I presume you mean to display a frequency vs. signal strength graph...
the answer is yes -- they are called panoramic adaptors or
panadaptors. A more general device would be a spectrum analyzer, used
as a panadaptor.

You can expect to pay about $1500 for a new one, and at least one is
being made today. I bought one for about $100 and was only marginally
satisfied. I bought a spectrum analyzer for $300 that does a much
better job.
