Vertical Bar Graph

By Johaina Nor

What is an Vertical Bar Graph?

Vertical bar graph. Data displayed using vertical bars. The vertical bars have lengths that are proportional to quantities they represent. It is usually used when one axis cannot have a numerical scale.

How to make a Vertical

Bar Graph?

?

1. Collect your data

The first thing you have to do is to collect all of your data. Remember that a bar graph should show a comparison among categories. Let's say your goal is the population by country. Once you have this data, you can begin to draw the graph.

2. Give the title of the bar graph

Example:

Category 1 Category 2 Category 30

0.20.40.60.8

1Population By Country

Series 1

2. Draw an x and y-axis

This will look like a large "L" shape. Bar charts are often drawn when one set of data is expressed as a set of categories (which can be periods of time), in which case this set will be the base. The other axis will be values (sales, costs, grades, scores, production amounts, other quantities, etc.) for the base categories, groups or periods.

 5. Draw your bars

Extend the base you have marked on the bottom axis to the horizontal line labelled with the value of that bar. If the value falls between two lines, approximate where the correct value would lie. Notice that bars are normally separated (not continuous), as they are comparing the value of different but comparable events, unless this is a distribution.

6. Interpret the data

Now that you've made your bar graph, you can have a better sense of the data because you can visualize it. Now you can take a step back and take a look at the important aspects of this data. Here are some things to look for:

Outliers. Outliers are the pieces of data that fall outside the range of normal data that you gathered.

Gaps. Look for gaps between the data.

Frequency. See if there's an amount that is frequently occurring.

Clusters. Look for clusters of data.
