zakman,

here's a sub which takes a column in DBGrid and makes an Excel bar chart of the data

Private Sub MakeBarChart(nDBGridCol As Integer, nExcelCol As Integer)
    Dim objXLsheet As Object
    Dim objRange As Object
    Dim objChart As Object

    Dim nPoints As Integer

    Form1.MousePointer = vbHourglass
     
    ' Create a Worksheet Object:
    Set objXLsheet = CreateObject("Excel.Sheet")

    ' Insert data into an Excel column from a DBGrid's column
    nExcelCol = 1
    nDBGridCol = 1
    With Form1.DBGrid1
        .Col = nDBGridCol
        Data1.Recordset.MoveFirst
        nPoints = 1
        While Not Data1.Recordset.EOF
            objXLsheet.Cells(nPoints, nExcelCol).Value = CInt(DBGrid1.Text)
            Data1.Recordset.MoveNext
            nPoints = nPoints + 1
        Wend
    End With
           
    ' Add a ChartObject to the worksheet:
    Set objChart = objXLsheet.ChartObjects.Add(100, 100, 200, 200)

    ' Assign the column created above as a series for the chart:
    objChart.Chart.SeriesCollection.Add objXLsheet.Columns(nExcelCol), xlColumns

    ' Make Excel Visible:
    objXLsheet.Application.Visible = True
    DoEvents

    ' Save the Worksheet to disk.
    objXLsheet.Parent.SaveAs "C:\XLCHART.XLS"

    ' Close this instance of Excel:
    objXLsheet.Application.Quit
    MousePointer = vbArrow
End Sub
