The graph shows wheat exports of three different areas, which are Australia, Canada, and European Community, from 1985 to 1990. During the selected years, the volume of the exports of all three areas fluctuated between 10 millions of tonnes and 25. Overall, it would appear from the graph that there is an inverse correlation between Australia and European Community.
The most fluctuating area is Canada, with a high of 25 millions of tonnes and a low of 14. Canadian exportation's volume fell slightly in 1986 and then quickly recovered. The figure went further until the peak of 25 millions in 1988. After a rapid increase, the figure declined to 19, hitting a rock bottom of 14 millions in 1989.
For Australia and European Community, a negative relationship is seen from the beginning to the end. European Community's wheat exports fell slightly in 1986 and then started increasing slowly but surely until 1990 whereas Australia is the exactly other way round. Its exportation volume declined gradually until 1989 and then levelled off.
