This is what would typically be referred to as the 'Power-run' screen. The ramp rate is selected in the software, and the dyno electronics controls the acceleration rate of the engine, the software records the requested data and displays it graphically. The graph is auto scaling, runs can be hidden to aid comparisons, pan and zoom functions work as standard window features. A simple right click on the curves allows labels to be auto assigned, as can min and max values, line colour's, thickness etc. The mouse pointer also snaps to the nearest line, and displays the exact value at that point.
