Diagram is not shown in html when sheet has no other content - Excel to HTML


We are converting xlsx to html using the following code and Aspose.Cells 20.9.0:

var options = new HtmlSaveOptions
    ExportImagesAsBase64 = true,
    ExportSingleTab = true,
    ExportGridLines = true
using (var wb = new Workbook("..."))
    wb.Save("...", options);

On converting the noOtherContent.xlsx file from the archive below, the diagram is not shown. If there was some other content on the sheet (added “test” into cell A1 in withOtherContent.xlsx), the diagram would be shown as expected (see images below).
noOtherContent.PNG (1.0 KB)
withOtherContent.PNG (10.9 KB)

This issue was not present in 20.8.0.
files.zip (30.0 KB)
