Tableau Tip: Creating a Harvey Balls Chart
Chuck Hooper, a Senturus lead Tableau trainer, outlines how to create a Harvey Balls chart in Tableau to indicate product attribute ratings.
Think of Consumer Reports reviews: they have a circle with 1,2,3,4 quarters of a circle filled in, to rate a product, such as a car or appliance. The more segments filled in, the higher rated that product attribute is. How do you create that kind of chart with Tableau?
This simple example assumes you have a 0-4 rating already in the data.
The input source data:
- Create this view:
- Select “Shape” from the Mark Type drop down.
- Drag the “Score” field onto the Shape button in the marks card.
- Edit the Shape Legend.
- Select the “Proportions” shape palette.
- Assign shapes to values:
- The final results:
Tool C wins!
