Ok, it looks that it is working now, I’ve used below code:

List<ExternalRelationship> references = chartPart.ExternalRelationships.ToList();
            for (int i = chartPart.ExternalRelationships.Count() - 1; i >= 0; i--)
            {
                ReferenceRelationship refer = chartPart.ExternalRelationships.ElementAt(i);
                chartPart.DeleteReferenceRelationship(refer);
            }
            chartPart.ChartSpace.RemoveAllChildren<ExternalData>();

            string relationID = "rId99999";
            EmbeddedPackagePart embeddedPackagePart1 = chartPart.AddNewPart<EmbeddedPackagePart>("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", relationID);
            memoryStream.Seek(0, SeekOrigin.Begin);

            embeddedPackagePart1.FeedData(memoryStream);

            chartPart.CreateRelationshipToPart(embeddedPackagePart1, relationID);
            ExternalData externalData1 = new ExternalData() { Id = relationID };
            AutoUpdate autoUpdate1 = new AutoUpdate() { Val = false };
            externalData1.Append(autoUpdate1);
            chartPart.ChartSpace.Append(externalData1);

My workbook is now working properly.

I know how to update data in embedded workbooks, how to do it in external workbooks, but unfortunately I have to embed/attache one to the chart.

I managed to attach file into presentation package, unfortunately its name is “package.bin” (but when I unzip it then it looks ok), and I still do not know how to set appropriate relations. I have to also delete the old relations to external/embedded workbooks, if they exists.

I am using below code to attache workbook into presentation package:

            EmbeddedPackagePart embeddedObjectPart =chartPart.AddEmbeddedPackagePart(@"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");

            embeddedObjectPart.FeedData(File.Open(tempDirectory + "\\sos.xlsx", FileMode.Open,FileAccess.ReadWrite));
