MRTG lets you graph 2 OIDs in the same graph or in the same target
command line. I have not found how to graph more than 2. My current
issue is that I need to graph 4 OIDs in the same graph. I have search
all the documentation with no luck. Using math functions I've seeing
how people can get information from several OIDs and get the result
but I'm still assuming the final graph is 2 lines.

I this is my target line but it is not showing 4

Target[device]: .1.3.6.1.4.1.2334.2.1.4.2.1.5.404&.
1.3.6.1.4.1.2334.2.1.4.2.1.5.405:public@device and .
1.3.6.1.4.1.2334.2.1.3.2.1.24.405&.
1.3.6.1.4.1.2334.2.1.3.2.1.25.405:public@device

Any help is greatly appreciated
