How to Use Bar Charts In Tableau

In this segment, you will learn how to create a bar chart. These are used to compare data values or trace changes in data over time. The data set that we will use for the demonstration in the next video is the same superstore data that was used in the previous segments. 

In the next video, you will understand the basics of a bar chart. 

In this video, you learned about the fundamentals of a bar chart, which are given below: 

• To create a bar chart, you need one discrete variable and one continuous variable.
• A bar chart shows the relationship between various subgroups in the data. 

Now, you will learn how to create a bar chart in Tableau. 

You can refer to the link given below to read about categorical and numeric features.

• Types of Statistical Data

In the next segment, you will learn about line charts.

In this video, you learned how to perform the following operations:

• Sorting data values in the ascending and descending order in a graph
• Changing the color of the graph

Before learning about another chart type, you will learn about the marks card. The marks card is shown in the image given below.

In the video you saw:

• Adding labels to the values in the graph
• Changing the shapes of the makers 

The only limitation that you have while creating visualizations is the 2-D space available. However, you can leverage various other elements of Tableau such as color, size, and shape to create interactive visualizations. To create a visualization for a categorical and a numeric feature, a bar chart is the most preferred option. By default, Tableau automatically selects the best visualization technique based on the features that you have selected, but you have the option to change it manually. You can use the marks card and the 'Show Me' button for the same. 

To answer the in-module questions in the rest of the sessions, you will use the Bank Marketing data set. The data set and the accompanying data dictionary are given below. Download them and keep them handy as you move forward in the module.

It offers a few options to customize your visualization. In the next video, Sean talks about the options in the marks card.
