An ergograph is a graph that shows a relation between human activities, or agricultural/climate factors, and a seasonal year. The name was coined by Dr. Arthur Geddes of the University of Edinburgh. It can either be a polar coördinate (circular) or a cartesian coördinate (rectangular) graph, and either a line graph or a bar graph.
