If you are saying that you have embedded graphs (from the graphs module) and they are not populating, it may be that an issue I reported back in Feb 2017 remains unaddressed.
Your options are to either set all the feeds and dashboard to public so you don’t use an apikey, but your data will be available to anyone that has access to the network your emoncms is on. Or you can use “multigraphs” instead of “graphs”, this option has the added benefits of not only being more secure/private than the first option, but multigraphs also auto update so that the data displayed doesn’t grow stale due to a static timeline, unless this has been resolved now, the graph module doesn’t auto-update.
