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 line graph illustrates the change in the prices of three metals(copper,

nickel

and

zinc

) during the

year

2014.

Moreover

, all values are measured in proportions.

Overall

, the

nickel

had significant fluctuations,

while

copper and

zinc

were more balanced.

Moreover

, by the end of the

year

, all of them were nearby for each other. Over the first half of the

year

costs of metals decreased. And

then

, they experienced a slight increase for the end of the

year

. The biggest growth was made by

nickel

, and it was approximately 6 per cent in January.

While

, copper and

zinc

's maximum changes were about 2%,and 3%, and like a

nickel

, they had records at the beginning of the

year

, especially January and February.

On the other hand

, the lowest proportional change was made by

nickel

, which was about -3%, in the middle of the period, June.

Whereas

nickel

and

zinc

had less variable decreases, the record was roughly -1%.
