A system is presented including at least one sensor and a monitor in operable communication with the at least one sensor. The monitor is configured to display a plurality of graphs each representing a measured physiologic parameter versus time, the plurality of graphs configured to be aligned with respect to each other along a time axis. A marker moves along the time axis of each of the plurality of graphs in response to an input received from an input unit. The plurality of graphs are stacked with respect to each other in a vertical orientation and in a non-overlapping manner.
