About the parameters that can be used in URL:
- I didn’t notice any change with ‘&fullscreen’. Where did you get it?
- you can specify ‘width=…’ and ‘height=…’ (in pixels), it may solve your problem
- I’m not sure you can give time range without epoch
- there is also ‘&autofitpanels’ that can be useful
Currently I’m using https://HOSTNAME/render/d/uid/Dashboard_name, I don’t see any difference with your URL except that I have to specify the dashboard UID.
FYI, I’m trying to add support for PDF format with a few changes in grafana-image-renderer and grafana.
