following xaml:</p>
  
  <pre><code>&lt;chartingToolkit:Chart  Name="lineChart" Title="Line Series Demo" Margin="0,0,0,0"&gt;
       &lt;chartingToolkit:LineSeries  DependentValuePath="Key" IndependentValuePath="Value" ItemsSource="{Binding}" IsSelectionEnabled="True" /&gt;
    &lt;/chartingToolkit:Chart&gt;
  </code></pre>
  
  <p>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. </p>
