Confirming both parts of Michael's response.
VisualRF has no current knowledge of AP height. And orientation is only for external antennas. These are both items that should be added as feature requests in the ideas portal.
As for the location of your rogues, for a single AP, the placement is just going to be based on a single point of contact. All you will have is a depiction of distance from an AP in any general direction. Add a second AP, and then the clients between the 2 APs will have better clients than the clients outside the 2 APs.
-Now if you have 3 APs in a straight line, you will have a 50/50 shot that the placement is on either side of the line
-Putting the 3 APs in a triangular deployment, you will have better triangulation for clients that hear all 3 APs. Note that hearing an AP and not hearing an AP are both constraints used for calculation. So if one of the APs doesn't hear the client, then the client is placed further from that AP. Also, having multiple APs gives a better attenuation rate based on AP to AP communication.
