Cheshire Cat Computing

Hi, I been requested to create a graph that run at 30 second samples (this is because it is recording VoIP data and they want to see the max number of simultaneous calls (multiples of 100k) and by the nature of Voip a lot of these calls can be very short):

i Have this working however my x axis is now giving the wrong times. (ie approx half hour is represented as an hour) is there any tricks to get around this?

I do appologise if this is covered else where - i did hunt around but couldn't see it.

Many Thanks

Rob

ahh ignore me - this seems to have fixed itself after a few hours and the x scale has gone to what i would expect. strange.
