How to Make Pie Chart
We will learn how to create a pie chart step by step with the help of an example. A teacher surveyed a group of students to see what their favorite hobby of each student is. Let’s take a look at the pie chart example with an explanation. The data collected is listed as follows:
Hobbies |
Number of students |
---|---|
Singing |
16 |
Reading books |
20 |
Dancing |
10 |
Painting |
30 |
Others |
24 |
Now we will see how to construct a pie chart step by step.
Step 1: The first step requires us to write down the available data in tabular form as follows:
Singing |
Reading Books |
Dancing |
Painting |
Others |
---|---|---|---|---|
16 |
20 |
10 |
30 |
24 |
Step 2: Now find the sum of all the given data. Here, the Sum of All Data = (16 + 20 + 10 + 30 + 24) = 100
Step 3: Now, calculate the percentage of each sector. We need to divide each sector value by the sum or total and then multiply it by 100.
Singing |
Reading Books |
Dancing |
Painting |
Others |
---|---|---|---|---|
(16/100) × 100 = 16% |
(20/100) × 100 = 20% |
(10/100) × 100 = 10% |
(30/100) × 100 = 30% |
(24/100) × 100 = 24% |
Step 4: Next step is to calculate the degrees corresponding to each slice. The values can be calculated as:
Central Angle of Each Component = (Given Data / Total Value of Data) × 360
Hence, The values are as follows:
Singing |
Reading Books |
Dancing |
Painting |
Others |
---|---|---|---|---|
(16/100) × 360 = 57.6 |
(20/100) × 360 = 72 |
(10/100) × 360 = 36 |
(30/100) × 360 = 108 |
(24/100) × 360 = 86.4 |
Step 5: Now, with the help of a protractor, we will measure each angle from a single point or central point and draw the circle’s sectors. The resultant pie chart will be:
Pie Chart
A Pie Chart is a pictorial representation of the data. It uses a circle to represent the data and is called a Circle Graph. In a Pie Chart, we present the data by dividing the whole circle into smaller slices or sectors, and each slice or sector represents specific data.
