Mean protein content of western Canadian peas (green and yellow combined)

Graph of peas protein content, 2002 to 2013 and 10-year mean. Details below.
The graph depicts the annual average protein content of all peas from 2002 through 2013, and the 10-year (2003-2012) average. Each point represents the average protein content of peas in that crop year. A solid line connects the points, showing the variation of the average protein contents from 2002 through 2013. The dashed line represents the mean protein content of peas (23.6%) over a 10-year period from 2003 to 2012. Average protein contents from 2003, 2006, 2007 and 2010 (24.3%, 24.5%, 24.7% and 23.9%, respectively) were all above the 10-year average of 23.6%, while those from 2004, 2005, 2008, 2009, 2011, 2012, and 2013 (23.0%, 23.5%, 23.2%, 22.4%, 22.6%, 23.5% and 22.0%, respectively) were below the 10-year average.
