What Is a Bar Graph?
A bar graph is a graphical representation of data. It uses bars that extend to different heights to depict price.
Bar graphs will also be created with vertical bars, horizontal bars, grouped bars (a few bars that read about values in a category), or stacked bars (bars containing a few forms of knowledge).
Bar graphs are ceaselessly used in trade and financial analysis to turn incessantly refined knowledge. They can put throughout knowledge briefly and effectively. Throughout the financial business, a amount chart is a ceaselessly used vertical bar graph.
Key Takeaways
- Bar graphs can display knowledge in visual ways.
- Bar graphs have an x-axis and a y-axis and can be used to test numerous categories of data.
- Data is presented by the use of vertical or horizontal bars.
- Bars can represent numerous categorised variables.
- Bars will also be grouped together for comparative purposes.
Understanding a Bar Graph
The purpose of a bar graph is to place throughout relational knowledge briefly in a visual manner. The bars display the fee for a selected magnificence of data.
The vertical axis on the left or right kind aspect of the bar graph is called the y-axis. The horizontal axis at the bottom of a bar graph is called the x-axis.
The height or length of the bars represents the cost of the ideas. The price corresponds to levels on the y-axis.
The values on the x-axis will also be any variable, similar to time, income in step with proportion (EPS), source of revenue, or cash flow. Bar graphs are incessantly used to depict purchasing and promoting amount for a security. They appear in a panel beneath a security’s price chart.

Bar Graph Houses
Certain sides of a bar graph separate them from other forms of graphs and charts.
- The bars on a bar graph have an identical width and length spacing.
- Bars can run vertically or horizontally.
- Bars proportion the equivalent position to start or base. In numerous words, all bars gets began at the bottom of the graph and extend upward (vertically) or they are going to get began in conjunction with the graph and extend right through (horizontally).
- The y-axis of a bar graph is the aspect or vertical axis.
- The x-axis of a bar graph is the bottom or horizontal axis.
- Data price is defined on the y-axis; knowledge sort is defined on the x-axis.
- Bar most sensible or extension corresponds to the cost of wisdom.
- The higher or longer a bar, the easier the fee.
- If colors are used, a bar graph would perhaps include a legend that defines them.
Bar Graph Varieties
Vertical Bar Graph
A vertical bar graph contains knowledge this is displayed vertically using rectangular bars that represent a measure of data. The rectangular bars get began and extend from the bottom x-axis. The y-axis lets in consumers to measure the height of the bars against particular levels of price inscribed on it. Usually, the higher the bar, the easier the fee.
Horizontal Bar Graph
A horizontal bar graph contains knowledge this is displayed horizontally using rectangular bars that represent a measure of data. The rectangular bars get began and extend from the aspect y-axis, In this case, the x-axis lets in consumers to measure the length of the bars against particular levels of price inscribed on it. Usually, the longer the bar, the easier the fee.
Grouped Bar Graph
Grouped bar graphs, additionally known as clustered bar graphs, represent discrete values for a few products within the equivalent magnificence. The separate, rectangular bars are grouped together. Essentially, they destroy down the overall price (or items) for (or within) the category. A grouped bar graph would possibly simply display a few magnificence, each with its separate rectangular bars. The tips will also be depicted vertically or horizontally.
Stacked Bar Graph
Stacked bar graphs, frequently known as composite bar graphs, divide a whole into parts. The ones parts are in most cases identified using different colors within the equivalent rectangular bar. So, a single rectangular bar that represents a whole will display numerous parts and colors. The parts wish to be categorised for id. The tips will also be depicted vertically or horizontally.
Bar Graph Uses
- A bar graph is used to provide knowledge visually
- It can be used by industries to place throughout refined knowledge merely
- It might read about different variables and values
- It might divulge and facilitate the know about of patterns through the years
- It might read about slightly numerous gadgets of data
- It might display categories and sub-categories
- It might display results of surveys
In technical analysis, a amount bar chart shows how so much purchasing and promoting amount there was once as soon as on a selected day. The x-axis presentations days, while a bar extending up from any day depicts the volume of amount, as measured by way of the y-axis.
When a bar graph has a well-defined 0 degree and the ideas set has every sure and destructive values in terms of this degree, every ranges of values will also be displayed. Bars above the 0 line in most cases represent sure values, while bars beneath the 0 line in most cases show destructive values.
Example of a Bar Graph
Many patrons employ a moving cheap convergence divergence (MACD) histogram, which is a popular technical indicator that illustrates the difference between the MACD line and the signal line.
Tomorrow via day price chart for Apple stock shows 3 forms of bar graphs.

Extending from the suitable is price by way of amount, one of those horizontal bar graph which shows amount dispersion consistent with price.
Along the bottom of the chart, amount is confirmed using a vertical bar graph. It presentations bars representing the number of shares traded in step with day.
In any case, the MACD histogram at the very bottom shows the separation between the MACD and the signal line. When the histogram crosses the 0 line it method the MACD and signal line have crossed, which some patrons use as a trade signal.
Bar Graph vs. Bar Chart
A bar graph shows knowledge in columns, while a bar chart is a technical analysis software that presentations the open, most sensible, low, and close prices for a selected protection all over a selected time period (similar to a day or week) using a vertical bar. Small horizontal traces extend to the left and right kind of the vertical bar to show the open and close prices. The easiest and bottom of each bar represent the high and low prices for the period.
No longer just like the bar graph, the cost bar chart very best covers similar prices and does now not extend all of the method up from the x-axis.
Bar Graph vs. Histogram
One of the most right away noticeable difference between a bar graph and a histogram is that the bars in a bar graph in most cases don’t touch each other (versus in a grouped bar graph). A histogram is one of those bar graph where the bars would not have any gaps between them.
A histogram is used to depict the frequency distribution of variables in an information set. A bar graph depicts a comparison of discrete or explicit variables. Additionally, a histogram presentations distribution frequency as a two-dimensional resolve: the height and width of rectangles have particular meanings. Each and every can vary. A bar graph is one-dimensional. The height of the rectangular bars represents something particular while the width is meaningless.
Bar Graph Obstacles
A bar graph is a technique to display knowledge. How the ideas is chosen to be displayed would possibly simply impact its interpretation. For example, if too massive of a scale is chosen, then the ideas would perhaps appear insignificant when in truth, it’s not. The dimensions does no longer allow for a suitable comparison.
In addition to, bar graphs would perhaps make knowledge look compelling when it if truth be told lacks substance. For example, having a look at only a few days value of amount knowledge in a stock does no longer provide so much similar knowledge. However comparing recent amount to amount right through the final year can give a technical broker with useful knowledge for getting and promoting possible choices.
What Are Some Benefits of a Bar Graph?
A bar graph will also be of vital use if when you’ve got to provide an explanation for the that implies of difficult knowledge. It allows you to read about different gadgets of data among different groups merely. It right away demonstrates this dating using two axes, where the types are on one axis and the slightly numerous values are on the other. A bar graph can also illustrate necessary changes in knowledge throughout a period of time.
Why Are Bar Graphs Used?
They’re used to provide knowledge, or an concept involving knowledge, in a visual method. This may make it easier for people to briefly understand the that implies of the ideas. In addition to, presenting knowledge graphically moderately than via text or the spoken word will also be an efficient and faster technique to keep in touch.
What Are the Types of Bar Graphs?
There are horizontal and vertical bar graphs. There are also stacked and grouped bar graphs. While histograms are an identical in glance to bar graphs, they represent knowledge otherwise.
The Bottom Line
A bar graph in most cases is an overly useful trade software this is serving to send refined knowledge and concepts one way or the other this is easy to understand.
The whole dating of the ideas (and, thus, the main degree that a company is making with its presentation) is illustrated using the y-axis (values) and the x-axis (categories).
Buyers use amount bar graphs every day. The ones can measure, as an example, the number of trades performed over a definite time period (similar to a day) for quite a lot of securities. Or, they are able to indicate the volume of trades at explicit prices for a security.
