This line graph depicts the average fluctuation in prices of three kinds of meal each month over the year of 2014.
To a large extent, the proportions of copper and zinc stay constant, while nickel decreased massively to the lowest. Nickel held the highest level of all three meals at the start , then decreased to the lowest level for the rest of the period given. Likewise, zinc took over the highest place, followed by copper at the end of 2014.
Two percent is illustrated as the amount of change for copper at the start, eventually declined to minus one point five percent, before rose nearly to its former point. Likewise, zinc started at one percent, following the decrease to mines one percent on June, keeping a steady level before inclined to one point five at the end of the period.
