The given graph illustrates a company’s unit sales of 5 different types of jam from 2009 to 2014.
In general, the unit sales of plum underwent a downward trend, which was not true for the other counterparts. Noticeably, the figure for cherry saw the most significant fluctuations throughout the period.
The unit sales of strawberry, raspberry and grape rose sharply throughout the period. Strawberry was the most sold jam, accounting for the highest figure of 3.5 million in 2009, followed by that of raspberry at nearly 3 million. After a gradual increase to approximately 4.5 million in 2010, the unit sales of strawberry surged to 5.5 million in 2011 before resuming its initially steady trajectory, culminating in a figure of 6.3 million. Meanwhile, the unit sales of raspberry underwent a consistently slower growth, lagging behind that of strawberry throughout the period and ending at 5.1 million. Having climbed slightly to 2 million in the middle of the year 2011, the unit sales of grape embarked on a sustained phase of considerable growth, quickly narrowing its gap with other counterparts.
The unit sales of cherry and plum converged at 2.2 million in 2010 after the former inched down from its initial figure of approximately 2.4 million and the latter edged up from 1.7 million. The gap between them began to widen towards the end of the timeframe when the remainder of the period witnessed an intermittent climb to 2.5 million in the unit sales of cherry and a trough of nearly 0 million in that of plum.
