In PDF output of excel chart- labels are overlapping and lines in the chart are missing


I am using Aspose.Cells v17.4.0 to generate PDF of chart - "Chart 1" in the attached excel file. In the PDF output, some of the chart labels are overlapping and lines pointing to the labels are missing.

Following code is used to generate the output:

Workbook workbook = new Workbook("test.xlsx");
WorksheetCollection ws = workbook.getWorksheets();
String worksheetName = "College Budget";
Chart chart = ws.get(worksheetName).getCharts().get("Chart 1");
chart.toPdf("D:\\aspose generated 17.4.0.pdf");

Can you please analyse this issue.

Is there any update on this issue?



I am afraid, there is no update on your issue (logged earlier as “CELLSJAVA-42279”). Such issues are difficult to resolve accurately as MS Excel itself shows an inconsistent behavior when rendering leader lines to the labels. There may not be any definite and compact rule to be followed. Anyways, I have logged your concerns against your issue into our database and asked the concerned developer to update on it or provide an ETA (if possible).

Once we have any new information, we will let you know here immediately.

Thank you.


Thanks for using Aspose.Cells.

We are afraid, your issue is too complex for us. Because, in Excel file, there is no information of position of DataLabels that are automatic. This is the reason, we can’t find a solution to place the DataLabels to best location.
