I'm trying to produce a simple y vs x plot a la Excel with MSChart. The x and y data  are in the same array and all I want to do is plot y vs. x with a linear scale on both axes. THis should be easy but I can't get it to work.

Dear Iberan,
It is very easy to plot x vs y. I recommend you define your chart on run time.
First of all choose MS Chart Common Controls object and define it on a form (MSChart1).
Afterwards try to locate your x and y values in a data file such as Data.dat
Now, you can write a code to open data file and read x and y values.

    Dim rowCount As Integer
    Dim columnCount As Integer
    Dim DataGrid As DataGrid

MSChart1.chartType = VtChChartType2dX
MSChart1.SeriesType = VtChSeriesType2dXY

                   Open "c:\Data.dat" For Input As #1
            With MSChart1.DataGrid
            rowCount = 4
            columnCount = 5
            .SetSize RowLabelCount, ColumnLabelCount, _
            rowCount, columnCount
         
            For i = 1 To rowCount
                Input #1, X, Y
                .SetData i, 1, X, 0                
                .SetData i, 2, C1, 0
               
            Next i
        End With
                      Close #1
       
   
    With MSChart1.Plot
       
        .UniformAxis = True
        .LocationRect.Max.Y = 5500
        .LocationRect.Min.Y = 0
        .LocationRect.Max.X = 10000
        .LocationRect.Min.X = 800
        .Axis(VtChAxisIdY).AxisTitle.Visible = True
        .Axis(VtChAxisIdX).AxisTitle.Text = "I am X-Axis"
        .Axis(VtChAxisIdY).AxisTitle.Text = "I am Y-Axis"

Now your chart is OK
