ASP.net Dynamically building a Chart using a GridView

Hi

I am trying to build the chart from the GridView shown in the image dynamically
using the VB.net code below.
How do I add the Company names and years to the X axis

 
   Sub oChart(ByVal RowFields As String, ByVal DataField As String, ByVal sAggregate As String, ByVal ColumnFields As String, oChartID As String, ByVal oRow As Integer, ByVal oColumn As Integer, ByVal blnShow_Data_With_Chart As Boolean)
        ' Initialize the Chart object    
        Dim chart1 As New Chart()
        'chart1.ID = "chart1"

        'Add to do code here
        If Not IsPostBack Then
            ' Initialize objects and elements
            Dim chartArea1 As New ChartArea()
            Dim legend1 As New Legend()
            Dim series1 As New Series()
            Dim series2 As New Series()
            Dim series3 As New Series()

            ' Set the Chart Properties
            chart1.Width = 340
            chart1.Height = 340

            chart1.Palette = ChartColorPalette.EarthTones
            chart1.Palette = ChartColorPalette.Excel
            chart1.BackColor = System.Drawing.Color.Gray
            chart1.BorderSkin.SkinStyle = BorderSkinStyle.Emboss

            chart1.BorderlineColor = System.Drawing.Color.Gray
            chart1.BorderlineDashStyle = ChartDashStyle.Solid
            chart1.BorderlineWidth = 4

            ' Set the ChartArea properties
            chartArea1.Name = "Default"
            chartArea1.BackColor = System.Drawing.Color.Gray

            'Enable AJAX features such as zooming and scrolling for the ChartArea
            'chartArea1.CursorX.UserEnabled = True
            'chartArea1.CursorY.UserEnabled = True
            'chartArea1

            ' Add the ChartArea to the Chart
            chart1.ChartAreas.Add(chartArea1)

            ' Set the Legend properties
            legend1.Name = "Default"
            legend1.Docking = Docking.Bottom
            legend1.LegendStyle = LegendStyle.Row
            legend1.Alignment = System.Drawing.StringAlignment.Center

            legend1.BackColor = System.Drawing.Color.Transparent
            legend1.BorderColor = System.Drawing.Color.Black
            legend1.BorderWidth = 1

            ' Add the Legend to the Chart
            chart1.Legends.Add(legend1)

            ' Set the Series properties
            series1.BorderColor = System.Drawing.Color.DarkSlateGray
            series1.Name = "Series1"
            series1.ChartType = SeriesChartType.SplineArea

            series2.BorderColor = System.Drawing.Color.DarkSlateGray
            series2.Name = "Series2"
            series2.ChartType = SeriesChartType.Column


            series3.Name = "Series3"
            series3.BorderWidth = 3
            series3.ChartType = SeriesChartType.Spline

            ' Add the Series to the Chart
            chart1.Series.Add(series1)
            chart1.Series.Add(series2)
            chart1.Series.Add(series3)

            ' Add points to each series.
            Dim rnd As New Random()
