While Converting PPTX to PDF in Java, Charts Are Not Rendered Properly

@forasposeissues,
Please note that on slide 9, the X-axis value labels are rotated in your screenshot, but the labels are not rotated in my PowerPoint desktop version and Office 365.

Could you please make sure that you are using the same presentation file you shared earlier?

I checked the slide no. 9, it is the same presentation file I was using earlier, the labels are rotated on X-axis.
Attaching the presentation file for your reference.

@forasposeissues,

Could you please specify the name and version of the application that you used to view the presentation?

The name and version of Application I am using is :
Microsoft PowerPoint (Microsoft 365 Apps for enterprise), Version 2502.

@forasposeissues,
Thank you for the details. Perhaps different versions of PowerPoint display the chart differently. On my end, PowerPoint (desktop version and online version) displays the chart axis labels without rotation on slide 9, and both PowerPoint and Aspose.Slides convert the chart without label rotation.

Regarding the blue lines that appear on page 25 of the output PDF document, I have reproduced the problem. We have opened the following new ticket(s) in our internal issue tracking system and will deliver their fixes according to the terms mentioned in Free Support Policies.

Thank you,

For the issue in slide 9 is not about rotation, the x-axis labels are intersecting with the text below it when converted to pdf.
While in ppt document there is sufficient gap between the labels and the text below the labels.
Attaching the document with the issue is slide 9, I have highlighted the intersected portion in pdf screenshot.

Could you please give update on last point regarding slide 9 in which the labels are intersecting with the text below it on X-Axis?
So that we can raise it from premium account.

@forasposeissues,
I have found that the issue is related to the Citi Sans Text font. Could you please share the font?
