Look at some of the questions below:
 Bar Graph
2. Line Graph
Whenever you are looking at the bar or line graph, please note the following:
 the title
 the xaxis (horizontal axis)
 the yaxis (vertical axis)
 units of measurement shown on the x and yaxis (e.g., percentage, kilograms, number of people or periods of time)
 a key or a legend.
Let’s dive deep into each:_
The Title
The title of a graph is a part of the information that depicts what a graph is about.
Example:
The title of the line graph is the channel on news viewing figures.
Now, your turn.
What is the title of the graph? Click/Touch when you find the answer.

The xaxis and the yaxis
Line and bar graphs always have an xaxis and a yaxis.
Click on the words below to see the x and y axes on this graph.
 The xaxis signals the horizontal axis
 The yaxis signals the vertical axis.
You need to find out what this individual axis represents in the graph.
Example:
On the xaxis:
 a year 1996 as a whole axis
 the unit of measurement is per month
On the yaxis:
 the information indicates the rate of ‘flu’
 the unit of measurement is ‘thousand’.
Now it’s your turn.
1 What information is on the xaxis and yaxis?

 The key,index or legend
An index is found in a graph where there is more than one line or bar. It tells the reader what each line or bar represents. Let’s look at an example key below.
Example:
What information is on the key of the the given graph?



Interpreting data:
Reading bar or line graph is more or less similar for which we have to combine the abovelearnt concept.
Step 1: Look at the specific point in the xaxis
Step 2: Imagine a line that passes straight from the axis to the graph
Step 3: Now imagine a line that passes straight to the vertical axis from the graph
Let’s check what we have found,
In 1996, the consumption of margarine was reported around 80 grams.
