How Do You Calculate Total Number of Data Given in Pie Chart?

By dividing by 360, you may convert degrees to fractions. If you split 30 degrees by 360, you’ll get 0.083333, or 8.33 percent. But obviously, you won’t get the complete quantity of data because 8.33 percent has to be a proportion of something. The percentages and angle don’t actually tell you anything. The total number of samples or objects on which the graph is based must be known. If the TOTAL number is, for example, 3456, then 8.33 percent of it is 288. We can’t even figure out anything but overall size when you only have angles and no overall number.

You do not even Understand if they questioned 20, 1500 people or 4 million people if you have got a bar chart or “25 percent of respondents said they like ice cream, 35 percent said they prefer chocolate, and 40 percent couldn’t say” if you have a bar chart or “25 percent of respondents said they like ice-cream, 35 percent said they prefer chocolate, and 40 percent couldn’t say” if you have a bar chart or “25 percent of respondents stated they like ice-cream. Only that some proportions like ice cream, others chocolate and a lot don’t know. All we know. Let us go through the pie chart.

Pie Diagram

A pie chart is a chart that is used to display data. It’s a form of graphical data representation. It necessitates a set of categories as well as numerical variables. The phrase “pie chart” refers to a diagram in which the pie represents the entire and the slices represent the pieces of the whole.

A circle chart:

A circle chart is another name for a pie diagram. It slices or separates statistical data into sectors. In a pie diagram, each sector represents a proportionate piece of the entire. The simplest way to figure out what anything is made of is to use a pie diagram. Various graphs, such as line graphs, histograms, line plots, bar graphs, and so on, are also replaced by pie diagrams.

Pie Diagram Formula

One of the most used styles of data display is the pie chart. A pie chart has many sectors and parts, which are also referred to as aspies. Each section or sector accounts for a specific percentage of the total. All of this adds 360 °. The pie’s entire worth is always 100 percent. The following stages must be addressed in order to obtain the pie diagram formula: Collect and organize data into useful information.

Calculate the sum based on the information gathered. Divide the categories into subcategories based on the headings. Calculate the percentages of those numbers. The percentages must then be converted to degrees. = (provided data / entire value of the data) x 360 is the pie graphic formula.


A pie chart is a form of graph wherein a circle is split into sectors that each represent a percentage of the entire. Then, Pie Chart’s Practical Implications: For its simplicity of data reading as well as the availability of information, the pie chart is often utilised. A pie chart is the simplest shape since data can be easily compared.

The following are some real-life pie diagram examples:

It is used in business to compare growth areas such as earnings, turnover, exposure, and so on. It’s also utilized to express data that are categorized. Pie charts are mostly used for data comparison. Pie charts can be used in classrooms to demonstrate how much time is assigned to each component. Used to determine the relative magnitude of data such as the type of residence individuals possess, the sort of two-wheeler or four-wheeler they own, and so on. On weekends, the number of clients that visit the retail market.

Learn how to solve the below Question?

  1. The following data shows the number of students opting different subject in a college: Subjects, English, Maths, Physics, Chemistry, Eco., Commerce No. of Students, 45, 60, 20, 30, 10, 15 Construct a pie-diagram to represent the above data.

Benefits of Using Pie Diagrams:

The Benefits of Using Pie Diagrams Pie charts, as previously said, are a useful graphical representation because they make data easy to interpret at a glance. Because the pie is divided into sectors, each representing a piece of the entire, this is conceivable. The following are some of its benefits: The information is straightforward and easy to comprehend. Data is provided in a visual format.

To add a few more details, we can edit data in the form of pie chart sectors. Because the data is displayed as a pie chart, no possession stats are necessary to comprehend it. It enables a quick comparison of data. Simply glancing at the graphical representation of the Pie chart allows for fast interpretation. It is also regarded as the most effective means of communicating with readers who are misinformed or uneducated.

Pie Diagrams Have a Few Drawbacks:

Each situation has two sides to it. Some of the downsides of looking at a pie chart presentation are also evident. The following are a handful of them: When there are too many bits of information to exhibit in a pie chart, it becomes less effective.

Clutter Creation:

Clutter is created when too many pieces of information are added or separate labels are created for each item of information. It’s not always easy to decipher those numbers. Just one set of data is shown by the pie chart. A sequence of data is necessary to compare several sets. When a rapid analysis is required, it makes it challenging for readers.

Pie Chart History: 

A pie chart (or pie chart) is a statistical pie chart divided into segments to show a numerical ratio. In a pie graph, the arc length of each slice (and thus its angle and central area) is proportional to the quantity it represents. While it is named for its resemblance to a sliced ​​cake, there are differences in the way it is served. The oldest known pie chart is generally attributed to William Playfair’s Statistical Book of 1801.

Pie charts in the business and media world

Pie charts are widely used in the business and media world. However, it has been criticized and many experts recommend it to be avoided, as research has shown that it is difficult to compare different sections of a given pie chart or compare data in different pie charts. Pie charts in most cases can be replaced by other charts like bar charts, box charts, bullet charts, etc.
