1. A system for evaluating a blood vessel of a patient, comprising:
a first instrument sized and shaped for introduction into the blood vessel of the patient; and
a processing system configured for communication with the first instrument and a second instrument, wherein the processing system configured to:
obtain pressure measurements from the first and second instruments while the first instrument is moved longitudinally through the blood vessel from a first position to a second position and the second instrument remains stationary;
output, on a display in communication with the processing system, a graph comprising a plurality of bars associated with a pressure ratio of the obtained pressure measurements along the blood vessel; and
modify, in the graph, at least one bar of the plurality of bars to simulate an anticipated effect of a proposed treatment option.
