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.

A screenshot is also helpful when reporting rendering issues.

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

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.

I think fonts look are improved since my bug report, and maybe they are not perfect, however more readable now. I'm not sure if this should be a subject of your workload, if nobody else didn't cacth a notice :/ Maybe if you really had nothing else to ammend.. but in such case I will have to agree it has been fixed.
Thank you for your time.

"Fixed" is when we know the commit, here would be WorksForMe.
But if you can, it would be nice to attach source .ODS with the example.
