The image is a line graph showing the average monthly change in prices of copper, nickel, and zinc in 2014, with the x-axis representing months (January to December) and the y-axis showing the percentage change in the price compared to the previous month. The copper line starts at around 0% in January, drops to approximately -2.2% in February, fluctuates between -1% and 1% from March to October, and ends at around -1.2% in December. The nickel line starts at around -0.8% in January, drops to -2.8% in February, peaks at 5.8% in May, fluctuates between -1% and 3% from June to November, and ends at around 1.2% in December. The zinc line starts at around -0.5% in January, drops to -1.8% in February, peaks at 3.2% in July, fluctuates between -1% and 2% from August to November, and ends at around 2.2% in December.

The line graph represents the changes in the values of copper, nickel and zinc that occurred on a monthly basis during the year 2014. The data has been calibrated in percentage.
Overall, it can be seen that there was a significant decrease in the cost of nickel over the 12-month period whereas, the fluctuations for zinc and copper did not lead to a massive price growth or drop.
To begin with, initially nickel was priced highest and went through a dramatic drop of 5 percent by March. The price for copper also steadily fell during this period. Furthermore, after experiencing a steady decline, the rates dramatically fell down again and reached lowest by June. Interestingly, February onwards, zinc prices also experienced a similar trend.
Another development worth pointing is that, over a period of 3 months, beginning from July, the value for all three metals remained stagnant. During the last quarter, each metal went through fluctuations, leaving nickel priced at 1 percent in comparison to the previous month and the other two metal priced somewhat higher.
