Tableau Dual Axis

Tableau Dual Axis is useful to compare Sales Amount data with total product cost or to compare Sales against profits etc. In this article, we will show you how to Create a Dual Axis chart in Tableau with an example.

For this Tableau dual axis report, we are going to use the Data Source we created in our previous article. So, please visit Data Labels in Reports article to understand the Tableau Data Source.

Tableau Dual Axis Chart Example

To create Tableau Dual Axis chart, First, Drag and Drop the Color Group (Created in Grouping article) from Dimension Region to Column Shelf.

Next, Drag and Drop the Sales Amount from Measures Region to Rows Shelf. Because it is a Measure value, the Sales Amount will aggregate to default Sum. Once you drag them, following Chart report will be generated.

In this Tableau dual axis combination charts example, we want to compare SalesAmount against Total Product Cost. So, Drag and Drop one more measure value, i.e., Total Product Cost from Measures Region to Rows Shelf. Since it is a Measure value, the Total Cost will aggregate to default Sum.

Change Secondary Axis to Line Chart 8

We successfully created a bar and line chart. However, you can observe that For Red Color Total Product Cost value 4,696,177 is showing bigger than Sales Amount value 7,724,331. Because the Maximum value of the Sales Amount is 9 million, whereas Total Product Cost is 5 million.
