What is Tableau Area Chart?
Area charts in Tableau show relationships between different aspects or dimensions in a data set. This relationship is shown as the proportion of totals or percentage of certain data values. The comparison between different dimensions and values can be made by analyzing the area under each line and how does it vary with time.
There are two types of area charts in Tableau; Continuous Area Chart and Discrete Area Chart. A continuous area chart does not have individual values and hence is always measured. On the other hand, in a discrete area chart, individual values of a category are taken and hence are always counted.
Before we start creating the area chart, make sure you have the basic requirements in your data source as given below.
- Mark type – Area
- Columns shelf – Dimension
- Rows shelf – Measure
- Color – Dimension
- Detail – Dimension (optional)
How to Create a Tableau Area Chart?
Let us learn here how to create an area chart in Tableau Desktop. Open Tableau Desktop in your system and follow the steps given below to create a Tableau area chart. Make sure that you have already set a connection with your preferred data source.
Step 1: Open Visualization Pane in Tableau
Open a new sheet in a Tableau workbook. Here, on the left side, you’ll find a list of the dimensions and measures from the connected data source. At the right-most side, we have a visualization pane. You can hide or show this pane by clicking on the Show Me option. In this pane, you’ll find two options for area charts that is Area charts (Continuous) and Area charts (Discrete).
Step 2: Select Area Chart in Visualization Pane
As we know, Tableau recommends using a date field for making an area chart. So, we start by dragging a date dimension to the Columns section. Go to the visualization pane and select Area charts (Continuous) option in case it is not selected.
Step 3: Add Measure
Step 4: Add Dimensions to the Colors Box
Step 5: Basic Area Chart Creation
This creates a basic area chart where the chart is divided into three color zones of three categories which are Cameras, Laptops, and Mobile Phones. The x-axis or column axis shows four years that is 2016 to 2019. Whereas, the y-axis or row axis shows the scale for total sales.
Step 6: Make Basic Area Chart more Detailed One
We can also make this simple area chart in Tableau a more detailed one by adding another dimension (Sub-category) into the Details box in Marks pane. This will add thin lines of sub-category items like OnePlus, iPhone, Samsung, etc. in the category of Mobile Phones to give a detailed visual representation of sales data. Hover your cursor on the area segments to read the details pertaining to it.
Step 7: View Discrete Area Chart
Step 8: Conversion of Continuous Area Chart into Discrete Area Chart
This will instantly change out the continuous type area chart into a discrete type. As you can see in the screenshot attached below, the discrete area chart divides the chart space into three sections and show separate charts for the three categories.
In this tutorial, we learned the process of creating a Tableau area chart. We hope it was easy to learn how to do it from our tutorial. You can now create your own area chart for your analysis using your datasets in Tableau.
