Bar graphs can compare items or show how something changes over time. Also known as the clustered bar graph, it plots numeric values for levels of 2 or more categorical variables instead of one side-by-side. Here, the rectangular bars are grouped by position for levels of one categorical variable, with the same colors indicating the secondary category level within each group.
What Constitutes a Bar Graph?
Not only does that baseline make it easier for readers to compare bar lengths, it also maintains the truthfulness of your data visualization. A bar chart (aka bar graph, column chart) plots numeric values for levels of a categorical feature as bars. Levels are plotted on one chart axis, and values are plotted on the other axis. Each categorical value claims one bar, and the length of each bar corresponds to the bar’s value.
During declines, the bars typically get longer, showing an increase in volatility. Declines are also marked by more down (red) price bars compared to up (green) bars. Because a bar chart shows the opening, high, low, and closing prices for each period, there is a lot of information that traders and investors can utilize. It presents exactly the same information as a bar chart, but with different aesthetics. Instead of bars, we have lines topped by dots at their endpoints.
While these plots will have more elements for a reader to parse, they provide a deeper understanding of the distribution of values within each group. Other times, the values may be an average, total, or some other summary measure computed separately for each group. In the following example, the height of each bar depicts the average transaction size by method of payment. Note that while the average payments are highest with checks, it would take a different plot to show how often customers actually use them. For those ready to dive deeper, FusionCharts offers the perfect platform to create polished, interactive bar charts that stand out in any report or dashboard.

FusionCharts offers highly customizable bar charts with interactive features like tooltips, drill-downs, and real-time data updates. Whether you need a simple bar chart or an advanced multi-series one, FusionCharts provides flexibility to suit various use cases. Learn more about comparing different chart types like bar graphs and pie charts and how to create bar graphs on Google Docs. A bar graph, also known as a bar chart, is a graphical display of data using bars of different heights or lengths. Each bar represents a category of data, and the size of the bar represents the value or frequency of the category it corresponds to.
This can make it easier for people to quickly understand the meaning of the data. In addition, presenting data graphically rather than through text or the spoken word can be an efficient and faster way to communicate. This is an example of a double bar graph from which we can quickly identify the sport that is most popular of all and the least popular one. The title and labels give information Bitfinex Review about the number of items under certain categories which is essential for reading the graph.
The range between the high price and low price of an asset is represented by the vertical height of a bar chart. This bar uses horizontal lines to note the opening and closing prices. A bar chart is a collection of price bars, with each bar showing price movements for a given period. Each bar has a vertical line that shows the highest and lowest prices reached during the period. The opening price is marked by a small horizontal line on the left of the vertical line, and the closing price is marked by a small horizontal line on the right of the vertical line.
This four-course series allows you to gain an in-depth understanding of basic data analysis and visualization skills used by successful data analysts today. Professionals within the business and financial industries often utilize bar charts for multiple purposes to succinctly showcase complex information and data. For example, a volume chart can depict fluctuations in trading volume over time. Opposite from a vertical bar chart, the horizontal bar chart has the starting point for the bars on the y-axis.
If the close is far above the open, it shows buyers were very active during the period, which may indicate more buying in future periods is forthcoming. If the close is very near the open, it shows there was not a lot of conviction in the price movement during the period. Choose Horizontal Bar Graphs when dealing with long category names, as they work better when there isn’t enough space on the x-axis. Conversely, if the market close is much lower than the period high, it means there were more sellers near the end of the period and could represent a more bearish outlook. They’re used to present data, or a concept involving data, in a visual way.
Bar charts remain one of the most effective tools for comparing categories, tracking trends, identifying outliers, and understanding part-to-whole relationships. By choosing the right type of bar chart and following best practices, you can communicate your data clearly and compellingly. Whether you’re a data enthusiast or an analyst, leveraging bar charts can enhance how you present and interpret information.
He bought 6 kg of potatoes, 8 kg of onions, 5 kg of tomatoes, and 3 kg of capsicum. Error bars indicate the standard deviation for transaction amounts for each payment type. The variability is lower for credit and debit cards compared to the others. If the bars from a previous example were vertically oriented, the Team tick labels would need to be rotated in order to be readable. Roles of the vertical and horizontal axes may be reversed, depending on the desired application.
Uses of Bar Graph / Applications of Bar Graphs in Real-Life
Thus, a bar represents the whole, and each segment is a part of the whole. It represents the data set in a visual form, which helps to observe and analyze the data easily. Data representation gives a clear idea of what the information means by giving it visual context through graphs. A 1-minute bar chart, which shows a new price bar each minute, would be useful for a day trader but not an investor. A weekly bar chart, which shows a new bar for each week of price movement, may be appropriate for a long-term investor, but not so much for a day trader.
- Stacked bar graphs, also known as composite bar graphs, divide a total into parts.
- Stacked bar charts present the information in the same sequence on each bar.
- Larger numerical values appear as longer bars within the graph to create a simple comparison between the frequency of data within each grouping.
- Similar to clustered bars, stacked bar charts can be vertical or horizontal.
- Like the relationship from the bar chart to a histogram, a line chart’s primary variable is typically continuous and numeric, emphasized by the continuous line between points.
What Are the Types of Bar Graphs?
Yet comparing recent volume to volume over the last year can provide a technical trader with useful information for trading decisions. Bar charts are helpful in many situations, including those that call for analyzing or graphing categorical data. In any situation where data is split into multiple groups, a bar chart may be an excellent way to represent it visually. Such data are presented as either vertical or stacked bar graphs. The seasons on the x-axis represent the categorical data and the number of students on the y-axis represents the numerical possible values.

It also shows the volatility avatrade review of the security or asset over a given period which is the change between the period high and the period low. The volatility can be calculated by taking the period high and subtracting the period low.
