Our system will evaluate the answer based on this AI-generated description.
The image depicts a line graph titled "Average monthly change in prices of copper, nickel and zinc (2014)", tracking three metals' percentage change in price compared to the previous month for each month from January (J) to December (D). The y-axis ranges from -5% to +7%, and the x-axis represents the months. Data points for copper start at around 2% in January, peaking near 6% in May, dropping below 0% in August, and ending slightly above -2% in December. Nickel starts approximately at 0% in January, sharply rises to just below 7% in May, drops to about -4% in November, and slightly recovers to about -2% in December. Zinc begins near -1% in January, peaks at around 2% in May, falls to about -3% in July, and ends at approximately -2% in December.

The line graph compares the changes in prices of three chemical elements in 2014.
It is clearly observed that monthly figures for nickel vary considerably, whereas prices for copper and zinc remain relatively stable. The lowest results among all three meals were from January to June before increasing from July to December.
Between the months of January and June, nickel reached a peak of just over 6% and then quickly dropped to the lowest rate above minus 3%. Average price of zinc also decreases from February to June to at nearly minus 1%, as much as nickel dropped from 2% to about 0% cosequently.
From July to September, none of three meals showed changes and stand at the same prices of 1%, minus 0.5%, and minus 1%. However, all of them went down to only 1% each and then quickly increased to 1% in price respectively by the end of December.
