                    Dim MyCharts1 As Excel.ChartObject
                    MyCharts = excelSheet.ChartObjects
                    'set chart location
                    MyCharts1 = MyCharts.Add(150, 290, 400, 250)

                    oChart = MyCharts1.Chart
                    'use the follwoing line if u want 
                    'to draw chart on the default location
                    'oChart.Location(Excel.XlChartLocation.xlLocationAsObject, excelSheet.Name)

                    Dim R As Integer = datTable.Rows.Count + 1
                    With oChart
                        'set data range for chart
                        Dim chartRange As Excel.Range
                        chartRange = excelSheet.Range("A1", "N" & R)
                        'set how you want to draw chart i.e column wise or row wise

                        '.PlotBy = Excel.XlRowCol.xlColumns

                        .PlotBy = Excel.XlRowCol.xlRows

Hello chtullu,

you need to include the .XValues property in your chart definition

    ActiveChart.SeriesCollection(1).XValues = "=Sheet1!$F$1:$N$1"

cheers, teylyn
