The graph below shows the average monthly change in the prices of three metals during 2014. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The graph illustrates how the costs of three minerals changed on average each month during 2014.

Overall

,

while

the price of nickel made up the highest proportion in January of 2014 and decreased dramatically over months, that of zinc, though fluctuating, increased slightly

at the end

of the period. The cost of copper varied over the time span and just dropped a bit in the

last

month. In January, nickel was worth 6%, becoming the most expensive metal of the three recorded but

this

figure dipped over the months. In June, the price of nickel reached the bottom with 3% less than the original cost and it was not until December that the character improved, growing to 1% in total. Meanwhile, the amount of money needed to pay for zinc fluctuated during the year between 3% and -1% with the highest portion in February and the lowest in June. The percentage of the average monthly change in the cost of copper was 2% at the beginning of 2014 and

this

figure varied significantly over the year. The value of

this

metal witnessed a decline of two and a half between May and June before rising to 1% in July and levelling off three months after that. Despite a minor fall in October,

this

figure peaked at approximately one and a half

at the end

of the year.
