Line Graphs
Line graphs are used to show a trend or pattern which usually takes place over a period of time. It is important to look at the overall pattern on a line graph as well as the significant features within it.
For example,
It
shows the population of D
enmark
from 1996 to 2007. You can see that in 1996 the population was 5.25
million and that by the year 2007 it had grown to 5.45 million.
When you write about a line chart it is important to look first at the Chart Title. This tells you what information the graph displays and you can use this information in your description.
Then look at the X and Y axes. The titles of these axes sometimes give you information you can use in your description. It is important also to look at the UNITS. On the Y-axis in this graph the units are millions. The population of Denmark in 1996 was not 5.25, but 5.25 million people.
Line graphs describe change. When describing these graphs you must answer the question, "What changed?". In this case we can see that the population of Denmark increased from 1996 to 2007.
We can also ask the question, "How did the population change?". Because the line is fairly smooth, we can say that the population increased steadily.
Lastly, we can ask the question, "How much?". In this case, "How big was the change in population?" The population in 1996 was 5.25 million and in 2007 it was 2.45 million. So there was an increase of 0.2 million or 200,000 people.
To provide a good description of the graph, it is necessary to answer the following questions:
What exactly does the graph show? (Use the chart title to help you answer this question)
What are the axes and what are the units?
What changed?
How much did it change?
“This graph shows population change in Denmark from 1996 to 2007. Denmark's population grew steadily from 5.25 million in 1996 to 5.45 million in 2007, an increase of 200,000 people.”
