Tableau Area Chart is a Line Chart where the Area between the Axis and the Lines fill with color(s). In this article, we will show you how to Create Area Chart with an example.
For this Tableau Area chart demonstration, we are going to use the Sample – Superstore Data Source.
Tableau Area Chart Example
To create a Tableau Area Chart First, Drag and Drop Quantity from Measures Region to Rows Shelf. Since it is a Measure value, Quantity will aggregate to default Sum. Once you drag them, Bar Chart will generate as we have shown below.
Next, Drag and Drop Year from Dimension Region to Column Shelf. Once you drag them, Tableau Line Chart will generate.
Let’s change the value from Year to All months present in each year to see the detailed monthly information (trend)
Now, you see the detailed Line chart for each month of 2014, 2015, 2016, 2017, and 2018
Let me compare the Trend 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 chart to Area Chart, Please change the Mark type from Automatic to Area Chart, as we showed below. Or, Select Area Chart from the Show Me window.
Now you can see the Area Chart
Let me change the Categories position
Add Labels to Tableau Area Chart
