Hit the export button and change the following settings:
Paper format: legal
orientation: landscape
Export!
Look at the PDF
All the bars are missing! And the gantt chart is still in portrait, and it does not fill the entire page (see attached PDF)
I almost lost my mind on this one. Our export server works fine on my dev machine, but has the same problem as yours on our production environment. This has started after doing an upgrade from 5.2.7 to 5.6.2. REALLY weird. Good luck
Hello.
Which version of PDF export server do you use? More specifically, which puppeteer version? I get a feeling because of outdated browser some styles work different, or maybe even not supported. It has to be a problem with a browser version, because styles are apparently loaded.
Another possible source of a problem is wrong CSS. If you're hosting CSS from PDF server itself (using -r option), then you need to make sure that CSS is updated properly along with Bryntum package upgrade.
Speaking of wrong page orientation, this is expected. Page itself is in landscape mode, but in order to fit gantt entirely on one page content got scaled proportionally. Gantt itself looks portrait because in our demo its height exceeds its width. I can suggest using multipage vertical exporter.
I use pyppeteer, which is puppeteer for Python. It uses Chromium 71.0.3542.0 by default. It is quite old indeed... And so is pyppeteer at this point. I could force a later revision of chromium, but the doc warns this could break pyppeteer.
I made sure the correct CSS was loaded.
I made a mistake in my original post. I thought I had forced the export server on my dev machine to use the same chromium version as on our production server but I hadn't. It was using an up to date google-chrome instead. So that's why it was working. I managed to force the same version of chromium and I got the same result as on our production server. It finally makes sens...
Do I understand correctly that hypothesis about outdated browser is true on your end, and you solved problem by upgrading? We upgraded our version to 104.0.5109.0 but it didn't help. However, that is still 15 major versions behind.
Yes it is true on my end. If I force pyppeteer to use my OS google-chrome version 119.0.6045.199, the diagram is fully shown.
So, I just proceeded to find the exact revision of chromium where the rendering broke. Here's what I found:

So the rendering is broken for revisions 701143 and older.
Revision 701156 is version 79.0.3929.0
Revision 701143 is also version 79.0.3929.0.
I just realized you still have the problem on version 104.0.5109.0 which is way more up to date. Now I'm having a hard time finding that version in the snapshots repository. Still looking...
Revision 1015884 is version 105.0.5132.0
Revision 896293 is version 93.0.4555.0
Here's an updated list of revisions, results and versions. I'm fairly confident 104.0.5109.0 is fine on my side.
