The provided graph illustrates the consumption patterns of three varieties of jam in an Asian nation over the period from 1991 to 2014.
Overall, the data indicates significant fluctuations in the consumption levels of these jam types, with strawberry jam experiencing a steady decline, while lemon jam consumption remained relatively stable. In contrast, cherry jam witnessed an introduction phase followed by growth and a subsequent decrease.
Strawberry jam consumption commenced at 80 tons in 1991 and exhibited a notable increase, achieving a peak of 160 tons in 1996. However, this was followed by a downturn, with consumption decreasing to 120 tons in 2001. The decline intensified sharply, as consumption plummeted to 40 tons in 2006, maintaining this low level until 2011. Ultimately, strawberry jam consumption fell to zero by 2014, indicating a complete cessation of its popularity.
Conversely, lemon jam maintained steady consumption of 40 tons from 1991 until 2001 and subsequently increased to 80 tons in 2006. This increase was short-lived, as consumption reverted back to 40 tons in both 2011 and 2014, suggesting minimal change over the later years. Meanwhile, cherry jam, which was not consumed prior to 2001, saw a rapid ascension, starting at over 40 tons in 2006, reaching a peak of just below 80 tons in 2011, before experiencing a decline to 20 tons by 2014.
