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 how the prices of three metals (Copper, Nickel and Zinc) changed every month during 2014.
Firstly, in January, Nickel had the highest price, while Copper and Zinc were 4 and 5 percent lower. Then, while Nickel prices fell by 2% in February and 5% in March, Zinc prices increased by 2% in February but again fell in March. All metals reached their lowest point in June – the price of Nickel significantly fell by 9% from January, and Copper and Zinck prices gradually decreased by 2.5% and 2% by that time.
After June, prices of all metals started to increase. The price of Nickel increased by 2% in July and was stable for 3 months. It fell again in October but rose again in November. The prices of Zinс and Copper had the same changes, although Copper prices were much higher than prices of other metals at that time. Finally, in the end of a year Zinc price was higher than in the beginning, whereas prices of Copper and Nickel in December were lower than in January.
