The image presents a line graph depicting the average monthly change in prices of copper, nickel, and zinc for the year 2014, measured as percentage change in price compared to previous month. Copper starts at approximately -3.5% in January, peaks at approximately 5% in July, and ends at approximately 0% in December. Nickel starts at approximately -2% in January, peaks at approximately 6.5% in May, and ends at approximately -1.5% in December. Zinc starts at approximately -1.5% in January, peaks at approximately 3.5% in July, and ends at approximately -2% in December. Copper shows a consistent increase from January to July, followed by fluctuations and a decrease towards the end of the year. Nickel shows a sharp increase from April to May, followed by fluctuations with a general downward trend. Zinc shows moderate increases and decreases throughout the year with no clear overall trend. Each data point is marked by a symbol representing the respective metal, with a key provided at the bottom of the graph.

The line graph illustrates the average price changes of three different metals—copper, nickel, and zinc—from January to December 2014.
It is evident that nickel and zinc exhibited similar trends throughout most of the year, while copper experienced significant fluctuations during the same period.
Nickel began the year with the highest price change, reaching a peak of 6%. In contrast, zinc started with the lowest price change at only 1%. From February to June, both nickel and zinc displayed a downward trend, hitting their lowest points at -3% and -1%, respectively. They then began to recover slightly in July, with nickel at -1% and zinc at -0.5%, before remaining steady until September.
In October, both metals experienced moderate declines, dropping to -2% and -1%. However, in the following months, both metals saw a dramatic increase, except for nickel, which stabilized towards the end of the year.
Copper prices declined during the first five months of the year but then followed a steady trend in the subsequent months. In July, copper prices increased from -0.5% to 1%, remaining stable at this level. After that, there was a slight decline from September to November before prices reached just below 2% by December.
