What is the difference between bar graph and bar chart
Like dotplots , bar charts and histograms are used to compare the sizes of different groups. If you view this web page on a different browser e. A bar chart is made up of columns plotted on a graph. Here is how to read a bar chart. Like a bar chart, a histogram is made up of columns plotted on a graph. Usually, there is no space between adjacent columns.

We've launched a new website to help you understand the data principles you need to get more answers today. Pie charts and bar charts are two of the most common charts used for visualizing data.
This tutorial will explain what they are and when to use them. A bar chart, or bar graph, is a very common two-dimensional data visualization made up of rectangular bars, each corresponding to a category and whose length represents the value of that category. The bars can be either vertical sometimes called a column graph or horizontal. For example, this figure shows a bar chart of the results of the US presidential election.
Each bar represents a candidate the category and the height of the bar represents how many votes that candidate received the value.
A pie chart is also a very common two-dimensional data visualization where categories and their values are represented. But in this case the values are proportions of a total and they are visualized as slices of a circle a pie. Here are the same results on the US presidential election represented as a pie chart. Note that instead of showing the count of votes as the value of interest, as in the bar charts, the pie chart focuses on the percent of the total votes.
In the world of data visualizations, pie charts get a lot of hate. The primary goal of data visualizations is to clearly and concisely communicate information. The main criticism against pie charts is that it is very difficult for the human eye to estimate the magnitude of angles, thus making visualization not very clear.
To compensate, pie charts require more labels to get the measurements across, making them not very concise. In short, often they defeat the main purpose of a data visualization. You can see this criticism with the previous example on the US presidential election, which was a famously close race. The pie chart makes it rather difficult to tell who won the election without referencing the legend or adding data labels to each of the slices, whereas in the bar chart, it is immediately evident who won the popular vote.
Yes, despite all the criticisms of pie charts, they can still be a great tool when used properly. From the pie chart, you have you make use of the legend on the right to see whether many of the smaller slices are equivalent. But what if you wanted to know if apples made up at least half of your sales? So which is the best chart to use for this data? If your goal for the visualization is to convey the sales amount of each product, the bar chart is the better selection.
You can even drop the legend and just label the single point of focus to make point clearly and concisely. Most data visualization tools make it very easy to plot your data as either a bar chart or a pie chart. So which should you choose? As with any data visualization, you have to be thoughtful about what its goal is. Because of the pitfalls of pie charts, bar charts tend to be the better choice. However, as we saw in the previous section, there are times when the pie chart is actually the better, more powerful visualization.
In that case the choice between the bar chart and the pie chart is purely a matter of preference. Bar charts and pie charts are very common data visualization tools, but it is important to use them correctly to ensure you convey clear and concise information.

Here are the same election results, but presented with a horizontal bar graph. When to Use a Bar Chart Vs. Get Started with Chartio.
In the case of showing change over a period of time, a column chart can also be displayed as a line chart. In a column chart the Y axis typically. Bar charts and column charts are the most commonly used charts to track changes over time between different groups. Difference Between Bar Chart and Column.
Bar charts and histograms can both be used to compare the sizes of different groups. A bar chart is made up of bars plotted on a graph. The histogram is a chart representing a frequency distribution; heights of the bars represent observed frequencies. In other words, a histogram is a graphical display of data using bars of different heights.
A chart is used to display data and explore a topic further where data in tabular form will not adequately demonstrate important relationships or patterns between data points.

Bar Graphs
The fundamental difference between histogram and bar graph will help you to identify the two easily is that there are gaps between bars in a bar graph but in the histogram, the bars are adjacent to each other. After the collection and verification of data, it needs to be compiled and displayed in such a way that it highlights the essential features clearly to the users. The statistical analysis can only be performed if it is properly presented. There are three modes of presentation of data i. The diagrammatic representation of data is one of the best and attractive way of presenting data as it caters both educated and uneducated section of the society. Bar Graph and Histogram are the two ways to display data in the form of a diagram.

In my book Select Effective Visuals , I explain that there are many different visuals to use when comparing values in a single data series. The most common visuals are the column graph and the bar chart. They look like each other, just rotated 90 degrees. Does that mean that presenters can choose either one and it will be just as easy for the audience to understand the message? In my experience I have found that there are two scenarios where a column graph communicates the message better and one scenario where a bar chart works better. The bar chart may also be helpful in dealing with one exception to the use of column graphs. Scenario 1: The message is showing the rank of values from smallest to largest in order to focus on the largest value items. In this scenario, a column graph works best.
A bar graph is a chart that plots data using rectangular bars or columns called bins that represent the total amount of observations in the data for that category. Bar charts can be displayed with vertical columns, horizontal bars, comparative bars multiple bars to show a comparison between values , or stacked bars bars contain multiple types of information.
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.
Column Graphs vs. Bar Charts – When to choose each one
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. On a vertical bar graph, as shown above, the horizontal axis or x-axis shows the data categories. In this example, they are years. The vertical axis or y-axis is the scale. The colored bars are the data series. Bar graphs display data in a way that is similar to line graphs. Line graphs are useful for displaying smaller changes in a trend over time. Bar graphs are better for comparing larger changes or differences in data among groups. Bar graphs are an effective way to compare items between different groups.
Bar Charts and Histograms
There are two differences, one is in the type of data that is presented and the other in the way they are drawn. In bar graphs are usually used to display "categorical data", that is data that fits into categories. For example suppose that I offered to buy donuts for six people and three said they wanted chocolate covered, 2 said plain and one said with icing sugar. I would present this in a bar garph as:. Histograms on the other hand are usually used to present "continuous data", that is data that represents measured quantity where, at least in theory, the numbers can take on any value in a certain range. A good example is weight. If you measure the weights of a group of adults you might get and numbers between say 90 pounds and pounds.
