Good idea - but it's not working for me right now. After the queries are imported the count of 'Total queries' jumps up from 0 to a few thousand but no charts are updated. After a while the top lists are updated/populated but the 'overTime' graphs are not (or I did not wait long enough)

[DL6ER]

The update should work immediately so not having waited long enough isn't an option. I looked again at the logic and you description of

the count of 'Total queries' jumps up from 0 to a few thousand

translates into

if (0 < 1000 && 1000 > 100) {
  // update the charts
}

should definitely have fired. Either this is a caching issue with the JS file or - I'm afraid - I have to ask you to do some debugging on this when time allows.

Ok, you have probably be right with the caching issue. I tried with a fresh cache on FF and Chrome and it worked better - but now I get a constant re-drawing. I think we miss an exit of the loop somewhere.
