This blog will detail how to make a donut chart in Tableau using Sample-Superstore data.
To create a donut chart, we first need to know the dimension on which we want to segregate and measure to define the proportion. So, in this case the “Category” can be used as the dimension and “Sales” as the measure.
Following are the steps to create a doughnut chart in Tableau:
1. Connect to Sample-Superstore dataset: Open the Tableau Desktop and select the “Sample-Superstore” dataset
2. Go to Sheet1:
3. In the “Marks” card, select chart type as pie
4. Drag the “Category” field to “Color” and “Sales” measure to “Size” & “Label” marks card
5. Now, drag the “Number of Records” to “Rows” shelf
6. Select the “Number of Records” field in “Rows” shelf and change the default aggregation from “Sum” to “Minimum”.
