What is the difference between bar graph and column graph?

How Bar Graph and Column Graph Pose Great Data Presentation

The graphs are used to compare things between groups or to visualize changes over time. However, when trying to estimate change over time, bar graphs are most appropriate when the change is large.

Nowadays, life is so hectic. To make sound decisions, you must be smart. Spending time and energy collecting data can be detrimental. Thus, graphs are very useful in understanding data interpretations. Graph charts are used by companies, corporate agencies, analysts, and data miners to translate data variations.

From yesteryears to modern days, two major graphs are used; bar graph & line graph. Bar graph possesses a scattered domain of datasets and values are normally weighed so that all the data can adjust onto the graph. When you have no regular sequence of data out of the datasets being compared, bars on the chart may be drawn in any order. Bar charts arranged from the highest to the lowest category of numbers such graphs are called Pareto charts.

What is Bar Graph?

A bar graph is one of the widely used data charts in a pictorial representation of data collection. The tower-shaped datasets are represented in the form of vertical or horizontal rectangular bars. Whereas the height of each bar is equivalent to the density of data. Such charts are known as bar graphs or bar charts.

What Does a Bar Look Like?

A bar graph more commonly resembles a skyscraper building row. It looks like a carton arrangement.

Difference Between Bar Graph and Column Graph

Column graphs are derived from bar graphs. In other words, column graphs are the offspring of bar graphs. Therefore, if you are familiar with bar graphs, you can predict the components of a column graph.

Column and Bar charts both represent data as rectangular bars whose length is defined by the value of the data. The two types of charts are typically used to compare data. They differ primarily, however, in the way they are oriented. A bar chart consists of an x-axis arranged horizontally, whereas a column chart shows data vertically. In spite of their similarities, the bar graph and column graph should not be used interchangeably due to their explicitly contradictory orientations.

A column graph, which is an offshoot of the bar graph, takes vertical bars to represent data.

In the sections that follow, we will discuss the differences based on the application and comparison of the two graphs.

When to Use Bar Graph

A bar graph is also very close to a line graph in the terms of visual appearance in that it is tailored to display various values of two or more data-oriented pyramids but rather than using a simple linear depiction it is good for use for horizontal and vertical bars that highlight a specific data value.

It is common to find bar graphs along the side of a data chart, and they are designed to scale the same or slightly deviated data values to what would be found on a line graph.

The bar graph comes in use to compare the different items between various classes or groups over time. Bar graphs are also used to map the changes over a specific period of time. When the fluctuation in data values is larger, a bar graph is the best option to represent the data.

In common talk, this type of graph is literally graspable to interpret in a more perceiving way than a line graph and that conveys data horizon information equally as well.

Bar Graph For 2 Data Values Between Different Categories

A real-time example demonstrates the test performance of five students who take the test with and without preparation.

The students under the scrutiny are John, Carla, Peter, Jetser, and Darline. We take into consideration the performance of each student.

The bar graph has two different colored graphs. The first one is Yellowish Orange and the second one is Green. Yellowish green stands for Test Without Preparation and Green for With Preparation. You can see the obtained marks in the Y-axis otherwise perceived as vertical towers while the names of the students are labeled in the Horizontal series.

Now we move toward the Column Graph for its application and depiction domains.

What is a Column Graph?

A column graph is one of the types of bar graph that is used to display some data values with the presentation in vertical bar arrangements. In actuality, a column chart is set with a graphical representation or visualization of stated data in the formation of vertical bars with rectangular shapes or columns plotted along the two axes on chart paper with the values showing the data values with measurements of the specific category of the given data.

Let’s explore the definition and applications of a column graph along with examples to learn about the various parts and uses of a column graph.

How Data Presented on a Column Graph?

Data values are commonly divided into units prevalent to the problem statement or into percentiles. These kinds of graphs provide a statistical measure of the data in a comparison rhythm.

Components of Column Graph

Column graphs share four components:

  • First comes the title of the column graph, which gives information on what data values the graph is representing.
  • Labels are used to display on each axis on the chart both x and y-axis to show the reader what each side of the graph is representing.
  • Scales are numerical values that show the values being shown on the graph. Scale numbers go in ascending order from bottom to top of the column graph, and they go on increasing by the same amount (for example, by 1, by 5, by 10, etc.).
  • In addition, the categories in the data range of the subcategories are represented by the bars. The labels should be used under each bar with a column or on the side of the column graph.

When to Use Column Graphs?

A column graph is a graph subclass that is used in statistics for arranging and representing categorical data values for comparison purposes. Column charts with the use of the bar graphs are specifically used by some visual tools in the software to present data and the bar graph and column graph look similar. However, these two classes of charts use different scenarios because of their own particular features. When to use a column chart is our question that we discuss in the following occasions for which a column chart may be preferred.

Example of Column Graph/Chart

To develop a column graph example, equal width rectangular bars are arranged for each data value with a specific height equal to the frequency under the observation of the data category as shown in the example below which shows the delivery service of a logistic company.

The delivery service uses the delivery mechanism which will occur within an observed time. The officials of the company want to know how well they are meeting their service standards during demanding hours and non-peak hours.

The dataset for this column graph goes with two categorical variables, each having two values, which shows four possible categories that observations can fall within:

  • Taken Delivery time
  • Peak Demanding Hours
  • Off-peak or Normal Hours
  • Delivery Target with Status
  • On-time
  • Late

For the observed delivery data, the bars represent the number of observations possessing each of the four related combinations of data values. Compared to off-peak hours, more delivery orders are met during peak hours. Delivery delays are rare during off-peak hours. Specifically, peak hours are observed to be the time when late deliveries occur. The observation suggests that the delivery service should be refined by working on improving the time taken for delivery during the peak hours because the column chart shows two categorical variables, it helps you make sense of the relationship between the observed data values.

Conclusion:

Column charts are considered useful for all comparison-based data analysis. The column chart is better when the labels are short and there are few values, while a bar graph will serve you when there are many ranges and combining many data sets.
