title: labeling a legend in epplus
body: <p>I'm trying to create a graph from some data I export to an .xls file.  I create the graph just fine, but I'm going to have anywhere from 3 - 7 lines on the graph.  I added the legend to make it easier to read, but the legend has no text on it.  It just shows a line without a label.  Is there anyway to label the legend key?</p>
  
  <p>Here's the code of the graph I'm making:</p>
  
  <pre><code>    var lineChart = ws.Drawings.AddChart(item.TestHeader, eChartType.Line) as ExcelLineChart;
      lineChart.SetSize(800, 400);
  
      lineChart.Series.Add(Char.ConvertFromUtf32(65 + distanceCount + 1).ToString() + "1:" + Char.ConvertFromUtf32(65 + distanceCount + 1).ToString() + (testCount.ToString()), "A1:A" + (testCount.ToString()));
  
      lineChart.Title.Text = item.TestHeader;
      lineChart.DataLabel.ShowSeriesName = true;
      lineChart.DataLabel.ShowLegendKey = true;
      lineChart.DataLabel.ShowLeaderLines = true;
      lineChart.XAxis.Title.Text = "Inches from Decoder";
      lineChart.YAxis.Title.Text = "Milliseconds to decode";
      lineChart.YAxis.MaxValue = 1000;     
  </code></pre>
  
  <p>Any help is better than none, thanks!</p>
