Description marcin_mail2005 2018-05-17 09:03:39 UTC
When I create chart, especially with plenty of data, X-axis (but Y-axix probably, too) font look ugly, when rotated (rotated = everything else than 0 degree).
Probably font is not being smoothed, it's pixellated only.

Steps to Reproduce:
1.Open up the Calc
2.Create table with data
3.Create chart
4.If X-axis labels are not present = add X-axis labels.
5.Rotate x-axis labels
6.See pixellization.

Actual Results:  
Pixellization present makes chart labels unreadable in most cases (when there's plenty of data, for example).

Expected Results:
Add smoothing function (add standard TTF font usage).

Reproducible: Always

User Profile Reset: Yes

OpenGL enabled: Yes

Additional Info:
It's not just cometical bug, because if X-axis labels is date, so it's impossible to know the timeline, for example.

Reproducable with LibreOffice 6.0.4 (Windows 10)- OpenGL enabled
No problem with OpenGL disabled.

Dear marcin_mail2005,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)

If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from http://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword

Thank you for submitting bug with repro steps. But please attach a sample document with chart. Preferably you may include text or image in that document to indicate what's not as expected. Please understand that we review and check a large number of bugs, so that's easier for us.
