Single Bar Chart
In Describe Image you have 25 seconds to prepare and 40 seconds to speak. Here is an example:
Example: Introduction: This line graph shows Dubai’s gold sales in 2002, measured in millions of dirhams.
In January, the price stood at 200 million dirhams, increasing sharply after February to 350 million. There was then a sharp drop followed by a more gradual decline to 150 million in July. This was followed by a brief rebound in August, where sales reached 200 million, and there was another dip in September but by December, sales returned to almost 200 million.
There were fluctuations through the year, but overall, sales stayed at around 200 million dirhams per month.
Multiple Line Graph
It is also very common to see line graphs with multiple lines. These graphs show a lot of information but remember you only have 40 seconds so don’t try and say everything. The important thing is to compare the lines. Talk about how they are similar and how they are different.
Introduction: This line graph depicts the monthly rainfall, in millimetres, in two major European cities – London and Berlin – throughout the year.
In January, the monthly rainfall stood at around 43 millimetres for Berlin and 50 million for London.There was a dip for both cities during February, however rainfall gradually increased during March and April. Rainfall peaked in Berlin in June, receiving around 70 millimetres, whereas London only received 50 millimetres. Rainfall in Berlin then decreased, with some fluctuations, however London didn’t reach its peak until October, with just over 65 millimetres.
Conclusion For both cities, the least amount of rainfall was recorded in February, and the most in June and October for Berlin and London respectively.
