Comparison Chart - A Complete Guide for Beginners
Let’s be honest – there are multiple instances in our daily life when we need to compare different things. From grocery shopping to making any crucial life-changing decision, we all have to compare several things at times.
Though, to represent these options in a better way, a dedicated comparison chart is often used. Since it has a universal appeal, a comparative bar chart is often used in almost every sector. In this post, I will make you familiar with the concept of a comparison chart and would also teach you how to draw one easily.
What is a Comparison Chart?
In a nutshell, a comparison chart provides a visual representation of various options that can be compared to each other. It can have their pros, cons, key features, etc. that would depict vital differences between these entities (or choices). Since there is no rule of thumb with comparison charts, they can depict both quantitative and qualitative characteristics. Mostly, comparison charts are easy to make and can help us in educational purposes or to make data-driven decisions.
For instance, consider this example in which different phone models are compared to each other. In this, a table is created with key parameters for each phone model. It would help readers know the difference among phone models and they can pick the device they wish to buy. Therefore, this comparison chart would be useful in both educational and decision-making features.
History of Comparison Charts
Since the concept of comparing things is not new, the history of comparison charts can be dated back to the 18th century. One of the first major comparison charts was made by William Faden about the comparison of coastal profiles. Although, it was Charles Smith's comparison chart of heights and mountains, it began to gain a wider acceptance.
Today, the concept has been evolved and is used to compare not just buildings or mountains, but executive decisions and is even used in research methodologies. To compare different entities, tables, matrices, graphs, bars, scales, bubbles, and all sorts of vectors are used.
Comparative Methodology behind Comparison Charts
Most of the comparison charts are based on a central idea, which is known as a comparative methodology. To compare different entities, we first need to find a common ground. Later, we provide a feature-by-feature comparison to know how similar or different they are. For instance, in the above picture, all kinds of mobiles are compared. We have identified at first what connects them (like display, processor, etc.) and later provided a feature-by-feature comparison of all these parameters.
Pros & Cons of Comparison Charts
The concept of a comparative bar chart or any other comparison diagram has been prospered for centuries. Needless to say, they have more pros than cons that you can understand after working on a few charts by yourself.
- Since there are no strict rules with comparison charts, they are easier to make.
- We can compare all kinds of entities and choices related to real-life instances easily.
- There is no limit to the number of things to compare or their parameters.
- Most of the comparison charts (like a table or bar) are extremely easy to draw and understand.
- They can help you provide precise information after detailed research.
- If the information is too complex, then a comparative bar chart can become harder to understand.
- Lack of standards or universally recognized rules
- If the entities have no common parameters, then we might not be able to compare them.
Five Basic Types of Comparison Charts
Although comparison charts can be drawn in several ways, some types are more common than others. Following are the 5 most commonly used comparison charts that you should know about:
A comparison pie chart is a visually appealing representation of data that is often used in sales and marketing. In this, we will simply compare different components and their share in a certain topic. For instance, you can represent the market share of products or, in this case, how the different sources of energy are compared.

A comparative bar chart is another friendly way to compare different items over a certain parameter. In this, we can even compare the frequency of a single entity by using color coding for different sets. In this comparative bar chart, you can see the output of different manufacturing plants in a certain period.

A histogram is a special form of bar chart that has concurrent values and depicts a certain pattern. The first kind involves a change in time with respect to key parameters. In this diagram, you can see the number of hours spent by students of different ages.

Also known as a line diagram, it plots frequency through another perspective (instead of time). In the end, we are able to establish a particular curve that is also known as a frequency curve.

This is another interesting comparison chart in which we use dots to represent a value (mostly, one dot = one value). The dot diagram can compare all sorts of parameters and can realize correlation comparison. They are often used in research and education as well.

Video Game Addiction Comparison
This is a comparative bar chart of a case study that was done on video game addiction for males and females of different ages. The bar graph has allocated different colors for both the genders and also divided into different age ranges. You can see that the addiction level gradually falls with the progression in age.
