The provided line graph illustrates the variations in the turnover of five distinct kinds of jam, measured in million units, spanning from 2009 to 2014.
Overall, it is evident that all of the surveyed jam demonstrated an upward trend in sales except for that of plum which indicated a reverse pattern. Notably, the avenue from strawberry jam maintained its dominant position throughout the entire period.
In 2009, strawberry jam received over 3 units from sales, increasing steadily to a point of 5 in the next three years and establishing itself as having the highest turnover at its peak of 7 in 2014. Likewise, this is followed by that of raspberry which started at approximately 2,8 and moderately ascended to over 5, surpassing the avenue of strawberry jam in 2012, before rising to a lesser extent and finished at around 5,7. A noteworthy observation can be seen in grape jam, whose figure was the lowest among all productions, at 0,5, prior to a rocket to about 4,5 during the time frame.
With regard to the remaining types, jam made from cherry underwent a noticeable fluctuation in sales, beginning at around 1,8 and then rising to roughly 2,5 before a gradual decline by 0,5 units and eventually hovering at under 3 by the end. Moreover, the turnover for plum jam was initially recorded as achieving the identical figure as that of raspberry, but it plummeted to almost nothing after a 5-year period.
