In VBA syntax it's something like

For i = 1 To ActiveWindow.Selection.ShapeRange.Count

    If ActiveWindow.Selection.ShapeRange(i).Type = msoChart Then

        Dim c As Chart
        Set c = ActiveWindow.Selection.ShapeRange(i).Chart

        Dim data As ChartData
        Set data = c.ChartData 
        data.Activate

        data.Workbook.Worksheets(1).Range("B3").Value = _
            data.Workbook.Worksheets(1).Range("B3").Value + 1
        ...

    End If
