If your best resolution data is "per day", then no - there simply is not the data to graph at a higher resolution. RRD only stores the data you ask it to plus a few internal values used to calculate it. If you want to plot/extract data for a higher resolution, then you'll have to alter your database to hold the extra data, and possibly modify your collection routines to make sure it's populated in a timely manner. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
