Horizontal axis of chart inside pdf file is scaled wrong and reversed.

Here is example:

var workbook = new Workbook();

Worksheet worksheet = workbook.Worksheets[0];

worksheet.Cells["K1"].PutValue(10);
worksheet.Cells["K2"].PutValue(50);
worksheet.Cells["K3"].PutValue(100);
worksheet.Cells["K4"].PutValue(200);
worksheet.Cells["K5"].PutValue(400);
worksheet.Cells["K6"].PutValue(1000);
worksheet.Cells["K7"].PutValue(2000);
worksheet.Cells["K8"].PutValue(3000);
worksheet.Cells["K9"].PutValue(5000);
worksheet.Cells["K10"].PutValue(6000);
worksheet.Cells["K11"].PutValue(7000);
worksheet.Cells["K12"].PutValue(8000);
worksheet.Cells["K13"].PutValue(9000);
worksheet.Cells["K14"].PutValue(10000);

worksheet.Cells["L1"].PutValue(10.1);
worksheet.Cells["L2"].PutValue(24.2);
worksheet.Cells["L3"].PutValue(31.3);
worksheet.Cells["L4"].PutValue(46.2);
worksheet.Cells["L5"].PutValue(59.2);
worksheet.Cells["L6"].PutValue(82.3);
worksheet.Cells["L7"].PutValue(87.2);
worksheet.Cells["L8"].PutValue(91.1);
worksheet.Cells["L9"].PutValue(94.2);
worksheet.Cells["L10"].PutValue(94.9);
worksheet.Cells["L11"].PutValue(95.4);
worksheet.Cells["L12"].PutValue(95.8);
worksheet.Cells["L13"].PutValue(96.1);
worksheet.Cells["L14"].PutValue(96.4);

int chartIndex = worksheet.Charts.Add(Aspose.Cells.Charts.ChartType.ScatterConnectedByCurvesWithDataMarker, 0, 0, 20, 7);

Aspose.Cells.Charts.Chart chart = worksheet.Charts[chartIndex];

chart.PlotVisibleCells = false;

int index = chart.NSeries.Add("L1:L13", true);
chart.NSeries[index].XValues = "K1:K13";


var pdfSaveOption = new PdfSaveOptions()
{
AllColumnsInOnePagePerSheet = true
};


workbook.Save("test.pdf", pdfSaveOption);
Process.Start("test.pdf");
