Looking for a Data -> Graph Tutorial

[Shish]

While it seems cacti is so much easier for graphing things it has templates for, creating templates is horribly painful :-/


Firstly, because it seems the simpler -- I have a single OID reporting a single value; how do I graph it against time for a given host? (In this case, users connected to a wireless access point)


Secondly -- I know a set of OIDs, which I can snmpwalk. Walking one gets names, walking another gets maximums, walking another gets current values. How can I take these three OIDs, and end up with a set of graphs with a title (the name) and two values (current and maximum)?

The reported value is how much is being used, I want to graph how much I have left. How can that be done?

How can I get all the values for a host on a single graph? (ie, the graph is how much I have left against time, with several lines for several sources)

For specific reference, this is ink levels on an HP printer -- the templates someone else on the forum made are for a newer version (debian stable is on 0.8.6c, they have 0.8.6g). Also, I'd rather know how to make templates properly than fiddle with someone elses and pray it doesn't go wrong (since I'll have no idea how to fix it)
