The relationship between various data values is displayed by a multiple bar diagram. In the graph, a column stands for each data value. With the addition of columns, multiple data points for each type of data are displayed in a multiple bar graph. These are also utilized for two or more sets of connected data. Multiple bar diagrams are those that simultaneously display two or more sets of data.

What is Multiple Bar Diagram?

Multiple bar diagram is identical to a regular bar graph with the exception that there are two or more bars in each category, one for each subdivision. This diagram is created using the same method as a straightforward bar chart with the exception that we use various tones, hues and/or dots to distinguish between various phenomena. If the sum of various phenomena is meaningless, we often draw multiple bar charts.

Example of Multiple Bar Diagram: If we plot a country’s population over five years, we can create two bars, one for the number of females and the other for the number of males, one for each year.

An illustration of a multiple bar diagram is shown below:

How to Draw Multiple Bar Diagram

Steps to draw a multiple bar diagram are as follows:

1. Step 1: On the x-axis, plot the categories.
2. Step 2: Draw a series of parallel bars for each category. Each bar in this example represents a specific subcategory (like girl/boy).
3. Step 3: On the y-axis, the corresponding numerical values are plotted.
4. Step 4: The rectangles’ (or bars’) height (length) is determined proportionally to the magnitude of the observations.
5. Step 5: Different colors should be used to differentiate between the various bars in a set. This improves the diagram’s readability and aesthetic appeal.

Advantages of Multiple Bar Diagram

Multiple bar diagram advantages are as follows:

• It can be applied to contrast two or more data points from a specific data set.
• No need to create two different diagrams.
• A single diagram contains information about two or more variables side by side.
• It looks visually appealing and is very simple to understand.

Disadvantages of Multiple Bar Diagram

Multiple bar diagram disadvantages are as follows:

• If the data contains too many subcategories or variables, it cannot be drawn. This is so that we can fit as few bars as possible into a single diagram.
