Bar Graph What is a Bar Graph Used For. A bar graph (also known as a bar chart or bar diagram) is a visual tool that uses bars to compare data among categories. A bar graph may run horizontally or vertically. The important thing to know is that the longer the bar, the greater its value. Bar graphs consist of two axes.

A bar graph is used to compare items between different groups and track changes over a period of time. Bar graphs are best used for changes that happen over a large amount of time instead of just months or weeks. Bar graphs feature rectangular bars with lengths that are directly proportional to the values they represent.

Bar Graphs are good when your data is in categories (such as "Comedy", "Drama", etc). But when you have continuous data (such as a person's height) then use a Histogram . It is best to leave gaps between the bars of a Bar Graph, so it doesn't look like a Histogram.

Bar graphs are similar to pie chart since they are both graphs that are used for qualitative data. In comparing pie charts and bar graphs, it is generally agreed that between these two kinds of graphs, bar graphs are superior. One reason for this is that it is much easier for the human eye to tell the difference between the heights of bars than ...

Bar graphs are used to graph frequencies or amounts of data in discrete groups. Bar graphs are used to display data in a similar way to line graphs. However, rather than using a point on a plane ...

Bar Graph. There are all kinds of charts and graphs, some are easy to understand while others can be pretty tricky. There are many different types because each one has a fairly specific use. Bar graphs can be used to show how something changes over time or to compare items. They have an x-axis (horizontal) and a y-axis (vertical).

A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart.. A bar graph shows comparisons among discrete categories.One axis of the chart shows the specific categories being ...

Horizontal Bar Graph; Bar graphs can be shown with the dependent variable on the horizontal scale. This type of bar graph is typically referred to as a horizontal bar graph. Otherwise the layout is similar to the vertical bar graph. Note in the example above, that when you have well-defined zero point (ratio and absolute values) and both ...

Bar Graphs Bar graphs are used to display data in a similar way to line graphs. However, rather than using a point on a plane to define a value, a bar graph uses a horizontal or vertical rectangular bar that levels off at the appropriate level.

Bar graphs are used to match things between different groups or to trace changes over time. Yet, when trying to estimate change over time, bar graphs are most suitable when the changes are bigger. Bar charts possess a discrete domain of divisions and are normally scaled so that all the data can fit on the graph.
