[rrd-users] How to Force Generation of VRULE Regardless of Scale

I have had a different experience. I keep four MTG-like graphs (i.e., 24 
hours, 7 days, 1 month, 1 year) and occasionally I add a VRULE. That VRULE 
will appear on each graph (recall: varying time periods) at the specified 
time, with the same pixel width.
