Frequently Asked Questions

How to write a line graph in IELTS?

  1. Candidates should try to include all information from the two-axis and the names of categories.
  2. They should put all main trends in an overview statement and not divide their key points into different paragraphs. It should be made sure to include the main increases and decreases shown.
  3. Candidates should use diverse vocabulary and avoid making spelling mistakes. 
  4. They should use data to support their sentences. 
  5. An empty line should be left between paragraphs to make reading easier. It is not a rule but a strong recommendation.
  6. If the line graph contains too many lines and a lot of movement, candidates should be selective as they are marked on the ability to select key features. 
  7. Candidates should not spend more than 20 minutes on task 1 as they will need a full 40 minutes for task 2.
  8. Candidates should write 150 words or more. They should aim for about 160-190 words and avoid writing below the word count.

How many types of graphs are there in IELTS?

The IELTS exam consists of 6 types of charts: maps, bar chartspie charts, process diagrams, tables, or line graphs, and candidates need to write a report about one of these.

How many parts of a line graph are there?

There are six parts of a line graph:

  1. The title: It provides a short description of the graph's content. This makes it easier for the reader to figure out what they are about to look at.
  2. The legend: It explains what each line means. As the legend on the map, it helps the reader understand what they are looking at.
  3. The source: The source explains where the candidates found the information in the graph. 
  4. Y-axis: The y-axis in line graphs goes vertically (up and down). The amount of anything being measured is usually represented by numbers on the y-axis.
  5. The data: The information, or data, contained in the graph is the most significant aspect of it. Line graphs can display multiple groups of data at once.
  6. X-axis: The horizontal axis is called the x-axis (flat). The x-axis usually has numbers that indicate different time periods or the names of the entities being compared.

What are the different types of line graphs?

There are three types of line graphs:

  1. Simple line graph: These graphs have only a single line plotted on them.
  2. Multi-line graph or polyline graph: These graphs are commonly used for comparison and have more than one line on the same axis.
  3. Compound line graph: These graphs are an advanced version of multi-line graphs and the area between two lines is shaded, which indicates the size of that part.

What is the difference between a line graph and a linear graph?

Although they are both made up of line segments, there is a significant difference between them. The difference can be seen in the figure that results from combining the line segments. In a linear graph, all of the points are collinear and hence lie on a line. They may or may not be collinear in the case of a line graph.
