Graphing limit question.

Is there someway to tell the graph to user lower-limit.

Something like

From http//people.ee.ethz.ch/~oetiker/webtools/rrdtool/doc/rrdgraph.en.html
[code1672f6e164b]
Limits
[-u|--upper-limit value] [-l|--lower-limit value] [-r|--rigid]

By default the graph will be autoscaling so that it will adjust the y-axis to the range of the data. You can change this behaviour by explicitly setting the limits. The displayed y-axis will then range at least from lower-limit to upper-limit. Autoscaling will still permit those boundaries to be stretched unless the rigid option is set.

Perhaps I have misunderstood something )

Currently we only allow our graphs to auto-scale. We can have some 'upper limit' type functionality by adding a "maximum" line to a graph; but this only works if the data stays below the maximum line.
If you click on an individual graph, there is an "advanced" link available near the bottom which you can use to change the period over which you're viewing the graph, and the upper and lower limits. This is currently only viewable on an individual graph at a time right now.

Oki, thanks for the fast answer.

Actually, we do have a feature to do this. If you edit the graph, there is a "Show Advanced" at the bottom of that page as well that allows you to set persistent mins and maxes for a graph, among other things.

It honestly isn't a feature that Doug or I use that often, hence we both forgot it was there wink (I only remembered while working on an issue this evening that involves this feature).

Aye, great!

I tried to fiddle with that one before, but entered 0 as the min value.
But then it goes back to unlimited.

So now I can do a 1 or -1 value there )

Thanks again for a great piece of software..

Yes, someone did file a bug report for that issue. It will be fixed in the next release.
