Ha! That’s weird, and I’ll look into why that happened (thanks!). Two quick things, though:
i) does/should Plotly not order line graphs by date anyway?
ii) what about the situation I mentioned in my second post, where every now and then (perhaps every 25th reload) it does render as expected, then, when I press refresh (without changing anything), it reverts to the weird formatting?
So, embarrassingly, I now can’t replicate it either. I genuinely spent about an hour with this problem yesterday, but it seems to have gone now, and I haven’t changed anything in the way mongodb was sorting the data. This makes me feel pretty stupid (which, fortunately, is something I’m used to)…
Anyway, I guess I can stop bothering you now. Thanks so much for your help, and have a great weekend!
