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 describes the average shifts in the proportion of prices of three different metals, including Copper, Nickel, and Zinc. The main facts that stand out are the downward movements of metal prices during the twelve months of 2014.
At the beginning of 2014, starting with the highest point of 6 per cent, the price of Nickel sharply fell to 1 per cent in March but then experienced a wide oscillation between April and November, which was followed by the stability of the price, at 1 per cent. Unlike the metal mentioned above, the first two months witnessed a relatively rapid rise in the price of Zinc, and by March the figure had quickly dropped by 2 per cent. Next, there was also a wide fluctuation in the price between May and November, and then the percentage slightly rose to 2 per cent in December.
Concerning the other metal, starting with 2 per cent in January, Copper had dropped and grew over the first seven months; however, it remained unchanged, at 1 per cent, for the next three months before increasing a bit to nearly 2 per cent at the end of the year.
