What are the features of bar diagram?

A bar diagram makes it easy to compare sets of data between different groups at a glance. The graph represents categories on one axis and a discrete value in the other. The goal is to show the relationship between the two axes. Bar charts can also show big changes in data over time.

How do you plot a bar chart?

On a graph, draw two lines perpendicular to each other, intersecting at 0. The horizontal line is x-axis and vertical line is y-axis. Along the horizontal axis, choose the uniform width of bars and uniform gap between the bars and write the names of the data items whose values are to be marked.

Where do you use a bar graph?

Bar graphs are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger.

See types of bar graphs below.

What is vertical bar graph?
