get chartobjects from VB.net

Excel.Sheets sheets = oWB.Worksheets;
Excel.Worksheet thisWorksheet = (Excel.Worksheet)sheets.get_Item(1);
Excel.ChartObjects charts =
(Excel.ChartObjects)thisWorksheet.ChartObjects(Type.Missing);
Excel.ChartObject chartObj = (Excel.ChartObject)charts.Item(1);
Excel.Chart chart = chartObj.Chart;
Excel.Axis a =
(Excel.Axis)chart.Axes(Excel.XlAxisType.xlValue,Excel.XlAxisGroup.xlPrimary);
a.MinimumScale = System.Convert.ToDouble(((Excel.Range)oSheet.Cells[2,
5]).Value2);
