We're attempting to generate PDF reports from one of our dashboards. The dashboard is laid out like:
| Section 1 - double width |
| Section 2 || Section 3 |
| Section 4 || Section 5 |
| Section 6 - double width |
All of these charts get chopped off at the right-hand side, no matter what paper size and orientation we choose (although if we use A2 they all at least fit on the one page).
And the bottom graph never contains any data, although there's definitely data in the dashboard.
Now maybe we're doing something wrong, but judging from the amount of unanswered questions I've come across regarding PDF support in Splunk, I'm starting to think that it simply doesn't work very well.
I have in certain cases used A0 before in order to fit all the panels in. It would depends on your actual usage for the PDF reports, but for my case it was actually for historical/archival purposes and at no times are we going to print a A0 page out.
I don't think it will help you in this particular case, since you're already experimenting with page orientations. (BTW, did you really mean A2, not A4? Yikes!) But who knows, maybe you'll run into another issue that it can help with.
