title: Changing and setting the Legend (LineGraph) Future of DynamicDataDisplay
body: <p>I'm using this great library <a href="https://d3future.codeplex.com/" rel="nofollow">https://d3future.codeplex.com/</a> to plot some 2D graphs.</p>
  
  <p>In the old D3 I used to set the legend this way:</p>
  
  <pre><code>graf = plotter.AddLineGraph(new CompositeDataSource(xSrc, plot),
                       new Pen(brush, 4),
                       new PenDescription("myText" ));
  </code></pre>
  
  <p>But I have no idea how to obtain the same in <em>future D3</em>. Could someone make me see the light?</p>
  
  <p>Exploring the <strong>source code</strong> I find this but can't understand how to access and change the default string "LineGraph":</p>
  
  <pre><code>    public class LineGraph : PointsGraphBase
          {
              static LineGraph()
              {
                  Type thisType = typeof(LineGraph);
  
                  Legend.DescriptionProperty.OverrideMetadata(thisType, new FrameworkPropertyMetadata("LineGraph"));
                  Legend.LegendItemsBuilderProperty.OverrideMetadata(thisType, new FrameworkPropertyMetadata(new LegendItemsBuilder(DefaultLegendItemsBuilder)));
              }
  //more stuff
  
  }
  </code></pre>
