Chart Data from VBA not Cells

I want to know if it is possible to set the data to a chart from VBA code without having to set it to a bunch of cells.

For the purpose, it can plot anything.. even random numbers. But I don't want to use any cells to paste the values and then do the chart get these values.

[My application has a Sheet with a lot of letters "M" (maintenance), "O" (opperating) and "A" (available), for everyday of the year, from a bunch of equipments. I do some vba filtering on the equipments to get some that I want to plot and want to do some calculations based on the "M", "O" and "A" quantities.]

Here's a simple example:

Sub AddChart()
    Dim cht     As Chart
    Dim ser     As Series

    Set cht = Charts.Add
    cht.ChartType = xlColumnClustered
    Set ser = cht.SeriesCollection.NewSeries
    ser.XValues = Array(1, 3, 5, 7, 9)
    ser.Values = Array(2.4, 3.2, 5.7, 12.67)
End Sub

You must note that the SERIES formula for a chart in some versions (2003 and prior, I think) is limited to 1024 characters. In 2010, it seems to be limited to 8192 characters. That means that if you use literal values (rather than a range) for the data, each character is included in the formula - so the more decimal places you specify and the more data points, the more likely the code will fail.
