Tableau Bar Chart
In this Tutorial we will discuss about Tableau Bar Chart. The tableau bar chart has consistently become one of the most popular and effective information visualization charts. Tableau bar charts has always considered useful, whether for comparing data or displaying frequency.
Topic
What is bar Chart?
We can analyze numerical information such as integers and percentages using bar charts. Every variable’s function is calculated by the length of every bar. Bar charts, for example, scale the width or height of classes or subclasses across basic, spread bars or rectangles.
Measurements can be represented vertically on the yaxis or horizontally on the xaxis in bar charts. The format is determined by the data and the problems that the visualization attempts to answer. The subjective dimension will run parallel to the quantitative measure’s axis. The standard of a bar chart is usually zero. If a different beginning point is applied, the axis should be explicitly identified to prevent the Viewers from being misled.
There are numerous additional types of bar charts.
Examples include stacked bar charts, sidebyside bar charts, clustered bar charts, and diverging bar charts.
When you should create a bar chart?
If we have a lot of data, we can make a bar chart. Followings are:
 A categorical variable
 A numerical variable
Typically, categorical data is displayed on one axis, with the associated frequencies or levels displayed from the other.
If we discuss about just the requirement specification, we can use a bar chart to display our data in the instances following.
 When we need to show how common particular categories are.
 When we wish to make a comparison between two categories.
These can’t possibly be the sole situations in which we should utilize a bar chart. Although when we have categorical variables on both axes, we can use BINS or a histogram, which is similar to a bar chart.
To use a dimensions and a measurement, we can easily create a bar chart. Even so, a single measure should be enough to make a bar chart.
Types of Bar Chart
There are two types of Bar charts –
 Vertical bar chart
 Horizontal bar chart

Vertical Bar chart
The default is a vertical bar chart, and then when we mention bar chart, we normally mean verticals bar chart.
We can maintain a measurement on the columns level and a measuring on the rows level to make a vertical bar chart.

Horizontal Bar Chart
The only difference between a horizontal and vertical bar chart is that the yaxis has a dimension. Because we have labeling with a lot of character, we generally make a horizontal bar chart.
We could simply switch the columns and rows to make a horizontal bar chart. Alternatively, you can use the switch options or try hitting ctrl + W.

Stacked Bar Chart
We’ve all run into situations where we need to dig a little further into the bar chart. Like an example, suppose we generated a bar chart for categorization versus sales, as we did previously. Then we’d like to dig deeper into the contributions.
In every category, the contributions of every segment. This is equivalent to determining how much a person is getting if they earn $1,000. It could be that his salary is $800, a rental is $100, and he has $100 in these other sources of income. When you add all of these together, you get $1000.
A stacking bar chart can be quite useful if we require this type of analysis. Let’s have a look at how to make a stacked bar chart in Tableau.
Requirement:
We have to make a stacked bar chart that is in the middle of the category vs. sales piled on section.
Tableau Side by Side Bar Charts
This is a different type of Tableau bar chart in which we need to make distinct charts for each category. It will be done similarly to how we did with the stacked bar chart. Tableau has a side by side bar chart that can be made simply by choosing it from the display me choices. The systems – based to one or more dimensions can be compared using this style of bar chart. Usually, there are multiple dimensions. For example, if we need to estimate the values of state vs sales while keeping the month in mind, we can utilize a side by side chart.
FAQs
Q. What do you mean by bar chart?
A bar graph displays data in columns, but a bar chart is a technical indicators term that refers to the use of a vertical line to depict the opening, high, low, and closing (sometimes when the friendly is excluded) values for a certain securities during a specific period of time.
Q. What is dashboards in Tableau?
A dashboard is a collection of multiple views that allows you to compare a range of data at the same time. If you have a group of viewpoints that usually evaluate every day, for example, instead of navigating to different worksheets, we may construct a dashboard that provides all of the views at once.
Q. How many types of charts are there?
Line graphs, bar graphs and histograms, pie charts, and Cartesian graphs are arguably the four most popular.
Q. What is vertical bar chart?
Graph with vertical bars. A graph in which the lengths of vertical lines ascending from the bottom are proportionate to the elements they depict. It’s useful when one of the axes doesn’t have a numerical system.
Q. What are the types of bar chart?
The bar graph is divided into six varieties regarding the structure of the bars as well as the number of components.
 Horizontal bar graph.
 Vertical bar graph.
 Double bar graph (Grouped bar graph)
 Multiple bar graph (Grouped bar graph)
 Stacked bar graph.
 Bar line graph.
