Exporting charts to pdf is cluttered and incompatible


Hello, I made an excel from Predefined Excel Template and it contains a chart, I used " application.ChartToImageConverter = new Syncfusion.ExcelChartToImageConverter.ChartToImageConverter();" to accommodate export excel to pdf with existing charts. But when I export it to PDF, the chart is messy and looks truncated (the labels that are displayed are lacking) and the text has shifted from the specified table. even though in Excel there is no weirdness like in the picture on the right above.

iam using this code to export chart to pdf :

//Instantiating the ChartToImageConverter and assigning the ChartToImageConverter instance of XlsIO application

application.ChartToImageConverter = new Syncfusion.ExcelChartToImageConverter.ChartToImageConverter();

//Tuning chart image quality

application.ChartToImageConverter.ScalingMode = ScalingMode.Best;

ExcelToPdfConverter converter = new ExcelToPdfConverter(workbook);

                        //Initialize PDF document

                        Syncfusion.Pdf.PdfDocument pdfDocument = new Syncfusion.Pdf.PdfDocument();

                        ExcelToPdfConverterSettings settings = new ExcelToPdfConverterSettings();

                        //settings.LayoutOptions = LayoutOptions.FitAllColumnsOnOnePage;

                        //Convert Excel document into PDF document

                        pdfDocument = converter.Convert(settings);

//Save the PDF file

                        string fileNamePDF = resultHeader.Name + "-" + resultHeader.Submitter + "-" + resultHeader.Process + "-" + resultHeader.MachineNo + "-" + resultHeader.Equipment + "-" + resultHeader.Classification + "-" + resultHeader.PlanDate + "-" + ".pdf";

                        //pdfDocument.Save(fileNamePDF, HttpContext.ApplicationInstance.Response, HttpReadType.Save);


                        //Saving the Excel to the MemoryStream

                        MemoryStream streamPDF = new MemoryStream();


                        //Close the document


                        if (streamPDF.CanSeek)

                            streamPDF.Position = 0;

                        fileStreamResult = new FileStreamResult(streamPDF, "application/pdf");

                        fileStreamResult.FileDownloadName = fileNamePDF;

with return type FileStreamResult

Muhammad, Thanks for sharing the requested details.

As of now, Syncfusion XlsIO do not have support for multi-level category axis in Excel to PDF conversion. We have logged a feature report for this but do not have any immediate plans to implement this. You can track the status of this feature report through below feedback link.


Regarding the issue in table, we are able to reproduce it and validating it currently. We will share the validation details on March 8th, 2023.

Muhammed, we have confirmed the issue as Category labels are incorrect when multi level labels are applied in the chart and logged a defect report. We will include the fix for this issue in our weekly NuGet release scheduled for March 21st, 2023.

We are unable to move the fix in this Weekly NuGet due to complexity. We will include this fix in our next weekly NuGet release scheduled for April first week, and let you know once the package is available to download from nuget.org.

Muhammed, we have included the fix for the issue Category labels are incorrect when multi level labels are applied in the chart in our weekly NuGet release version 21.1.38. Kindly upgrade your packages to this new version and let us know if the reported issue is resolved.

Latest NuGet Package: https://www.nuget.org/packages/Syncfusion.ExcelChartToImageConverter.AspNet.Mvc5/21.1.38 

But, we have an issue in alignment and validating this. We will share the details for this on March 6th, 2023.

KK Konduru Keerthi Konduru Ravichandra Raju Syncfusion Team April 6, 2023 01:32 PM UTC

Muhammed, on validating, we found that the issue in alignment is due to default system DPI-aware of WPF application. 


Please go through the below article, where different ways to avoid such DPI changes are documented.



Kindly try these to overcome the DPI issue.
