I think I saw screenshot somewhere but I cant find it anywhere under web interface.
I am aware of a CPU load graph under status --> realtime graphs.
If you are on the eligius pool, you do get realtime hashrate and earnings graphs on his site.
E.g., http://eligius.st/~wizkid057/newstats/userstats.php/146J6Eqsu9ZDFq8VqzXPehYQdYHQZUUuuB
There is a WiFi real time graph, and it gives signal, noise, and SNR. On one machine it works, on the other it is not reporting anything. I thought I had set them up the very same way. Does anyone know a toggle for this graph?
