Refine Area To Determine PV Work in Heat Engine Cycle (Capstone)

How do I refine an area for a PV graph to determine the work by a thermodynamic cycle? When collecting data for pressure and volume for a heat engine, it can be difficult to get the heat cycle to close completely. To help with this process, you can use the playback mode within the display to move the graph to where the cycle just closes. This can help determine a much more accurate area for the heat engine cycle and the work that is performed.
