hi my code is
Dim xmlpath = "C:\Users\Kiran\AppData\Roaming\SRSConnectGraphs\Settings\Customers\Manohar.xml"
Dim ds1 As New DataSet()
Dim xmlfile1 As XmlReader
xmlfile1 = XmlReader.Create(xmlpath, New XmlReaderSettings())
ds1.ReadXml(xmlfile1)

'While xmlfile1.Read()

Dim xmldoc As New XmlDocument()
xmldoc.Load(xmlpath)

Dim nodeList As XmlNodeList = xmldoc.SelectNodes("//NewDataSet/Set")
For Each node As XmlNode In nodeList
Dim custname As String = node("CustomerName").InnerText
lblCustName.Text = custname
Next

If (lblCname.Text = lblCustName.Text) Then
With locWorkbook.Worksheets(1).Range("A5:B5")
With .Font
.Name = "Arial"
.FontStyle = "Bold"
.Size = 12
End With
With .Interior
.ColorIndex = 15
End With
End With

For i = 4 To ds1.Tables(0).Columns.Count - 1
locWorksheet.Cells(i + 1, 2) = ds1.Tables(0).Rows(0).Item(i)
locWorksheet.Cells(i, 1).BorderAround(Excel.XlLineStyle.xlContinuous)
locWorksheet.Cells(i, 2).BorderAround(Excel.XlLineStyle.xlContinuous)
Next

End If

VB

'For Chart generation
       xlCharts = locWorksheet.ChartObjects
       myChart = xlCharts.Add(100, 80, 300, 250)
       chartPage = myChart.Chart
       chartRange = locWorksheet.Range("B5", "B" & ds.Tables(0).Columns.Count - 1)
       chartPage.SetSourceData(Source:=chartRange)
       chartPage.ChartType = Excel.XlChartType.xlLine
       chartPage.HasTitle = True
       chartPage.ChartTitle.Text = "Wipro Cylinder Test Rig.."

and my xml file is
