You should spend about 20 minutes on this task. 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. Write at least 150 words.

The line chart compares the price changes of three metals in different months during 2014,including Copper,Nickel and Zinc.

According to

the chart,it can readily seen that these metals’ prices decreased after

January

and reached their bottoms in June,after that,they grew with fluctuations until December.What’s more,the changing rate of Nickel's price fluctuated from -3% to 6%,which has apparently more changes compared to the other two metals. Nickel is the most eye-catching one

due to

the massive instability of its cost.It had the highest change proportion of 6% in

January

and the lowest of -3% in June,which were the maximum and minimum data

according to

the chart.In general,it plunged from

January

and stabilised relatively at about 1% in two months(March-May) and had a dramatic drop,falling to -3% at its nadir.After that, it increased and remained unchanged at -1% from July to September.

Then

it continuously rose up from October to December after a month of short decrease. The other metal seemed to be less variable in terms of amount change.The general trend direction was quite similar,and they reached the approximate amounts in November and December.

Nevertheless

,there is a noticeable difference in

January

that the rate of Zinc’s expense changing was pretty low at 1%

while

Nickle and Copper’s proportions were high,accounting for 6% and 2% respectively.
