Thanks for the template file and sample code with details.
After an initial test, I observed the issue as you mentioned by using the following sample code with your template file. I found that Aspose.Cells recognizes fonts in the chart incorrectly. The font in the title of second value axis is recognized as “Arial Narrow” in bold but in fact in the original Excel file it is “MS PGothic” in regular weight:
e.g Sample code: var
chart = workbook.Worksheets.Charts;<o:p></o:p>
// Print "出来高 (1,000株)"
// Print True (Supposed to be false)
// Print “Arial Narrow” (supposed to be MS
I have logged a ticket with an id “CELLSNET-45397” for your issue. We will look into it soon.
Once we have an update on it, we will let you know here.
