I've had a couple of BQMs running for a while now, but if I click "XML data" for them, I get a 404. Is this a known thing, or do I have an incorrect assumption/expectation?
You can only get the daily xml data for "completed" graphs, ie yesterday and before. If you want the "live" data, ie for today, you'll have to wait until tomorrow. (I don't know how long you have to wait after midnight before it's available.)
Ideally, I think the option to download xml data shouldn't be there if you're viewing a live graph, but Seb & co probably have more important things to do...
