Two devices, one graph?

Have what could be a simple question. When monitoring an SNMP device w/MRTG,
is it possible to plot the data from two devices on a single graph?

 

I have two temperature probes. I would like probe #1 (indoor temp) displayed
as the I value and probe #2 (outdoor temperature) as the O value.

 

Currently I am monitoring the indoor temp with the noo option enabled.

Target[ncr-temp]:
1.3.6.1.4.1.3854.1.2.2.1.16.1.3.0&1.3.6.1.4.1.3854.1.2.2.1.16.1.8.0:public@1
0.44.1.60

 

I also have a second temp probe (also noo option) on a different IP address
measuring outdoor temperature.

Target[outdoor-temp]:
1.3.6.1.4.1.3854.1.2.2.1.16.1.3.0&1.3.6.1.4.1.3854.1.2.2.1.16.1.8.0:public@1
0.1.1.60

 

Would love to modify the syntax of the Target line in the cfg file to
support polling the I & O values from different devices.

Something like below, but this doesn't seem to work.

 

1.3.6.1.4.1.3854.1.2.2.1.16.1.3.0:[email protected]&1.3.6.1.4.1.3854.1.2.2.1
.16.1.3.0:[email protected]

 

 

Thank you, in advance, for any assistance. I have search the forums and
found that others have asked the same fundamental, however the links to the
solutions are dead links.
