Data source

private void InitializeChart()
    {
      tChart1.Aspect.View3D = false;
      Contour series = new Contour(tChart1.Chart);

      Steema.TeeChart.Data.TextSource ts = new Steema.TeeChart.Data.TextSource(@"D:\Test Projects\ContourBug\ContourBug\DataFillled.txt");
      ts.HeaderLines = 1;
      ts.DecimalSeparator = '.';
      ts.Separator = ',';
      ts.Fields.Add(0, "X");
      ts.Fields.Add(1, "Y");
      ts.Fields.Add(2, "Z");
      ts.Fields.Add(3, "Text");
      series.XValues.DataMember = "X";
      series.YValues.DataMember = "Y";
      series.ZValues.DataMember = "Z";
      series.DataSource = ts;

      series.FillLevels = true;
    }

DataFilled.txt is attached.

Note the unhandled exception when resizing the chart. With FillLevels commented out, the TextSource performs as expected.
