A method of evaluating an interaction parameter for the interaction between a plurality of analytes and a ligand using a biosensor, which comprises the steps of: A: providing a sensor surface having the ligand immobilized thereto, B: contacting the sensor surface with the plurality of analytes, C: registering a sensor response curve for each one of the plurality of analytes, D: extracting interaction parameters from each sensor response curve, E: evaluating each sensor response curve according to one or more binding behavior criteria, F: displaying the interaction parameters in a diagram, wherein interaction parameters relating to response curves meeting a binding behavior criteria are graphically distinguishable from interaction parameters relating to response curves meeting another or no binding behavior criteria.
