Span & timepicker

Hi All,

I would like to give the users an option/control for span in a pull-down based on the value of the time-range picker. This is to prevent the users from using 5min window on 30 day search as the results get truncated in time-charts.

Any Ideas ???

Last 24 hours -> span=5min

Last 7days    -> span=1hr

Last 30days   -> span=1day

etc etc etc

Thanks for your help

Regards

KK
