How to use Line Charts and Filters In Tableau

In the previous segment, you learned about the Tableau interface by creating bar charts for comparing data values across categories.

In this segment, you will learn about another type of visualization: line charts. You will also be introduced to a few additional functionalities of Tableau, which include filters. First, you understand the fundaments of the line chart. 

Now that you have learned how to create line charts in Tableau, in the next segment, you will learn about a type of line chart that is known as area maps or area charts.

So, a line chart can be between a measure and a time variable (or a discrete variable). The line chart is generally used to show how a variable has changed over time. In the next video, you will learn about a Tableau superpower: filtering. 

Filtering data is a very useful technique while presenting the data. When you create a data filter, the audience can also use it to gain insights into the data. 

Let's also look at how to save your work to Tableau Public. 

Tableau Public website is where all your data visualizations will be saved. It is like your Github account where you store and also showcase your work.
