Ergograph and Its uses

Ergograph: 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 shown as rectangular graph, either a line graph or a bar graph.
This graph of the climate of Weymouth and the Isle of Portland over the cycle of the year is a cartesian form ergograph. In cartesian form, the X axis is marked for the months of the year, and the Y axis is marked with the scale(s) of the activity/activities. For example, in the erograph to the right, the Y axis is marked with both temperature and rainfall/sunshine scales.
