Set color marker in LineWithDataMarkers chart using Aspose.Cells for .NET in C#

Hi all,
I’m using Chart LineWithDataMarkers and when I set color for Marker and save with excel 2003 format, it not working. But xlsx is working.

Here is my sample code:
Workbook book1 = new Aspose.Cells.Workbook();
book1.FileFormat = FileFormatType.Excel97To2003;

            Worksheet sheet1 = book1.Worksheets[0];

            sheet1.Cells[0, 0].Value = "X";
            sheet1.Cells[0, 1].Value = "Y";

            Random R = new Random();

            for (int i = 1; i < 21; i++)
            {
                sheet1.Cells[i, 0].Value = i;
                sheet1.Cells[i, 1].Value = Math.Round(R.NextDouble(), 1);
            }

            for (int i = 21; i < 41; i++)
            {
                sheet1.Cells[i, 0].Value = i - 20;
                sheet1.Cells[i, 1].Value = 0.8;// Math.Round(R.NextDouble(), 1);
            }


            for (int i = 41; i < 61; i++)
            {
                sheet1.Cells[i, 0].Value = i - 40;
                sheet1.Cells[i, 1].Value = 0.9;// Math.Round(R.NextDouble(), 1);
            }


            int idx = sheet1.Charts.Add(ChartType.LineWithDataMarkers, 1, 3, 20, 20);
            Chart chart = sheet1.Charts[idx];
            chart.Style = 3;
            chart.AutoScaling = true;
            chart.PlotArea.Area.ForegroundColor = Color.White;
            //chart.NSeries.IsColorVaried = true;

            //Set Properties of chart title
            chart.Title.Text = "PCS";
            chart.Type = ChartType.LineWithDataMarkers;

            //Set Properties of categoryaxis title
            chart.CategoryAxis.Title.Text = "Units";

            //Set Properties of nseries
            int s2_idx = chart.NSeries.Add("A22: A22", true);
            int s3_idx = chart.NSeries.Add("A42: A42", true);

            chart.NSeries.IsColorVaried = true;

            chart.NSeries[s2_idx].Area.Formatting = FormattingType.Custom;
            chart.NSeries[s2_idx].Marker.Area.ForegroundColor = Color.Yellow;
            chart.NSeries[s2_idx].Marker.Border.IsVisible = false;

            chart.NSeries[s2_idx].XValues = "A22: A41";
            chart.NSeries[s2_idx].Values = "B22: B41";

            chart.NSeries[s3_idx].Area.Formatting = FormattingType.Custom;
            chart.NSeries[s3_idx].Marker.Area.ForegroundColor = Color.Green;
            chart.NSeries[s3_idx].Marker.Border.IsVisible = false;

            chart.NSeries[s3_idx].XValues = "A42: A61";
            chart.NSeries[s3_idx].Values = "B42: B61";

            book1.Save(@"d:\outfile.xls");
