I am assuming that VisualRF would attempt to plot the location of the access point based on the "Discovery Events" portion of the Rogue AP screen. That would require 3 or more access points being able to see the "Rogue" AP for that to be able to happen. I would not expect any accurate results in terms of location due to the fact that a number of access points would need to see that AP within a certain time frame for Visual RF to guess the location, because unless access points are serving clients on the same channel as the rogue access point, it would not scan that channel often.
With that being said, look at the "discovery events" portion of the rogue AP section to get an idea of what access point saw the AP at what time. Due to the great receive sensitivity of Aruba APs, you will see quite a few access points that are not even in the building... You might want to use a handheld device to track down access points whose signal strength is very good.
