Trying that again (Google Chrome and Forum are not friends)

Hi all,
I am having a hard time figuring out how to setup and populate a scatterlinechart. I am working within a chartfactory that currently produces BarCharts and areacharts by passing a DataRow object to the UpdateChart method.
I have many XY points on each 'line' and expect to plot 2 lines.
Any help greatly appreciated.
thx

InitializeChart()
case Shared.EChartType.Scatter:
  this.Chart.ChartType = Infragistics.UltraChart.Shared.Styles.ChartType.ScatterLineChart;
  this.dataSetMonitorSailMap.Tables.Clear();
  this.dataSetMonitorSailMap.Tables.Add();
  this.dataSetMonitorSailMap.Tables[0].Clear();
  { this.dataSetMonitorSailMap.Tables[0].Columns.Add("ColumnX", typeof(double)); 
     this.dataSetMonitorSailMap.Tables[0].Columns.Add("ColumnY", typeof(double));
...

InitializeRowData()
  case Shared.EChartType.Scatter:
  //rowData is an empty ArrayList[2] object
  // Add Row(s) to DataSet Table
  rowData[0] = new ArrayList();
  rowData[1] = new ArrayList();

                      for (int i = 0; i < sensorCount; i++)
                    {
                        rowData[0].Add((double)i);
                        rowData[1].Add((double)i);
                     }

                    row = this.dataSetMonitorSailMap.Tables[0].NewRow();
                    row.ItemArray = rowData[0].ToArray();
                    this.dataSetMonitorSailMap.Tables[0].Rows.Add(row);
                    row = this.dataSetMonitorSailMap.Tables[0].NewRow();
                    row.ItemArray = rowData[1].ToArray();
                    this.dataSetMonitorSailMap.Tables[0].Rows.Add(row);

UpdateChart()
