Excel Chart Formatting / Axes

I'm running into a problem with Excel 2003 and VB.NET 2003.   My code is working mostly, but I'm having some trouble formating certain elements of the chart object.  The main problem is that I need the lables on the axis rotated using the orientation value.    I've included the code used to build the chart below, what I can't figure out is how to make the X-Axes values rotate 90 degrees.

Any help is greatly appreciated.
       Dim RangePeriod As Object
        Dim RangePercent As Object
        Dim finalCell As String = "C" & ds.Tables(0).Rows.Count + 1
        Dim FinalPctCell As String = "H" & ds.Tables(0).Rows.Count + 1
 
        '' set the range value
        RangePeriod = worksheet.Range("C2", finalCell)
        RangePercent = worksheet.Range("H2", FinalPctCell)
 
        ' The following code draws the chart
        Dim chartobjects As Object
        chartobjects = worksheet.ChartObjects(Missing.Value)
 
        Dim chartobject As Object
         ''chartObjects.Add(Left,Top,Width,Height)
        chartobject = chartobjects.Add(0, 0, 750, 650)
 
        Dim chart As Object
        chart = chartobject.Chart
 
        Dim source As Object = RangePercent
        Dim Gallery As Object = Excel.XlChartType.xl3DColumn
        Dim Format As Object = Missing.Value
        Dim PlotBy As Object = Excel.XlRowCol.xlColumns
        Dim CategoryLabels As Object = 0
        Dim SeriesLables As Object = 0
        Dim HasLegend As Object = False
        Dim Title As Object = "Chart"
        Dim ValueTitle As Object = "Dates"
        Dim ExtraTitle As Object = "Percent"
 
        Try
            chart.ChartWizard(source, Gallery, Format, PlotBy, CategoryLabels, SeriesLables, HasLegend, Title, _
                ValueTitle, ExtraTitle)
 
        Catch ex As Exception
            Throw ex
        End Try
 
 
        Dim oSeries As Excel.Series
        oSeries = chart.SeriesCollection(1)
        oSeries.XValues = RangePeriod
 
        Dim xlAxisCategory, xlAxisValue
 
        xlAxisCategory = CType(chart.Axes(, Excel.XlAxisGroup.xlPrimary), Excel.Axes)
        xlAxisCategory.Item(Excel.XlAxisType.xlCategory).HasTitle = True
 
        xlAxisValue = CType(chart.Axes(, Excel.XlAxisGroup.xlPrimary), Excel.Axes)
        xlAxisValue.Item(Excel.XlAxisType.xlValue).HasTitle = True

Perhaps I'm missing something obvious but when I add:
ActiveChart.Axes(xlAxisValue).select

I get: 'ActiveChart.Axes' is not declared or the module containing it is not loaded in the debugging session.

hmm, tried that earlier and got

xlaxisvalue.select

Run-time exception thrown : System.MissingMemberException - Public member 'select' on type 'Axes' not found.

I must have it defined it incorrectly.  Is there no simple method to SELECT the values of one the Axes?

again, I know i'm missing the obvious, but that causes the following exception:

System.Runtime.InteropServices.COMException - Unable to get the Axes property of the Chart class

Not sure if it helps but here are the last few lines where it's breaking.

        Dim xlAxisCategory, xlAxisValue
 
        xlAxisCategory = CType(chart.Axes(, Excel.XlAxisGroup.xlPrimary), Excel.Axes)
        xlAxisCategory.Item(Excel.XlAxisType.xlCategory).HasTitle = True
 
        xlAxisValue = CType(chart.Axes(, Excel.XlAxisGroup.xlPrimary), Excel.Axes)
        xlAxisValue.Item(Excel.XlAxisType.xlValue).HasTitle = True
 
        chart.ChartArea.Border.Weight = Excel.XlBorderWeight.xlThick
 
        '' THE FOLLOWING LINE CAUSES THE EXCEPTION
        chart.Axes(xlAxisValue).select()
        '' end

That makes sense, but I've yet to see a better way of defining the objects.  Any advise on where to check?

Thanks!

Well lets go back to basic...try making a chart by recording macro...by making a chart...and wherever the data points are variable..lets define it to what we want to do...and by this way this thing will be resolved...

We'll after messing around with it some more, the issue was indeed the method in which I was creating the objects.  By declaring them as the proper types, I was finally able to select the axis, and make the changes required.

See Code:
        Dim xlAxisCategory As Excel.Axes
        xlAxisCategory = chart.Axes(, Excel.XlAxisGroup.xlPrimary)
        xlAxisCategory.Item(Excel.XlAxisType.xlCategory).HasTitle = True
 
        xlAxisCategory.Item(Excel.XlAxisType.xlValue).Select()
 
        With app.Selection.TickLabels
            .Orientation = Excel.XlOrientation.xlDownward
        End With
