BQM graph not showing

I do not have any graphs showing before 20th June. I haven't changed anything, is there a reason for this or have I missed something?

Same here.

There's quite a lot of them on the server and they probably take up a fair bit of space, so I'd guess Seb has archived the older ones off somewhere. If you really need one, and can identify it, he could probably winkle it out.

Yes I should think there are. I was trying to find one from my previous router (changed 12/6) to compare. My new router is full of yellow lines and red bits, top and bottom of the graph which wasn’t the case with the old one.

Same and there has always been a limit on how far back results are kept.
