I am drawing an excel chart using C#. But the chart is occupying entire plot
area no matter how many rows i give. I want to leave some space at the end of
the chart.



Suppose i am drawing chart for 400 rows, I want to see all the 400 rows on
the x axis without omitting the blank rows. How can i do that.



Following is my code




Code Block/* Open the destination file */

xlBookScript = (Excel.Workbook)xlBooks.Open(sDestinationFile, Type.Missing,
Type.Missing,

Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing,

Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing);

xlSheetExtra = (Excel.Worksheet)xlBookScript.Worksheets["Extra"];

xlSheetScript = (Excel.Worksheet)xlBookScript.Worksheets[sSheetType];

xlChart = (Excel.Chart)xlBookScript.Charts.Add(Type.Missing, Type.Missing,
Type.Missing, Type.Missing);

xlRange = xlSheetScript.get_Range("B7:B400,D7:D400,J7:J400,O 7:O400",
Type.Missing);

xlChart.ChartWizard(xlRange, Excel.XlChartType.xlLineMarkers, Type.Missing,

Excel.XlRowCol.xlColumns, Type.Missing, Type.Missing, false,

sSheetType, Type.Missing, Type.Missing, Type.Missing);







xlSeriesVol = (Excel.Series)xlChart.SeriesCollection(4);

xlSeriesVol.AxisGroup = Excel.XlAxisGroup.xlSecondary;

xlSeriesVol.ChartType = Excel.XlChartType.xlColumnClustered;

xlZAxis = (Excel.Axis)xlChart.Axes(Excel.XlAxisType.xlValue,
Excel.XlAxisGroup.xlSecondary);

xlZAxis.TickLabelPosition = Excel.XlTickLabelPosition.xlTickLabelPositionNone;

xlZAxis.MajorTickMark = Excel.XlTickMark.xlTickMarkNone;

xlZAxis.MaximumScale = 3 * xlZAxis.MaximumScale;

xlZAxis.MinimumScale = 0;







/* Give the location for the chart */

xlChart.Location(Excel.XlChartLocation.xlLocationA sObject, "Extra");

xlRange = (Excel.Range)xlSheetExtra.Rows.get_Item(iRowNo, Type.Missing);

xlSheetExtra.Shapes.Item(sChartNo).Top = (float)(double)xlRange.Top;

xlRange = (Excel.Range)xlSheetExtra.Columns.get_Item(1, Type.Missing);

xlSheetExtra.Shapes.Item(sChartNo).Left = (float)(double)xlRange.Left;

xlSheetExtra.Shapes.Item(sChartNo).Height = 380;

xlSheetExtra.Shapes.Item(sChartNo).Width = 710;

xlBookScript.Close(true, Type.Missing, Type.Missing);

Is the first column for X values? Does row 7 contain column headers? If both
of these answers are "yes", then clear cell B7. If only the first is true,
put headers in D6, J6, and O6, and make sure B6 is blank, and extend the
range to include row 6.
