A scatter plot is best used when we want to determine whether there is a relationship or correlation between two numeric variables. Depending on how the scatter plot looks, you can infer whether the relationship between the two variables is positive or negative, strong or weak, linear or nonlinear.
Let’s now see how to build a scatter plot on Tableau step-by-step. Our goal is to create a chart showing the relationship between sales and profits for each customer from the Sample Superstore data source.
Step 1. Create a scatter plot
- Connect to the data source Sample – Superstore.
- Drag Sales to Rows.
- Drag Profit to Columns. You will see just one dot on your graph, but don’t worry!
- Drag Customer Name and drop it on Detail on the Marks card.
- Fit the graph to Entire View by choosing the option on the toolbar.
- Drag Quantity and drop it on Color in the Marks card.
Step 2. Personalize your chart
- Your scatter plot chart is now formed by empty circles. If you want some filled in dots you can just select Circle from the dropdown list in the Marks card and adjust the size by clicking on Size in the Marks card. This is what you’ll get!
