cumulative record

a continuous tally or graph to which new data are added. In conditioning, for example, a cumulative record is a graph showing the cumulative number of responses over a continuous period of time. It is often used in such contexts to display performance of free-operant behavior under a schedule of reinforcement and provides a direct and continuous indicator of the rate of response.
