Tableau Charts assist professionals in the field of Business Intelligence and analytics on a massive scale. A wide range of readily available and user-readable charts can be used to directly represent real-time data. Tableau can create interactive visualizations that are tailored to the audience’s needs.
Stacked Bar Charts in Tableau are charts that use bars to show comparisons between categories of data while also allowing you to break down and compare parts of a larger picture. Each bar in the graph represents a whole, with segments representing various parts or categories of that whole.
This article talks about the Stacked Bar Charts in Tableau and how they are created in Tableau. In addition to that, it also gives a brief overview of different types of charts in Tableau
What is Tableau?
Tableau is a well-known Business Intelligence and Data Analytics tool that was developed to assist in visualizing, analyzing, and understanding complex business data to make data-driven decisions. It is a smart platform that allows businesses to move more quickly and in a way that clients and consumers can understand.
The most important feature of this tool is that it makes it extremely simple for users to organize, manage, visualize, and understand data. It has tools that help in organizing and managing data like Tableau Filters, Tableau Charts, etc.
The Charts in Tableau
Tableau is a powerful tool for creating various chart types. A visual query language is used to automate the process. Depending on your data and the conclusions you want to convey, you can use a variety of charts.
Charts are simple to use and create, and they provide viewers with quick information about the data. In Tableau, there are 24 different types of charts to choose from. Charts are made up of the measurements and dimensions that you choose.
Some of the prominent Tableau Chart Types are listed below:
- Bar Chart: A Bar Chart depicts data as rectangular bars, the length of which is proportional to the variable’s value. Some bar chart types are Segmented Bar Chart, Stacked Bar Chart, Side by Side Bar Chart, etc.
- Bullet Chart: Bullet graphs are a type of bar graph that was created to replace dashboard gauges and meters. When comparing the performance of a primary measure to one or more other measures, a bullet graph is useful.
- Pie Chart: A Pie Chart is useful for organizing and displaying data as a percentage of the total. This type of graph allows the user to compare the relationship between various dimensions in a given context.
- Bubble Chart: A cluster of circles represents data in a Bubble Chart. The dimension field contains values that represent circles, while the measured field contains values that represent the size of those circles.
- Line Chart: Individual data points in a view are linked by Line Charts. They’re useful for seeing trends over time or forecasting future values because they’re a simple way to visualize a sequence of values.
- Area Chart: A line chart with the area between the line and the axis shaded with color is called an Area Chart. These graphs are the most common way to display stacked lines and are typically used to represent accumulated totals over time.

What are Stacked Bar Charts in Tableau?
Simple Bar Charts with segmented bars are called a Stacked Bar Charts in Tableau. In a Stacked Bar Chart, the bars on one axis represent different values of a field. Each of these bars is also divided into sections or segments on the inside, which provides more information about the field values.
You can compare the main values as a whole and get a better understanding of the distribution of smaller segments of a bar in this way. Stacked Bar Charts in Tableau help give a better understanding of data. In Stacked Bar Charts in Tableau, you can have up to two measure fields, or numerical axes, and a maximum of one dimension field or category axis.
When you want to visualize and compare data from different categories in one visualization, Stacked Bar Charts in Tableau are extremely useful. It allows you to fit a large number of values and details into a single graph.
Why are Stacked Bar Charts in Tableau better than other Charts?
- Easy to view Data: When comparing data points, Stacked Bar Charts in Tableau are easier to see than a combined chart. When data points are stacked on top of each other, it’s easier to see the percentage of each data point compared to the total value.
- Time-Saving: Stacked bar charts in Tableau can also help you save time by allowing you to quickly interpret data. A Stacked Bar Chart, for example, could easily display the results of a survey. Rather than manually sorting through thousands of responses, simply look at the data sets in the chart to see how many people agreed or disagreed with the question.
- Outliers stand out: Outliers stand out more in a Stacked Bar Chart in Tableau when looking at historical data. For example, if you want to see what your best-selling products were over the last decade, you can quickly see which groups are the most numerous without even reading the text. You may have noticed that your lamp sales have increased in recent years, while your chair sales have decreased. If you want to discuss increasing sales, this type of report can provide you with visual evidence to back you up.
Types of Stacked Bar Charts in Tableau
There are several types of Stacked Bar Charts in Tableau. The one you choose is determined by how you want to present your data.
- Simple Stacked Bar Chart: The full value of the bar is displayed along with the combined segment values is displayed in Simple Stacked Bar Charts in Tableau. When comparing total amounts across each segmented bar or group, this type of chart may be useful. Multiple bars are frequently available in a variety of lengths.
- 100% Stack Bar Graphs: The percentages of each group about the total amount are displayed in this graph. In this type of graph, the differences in values stand out more. Each bar will be the same length, as opposed to the data in a Simple Stacked Bar Charts in Tableau.
How to Create Stacked Bar Charts in Tableau
Below is a step-by-step guide to learning how to make Stacked Bar Charts in Tableau. To make Stacked Bar Charts in Tableau with your dataset, open Tableau on your computer and follow the steps below. You’re going to use a sample data set of sales from an electronic store.
- Step 1: Make a Vertical Bar Chart
- Choose a dimension to work with. Place Date in the Columns section after ordering it in the Dimensions section. Note that you have chosen YEAR as the Order Date field value.
- From the Measures section, you choose Sales and move it to the Rows section. The aggregation type is set to SUM in this case.
- From the right-hand visualization pane, choose the Stacked Bar Chart option. This creates a simple vertical bar chart with the x-axis representing years and the y-axis representing sales.
- Step 2: In the Columns section, you add one more detail to your chart, the Region dimension. This creates four sections or columns, one for each of the four regions. Each year is now represented by a set of four bars in each column.
- Step 3: To make the Bar Charts into a Stacked Bar Charts in Tableau, you must complete this step. In the Marks section’s Color card, you add the dimension Sub-Category.
Each bar is divided into small colored sections that correspond to different brands. You now have a Stacked Bar Chart in Tableau with each bar representing a year and the height of each bar proportional to the total sales for that year.
In addition, each bar is divided into small colored sections that represent total sales for each brand of electronic items for that year. When you hover your cursor over a colored section, it will display information such as the region, sub-category, or brand name, year, and total sales value for that brand in that year.
- Step 4: The Color card in the Marks section can also be used to change the color scheme of the Stacked Bar Charts in Tableau. You can choose a color scheme for your Bar Chart by going to the Edit Color option and browsing through the many available color palettes, then clicking Assign Palette. To finish this step, click OK.
This will allow you to finish the process of creating Stacked Bar Charts in Tableau with your preferred color scheme.
- Step 5: By adding data labels to your bar chart, you can make it more informative. Click the Show Mark Labels button in the Toolbar to add data labels to Stacked Bar Charts in Tableau.
- Step 6: Alternatively, you can drag and drop the data Label value from the Dimensions or Measures Pane to the Label shelf in Marks Card. You want to display the Sales as Data Labels in this example. As a result, drag the Sales from the Measures region to the Labels shelf.
- Step 7: If you select or highlight a specific block, the information for that block will be displayed in the Stacked Bar Charts in Tableau.
How to Add Features to a Stacked Bar Chart in Tableau
In this section, you will learn how to add any feature such as adding Totals to a Stacked Bar Chart in Tableau. Here, you will go through the steps to add a feature such as Totals to a Stacked Bar Chart in Tableau. The following steps are listed below:
- Go to the Analytics pane and drag a Reference Line into a view and drop it on Cell.
- Now set the aggregation for SUM() to Sum, set Labels to Value, and set Line under Formatting section to None in the Edit Line, Band, or Box dialog box.
- After setting up all the configurations, click on the Ok button.
- Now your view will have Totals on the top of each bar.
Similarly, you can add other features to your Stacked Bar Chart in Tableau.
