BoxPlot: NullReferenceException clicking the Series tab in the chart properties

[Ozzard]

 I've created a BoxPlot by feeding it data explicitly (source appended).  When I click the Properties icon on the chart toolbar, then click the Series tab, I get a NullReferenceException deep in Chart FX code:

Is this expected?

-- code sample --
  chart.Series.Clear();
  chart.Data.Clear();

  // Find how many series
  int seriesNumber = 0;
  foreach (Variable v in options.Parameters["data"].AsDataFrame.Variables)
  if (v.IsDoubleVariable)
  seriesNumber++;
  chart.Data.Series = seriesNumber;
  chart.Data.CommitChanges(); // TODO: Why is this necessary?

  // Add the series
  seriesNumber = 0;
  foreach (Variable v in options.Parameters["data"].AsDataFrame.Variables)
  {
  if (v.IsDoubleVariable)
  {
  DoubleVariable dv = v.AsDoubleVariable;
  if (dv.Data.Length > chart.Data.Points)
  chart.Data.Points = dv.Data.Length;
  for (int i = 0; i < dv.Data.Length; i++)
  chart.Data[seriesNumber, i] = dv.Data;

  seriesNumber++;
  }
  }
