Kinds of Diagrams – GeeksforGeeks

Stats carries out a crucial function by providing a complicated mass of information in an easy manner in which makes it simpler to comprehend. Category and inventory are 2 methods for providing information in a reasonable type. Nevertheless, as the volume of information boosts, it ends up being progressively bothersome to comprehend, even after category and inventory. Therefore, information exists in the type of diagrams and charts to allow the contrast of different scenarios and to comprehend the different patterns in the information at a look.

Kinds Of Diagrams

There are various kinds of diagrams that can be utilized to provide the information. The choice of the diagram is chosen by the nature of the information, the goals of the discussion, and the capabilities and experience of the speaker.

Types of Diagrams

( Note: In this short article, we will be covering just one-dimensional diagrams and pie diagrams.)

A. One-Dimensional Diagrams or Bar Diagrams

One-dimensional diagrams are those that have just one-dimensional measurements, such as height or length.

  • In these diagrams, the magnitude of the attributes is revealed by the length or height of the bar.
  • The width of a bar is arbitrarily set to make the built diagram more sophisticated and appealing.
  • The length and height of the bars differ depending upon the variable worth. Nevertheless, the width of the bar stays consistent.
  • Width is likewise identified by the variety of bars that should be accommodated in the diagrams.
  • If there are a a great deal of products, lines can be utilized rather of bars.
  • The bars should be equidistant from one another.
  • Bars can be drawn horizontally or vertically. They are, nevertheless, typically in vertical type.

The various kinds of One-Dimensional Diagrams are as follows:

  1. Basic Bar Diagram
  2. Numerous Bar Diagram
  3. Sub-Divided Bar Diagram or Part Bar Diagram
  4. Portion Bar Diagram
  5. Broken-Scale Bar Diagram
  6. Variance Bar Diagram

1. Basic Bar Diagram

A diagram in which each class or classification of information is represented by a group of rectangle-shaped bars of equivalent width is called a Basic Bar Diagram It is the most basic kind of bar diagram. In this diagram, each bar represents one figure just. The variety of bars will amount to the variety of figures. These diagrams reveal just one attribute of the information, such as sales, production, or population figures for different years.

The magnitude of information is identified by the bar’s height (or length). The lower end of the bar touches the base line; for that reason, the height of a bar begins with the absolutely no system. These diagrams can be vertical or horizontal in design:

  1. Vertical Bar Diagram: The diagram in which the magnitude of the information exists vertically, i.e., along the Y-axis, is a Vertical Bar Diagram.
  2. Horizontal Bar Diagram: The diagram in which the magnitude of the information exists horizontally; i.e., along the X-axis is a Horizontal Bar Diagram.

The bars of a bar diagram can be aesthetically compared by their relative height, and information can be quickly understood appropriately.

Example: Present the following information in the type of an easy (vertical and horizontal) bar diagram.


Simple Bar Diagram (Vertical)

Simple Bar Diagram (Horizontal)

2. Numerous Bar Diagram

The Numerous Bar Diagram is utilized to compare 2 or more variables such as income and expense, import and export for various years, marks gotten in various topics in various grades, and so on. It is frequently described as a Substance Bar Diagram The technique for developing numerous bar diagrams is the exact same when it comes to developing a Basic Bar Diagram. Nevertheless, to identify the bars from each other, various bars are distinguished by various tones or colours.

Example: Represent the following info revealing the variety of trainees that utilize cellphones from Realme, Redmi, and OnePlus in College A, College B, and College X, utilizing a multiple-bar diagram.


Multiple Bar Diagram

3. Sub-Divided Bar Diagram

In these diagrams, the bar representing each phenomenon is divided into a number of parts. Each part or element inhabits a proportional part of the bar to its share in the overall. For instance, the bar representing the variety of trainees registered in a course can be more sub-divided into kids and women.

  • When preparing a sub-divided bar diagram, the different parts in each bar need to be kept in the exact same series.
  • It is necessary to utilize various colours or tones to separate in between various parts.
  • An ideal index ought to discuss these different colours or tones.
  • These diagrams are rather beneficial for comparing the sizes of different parts and tossing light on the relationship in between these important parts. For example, such diagrams are utilized to present information such as sales benefit from different items, a household’s expense pattern, the budget plan expense for invoices and expenses, and so on.

Example: Represent the following info utilizing a sub-divided bar diagram, revealing the variety of trainees that utilize cellphones from Realme, Redmi, and OnePlus in College A, College B, and College C.


Sub-Divided Bar Diagram

4. Portion Bar diagram

A Portion Bar Diagram is a sub-divided bar diagram that suggests the overall portion of each element instead of the magnitude. The outright magnitudes of a number of parts exist utilizing a partitioned diagram. These magnitudes can be transformed into relative worths by explaining them as a portion of the overall.

Each information element is revealed as a portion of the matching overall. Therefore, in a portion bar diagram, all of the bars are of height 100, while the various sections of the bar representing the different parts differ in height depending upon their % worth of the overall. Similar to in the sub-divided bar diagram, in the portion bar diagram, various parts can be distinguished by various tones or colours.

Example: Program the following info with the aid of a portion bar chart.


Percentage Bar Diagram

5. Broken-Scale Bar Diagram

This diagram is utilized when the worth of one variable is incredibly high or incredibly low in contrast to others. Larger bars might be broken to make area for the smaller sized bars of the series. Every bar has its worth composed on the top of the bar.

When most of the information figures are of low magnitude and several of the figures are of uncommonly big magnitude, a broken-scale diagram is utilized to provide the information.

Example: Prepare a proper diagram utilizing the following information from business imports in various years.


Broken-Scale Bar Diagram

6. Variance Bar Diagram

These diagrams are utilized to represent net modifications in information such as net revenue, bottom line, net exports, net imports, and so on

  • In these diagrams, just modifications are revealed, not the initial information.
  • The worths in these diagrams may be both favorable and unfavorable.
  • Favorable worths are shown above the X-axis (Base line), while unfavorable worths are shown listed below it.

Example: The following information reveals the sale earnings and the expense of a company in various years. Utilize a variance bar diagram to represent the profit/loss made by the company.


Deviation Bar Diagram

B. Pie Diagram

A circle can be divided into parts to reveal the ratios of various parts. A pie diagram is one such representation. Pie charts are likewise described as Angular Circle Diagrams The circle is divided into as numerous areas as there are aspects by drawing straight lines from the centre to the area.

While preparing a pie diagram, various sectors, which represent various element aspects, need to be recognized from one another through diverse tones and colours or by utilizing either meaningful or detailed labels.


Draw a pie chart to show the following expense for a regular working-class household.


The amount of the portions of overall expense is 100. It implies that the overall angle; i.e., 360 ° represents 100. Now, increase each of the portions by frac{360degree}{100}           or 3.6 ° to figure out the proportional angles.

According to the degrees of angles at the centre, the circle is divided into 5 parts. Thus, the pie diagram for the offered information will be represented as:
