Tableau Dual Axis Chart With Overlapping Bars And A Line
Tableau is a powerful data visualization tool that allows users to create charts, graphs, and other visual representations of data. One of the most popular chart types in Tableau is the dual-axis chart, which allows users to display two measures on the same chart with different scales. In this article, we will discuss how to create a dual-axis chart in Tableau with overlapping bars and a line.
What is a Dual-Axis Chart?
A dual-axis chart is a type of chart that displays two different measures on the same chart with different scales. This allows users to compare two different sets of data that may have different units of measurement. For example, a dual-axis chart could display both sales revenue and profit margin for a company over time.
Creating a Dual-Axis Chart in Tableau
To create a dual-axis chart in Tableau, follow these steps:
- Connect to your data source and drag the desired measures to the Rows or Columns shelf.
- Right-click on one of the measures and select "Dual Axis."
- Click on the second axis and select "Synchronize Axis."
- Click on the second measure and select the desired chart type (in this case, a bar chart).
- Right-click on the second axis and select "Add Reference Line."
- In the "Add Reference Line" dialog box, select the desired measure (in this case, the same measure as the bars) and choose "Line" as the line type.
- Click "OK" to close the dialog box.
Customizing the Dual-Axis Chart
Once you have created the basic dual-axis chart, you can customize it to better display your data. Some potential customizations include:
- Changing the color of the bars and line to better differentiate them
- Adding labels to the bars and line to display the exact values
- Adjusting the size and spacing of the bars to make the chart easier to read
