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.

It is worth noting that from march to May all costs were constantly decreasing, furthermore, in July, August, and September values were unchanged at all. In December three figures turned out to be approximately similar in the range from 1% (nickel), to 1,5% (copper), and to 2% (zinc).
