Tableau Area Chart is a Line Chart where the space or place between the Axis and the Lines fill with color(s). In this article, we will show you how to Create an Area Chart with an example. For this demonstration, we will use the Sample – Superstore Data Source.
Tableau Area Chart Example
To create the Tableau Area Chart First, Drag and Drop Quantity from the Measures Region to the Rows Shelf. Since it is a Measure value, Quantity will aggregate to default Sum. Once you drag them, a Bar Chart will generate.
Next, Drag and Drop the Year from the Dimension Region to the Tableau Column Shelf. Once you drag them, a Line graph will generate. Please refer to the Discrete Area Chart chart for the remaining option.
Let’s change the value from Year to All months present each year to see the detailed monthly information (trend) in the Area Chart.
Now, you see the detailed Line chart for each month of 2014, 2015, 2016, 2017, and 2018
Let me compare the Trends for each Category. To do so, Drag and Drop the Category from Dimension Region to the Colors field present in the Marks Shelf.
Now you can see the Trend for each category. To convert the Line, Please change the Mark type from Automatic to Area. Or, Select Tableau Area Chart from the Show Me window.
Now you can see the Area Graph
Let me change the Category’s position
Add Labels to the Tableau Area Chart
Drag and Drop the Category from Dimension Region to the Text or Label field in the Marks Shelf. As you can see, the category’s Names are on the Area graph.
Let me expand the Category to show the Area Chart for every Sub-category
We further divided the chart based on the Product Name
Selecting any specific area will show you the information at that particular point.
Discrete Area Chart
Show Me has one more option called Discrete Area Chart in Tableau. Let me select the same from Show Me
Now, you can see the Discrete Area Chart for each category.
