AP Grapher is a freeware program for Mac OS X which searches for and
displays nearby wireless (AirPort/WiFi) access points along with
information about their percent availability, maximum signal strength,
and last contact time. The grapher window allows you to graph multiple
signal strength parameters for the base station you are currently
connected to and optionally display them in the dock icon. Many user
configurable preferences allow you to customize its behavior including
refresh rate and optional display in the dock icon or menu extra.
