For this Tableau Area chart demonstration, we are going to use the Sample – Superstore Data Source.
Tableau Area Chart Example
In order 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 be aggregated to default Sum. Once you drag them, Bar Chart will be generated as we shown below.
Next, Drag and Drop Year from Dimension Region to Column Shelf. Once you drag them, Line Chart will be generated as we shown below.
Let us change the value from Year to All months present in each year to see the detailed monthly information (trend)
Now you can see the detailed Line chart for each month present in 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 and every category. In order to convert the Line chart to Area Chart, Please change the Mark type from Automatic to Area Chart as we shown 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
Drag and Drop the Category from Dimension Region to the Text or Label field present in the Marks Shelf. From the below screenshot you can see the categories Names on Area Chart.
Detailed Tableau Area Chart

Selecting any specific area will show you the information at that particular point.
