Excel Chart Programming in Vb.Net

Question

I am stuck with a critical issue as explained below:

I am developing a chart programmatically that is saved in an Excel Worksheet with the help of Excel Interop in .Net.

But I cannot use the subscript property of the axis title so that only a part of the title is shown as subscripted and rest will be normal font.

ie.

Dim MyChart As Excel.Chart = CType(MyWorksheet.ChartObjects(1), Excel.ChartObject).Chart

Dim MyAxis As Excel.Axis = CType(MyChart.Axes(Excel.XlAxisType.xlValue), Excel.Axis)

MyAxis.AxisTitle.Text = "cmax"

MyAxis.AxisTitle.Characters(2,3).Font.Subscript = True

Now the above line makes the whole tittle subscripted as if there is no difference in writing the code as :

AxisTitle.Characters().Font.Subscript = True

Any help will be extremely appreciated

This code seems to work in VBA.

VB

ActiveSheet.ChartObjects("Chart 1").Activate
With ActiveChart.Axes(xlCategory)
    .HasTitle = True
    With .AxisTitle
                .Caption = "Revenue (millions)"
                .Font.Name = "bookman"
                .Font.Size = 10
                .Characters(10, 8).Font.Subscript = True
    End With
End With

The only difference is caption vs. text and .HasTitle must be true or the object doesn't exist.
