I am reading an excel chart using interop and exporting in to a word file. Now, I want to achieve the same purpose using NPOI library. The code which I have used to read an excel chart is as follows: -

 Microsoft.Office.Interop.Word.Table myWordable; 
   Microsoft.Office.Interop.Word.Range myWordRange;
   FileStream myfile = Path.Combine(filepath, "Test_Excel.xlsx");
   using (ExcelPackage package = new ExcelPackage(myfile))
   {
        ExcelWorksheet myws = package.Workbook.Worksheets[1];
        myWordTable = new_mach.myWordApplication.ActiveDocument.Tables[5];
        myWordRange = new_mach.myWordTable.Cell(2, 1).Range;
        Microsoft.Office.Interop.Word.InlineShape objshape =        new_mach.myWordDoc.InlineShapes.AddChart(Microsoft.Office.Core.XlChartType.xlXYScatterSmoothNoMarkers, new_mach.myWordRange);
        Microsoft.Office.Interop.Word.Chart mychrt = objshape.Chart;
        Workbook wb = mychrt.ChartData.Workbook;
        Worksheet datasheet = wb.Worksheets["Sheet1"];
        Microsoft.Office.Interop.Excel.Range myrng = datasheet.get_Range("A1","D10");
        Microsoft.Office.Interop.Excel.ListObject tbl = datasheet.ListObjects["Table1"];
        tbl.Resize(myrng);

        mychrt.HasLegend = true;
        mychrt.Legend.Position = Microsoft.Office.Interop.Word.XlLegendPosition.xlLegendPositionBottom;
        mychrt.Legend.Format.Line.Style = Microsoft.Office.Core.MsoLineStyle.msoLineSingle;
        mychrt.Legend.Format.Line.Visible = Microsoft.Office.Core.MsoTriState.msoCTrue;
        Microsoft.Office.Interop.Word.Series sr = mychrt.SeriesCollection(1);

        sr.Border.Color = Color.Red;
        sr.Name = "Charging";
        sr = mychrt.SeriesCollection(2);
        sr.Name = "Discharging";
        sr.Border.Color = Color.Navy;
        Microsoft.Office.Interop.Word.Axis vertaxis = (Microsoft.Office.Interop.Word.Axis)mychrt.Axes(Microsoft.Office.Interop.Word.XlAxisType.xlValue, Microsoft.Office.Interop.Word.XlAxisGroup.xlPrimary);
        vertaxis.HasMajorGridlines = true;
        vertaxis.HasTitle = true;
        vertaxis.AxisTitle.Text = "Pol-Depol Currents (microAmp)";
        vertaxis.HasMinorGridlines = true;
        vertaxis.LogBase = 10;

        Microsoft.Office.Interop.Word.Axis Horiaxis = (Microsoft.Office.Interop.Word.Axis)mychrt.Axes(Microsoft.Office.Interop.Word.XlAxisType.xlCategory, Microsoft.Office.Interop.Word.XlAxisGroup.xlPrimary);
        Horiaxis.HasMajorGridlines = true;
        Horiaxis.HasTitle = true;
        Horiaxis.AxisTitle.Text = "time (sec)";
        Horiaxis.HasMinorGridlines = true;

        Horiaxis.LogBase = 10;
        Horiaxis.MinimumScale = 1;
        Horiaxis.MaximumScale = 1000;
        Horiaxis.TickLabelPosition =     Microsoft.Office.Interop.Word.XlTickLabelPosition.xlTickLabelPositionLow;
}

I want to achieve the same purpose, using NPOI library. I did go through a few threads, but could not find a relevant solution to my problem. Can anyone help me write equivalent code for this using NPOI library?
