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 provided illustration of the line graph does delineate some information about the mean monthly change in the cost of three distinct metals, such as copper, nickel, and zinc during 2014. Units of measurement are in percentage.
A glance at the graph reveals that the price for nickel has witnessed a considerable decrease over the period of 1 year, while even though both zinc and copper fluctuated, the price for them have not changed much comparing to the initial price.
It is conspicuous that the cost for nickel, which had 6 percent change compared with previos month in January, plummeted by 9 percent, reaching trough in June; however, this figure saw some fluctuations between June and October before climbing to its normal price. Moreover, the cost for copper had some slight decreases until June and then stabilized after an increase of about 1.5 percent for the rest of the period.
