improving the graphs

[Jeff Weisberg]

|     Can we change the time scale? and in next versions change the "y" and 
| time range dynamicly? Some times is useful to watch in details some graph 
| section...
|    May be you can send us how graph data is storage, and then each one can 
| made a customized graph...It is posible?



I was about to reply telling you the parameters you can set
to change the time range, but then I checked. the code is there,
but you cannot actually configure the values. I'll fix that.
soon, you'll be able to say:

	gr_xrange_samples:	30hours
	gr_xrange_hours:	4weeks
	gr_xrange_days:		1year


oh, I've also recently added code so that things like '30hours'
will work for most things that take a time duration. such as
	frequency:  5min
	retrydelay: 45sec


as far as the y axis, if you do not like the range that
gets dynamically selected, you can override it with:
	gr_range: 0-1000
