Visualizing Data with Scatter Plots in Tableau

In this video, you will learn how to create and utilize scatter plots in Tableau for data visualization. Using the sample superstore dataset, the video demonstrates how to build a scatter plot to visualize the relationship between sales and profit. The guide includes step-by-step instructions on setting up the axes, adding details such as customer names, and interpreting the scatter plot to identify profitable and non-profitable customers.

What will you learn

• How to set up a Tableau workbook and connect it to a sample dataset.
• Steps to create a sales vs. profit chart.
• The difference between a basic chart and a scatter plot.
• How to convert a chart into a scatter plot by adding details.
• Best practices for placing data on the x and y axes.
• Methods for interpreting scatter plots to analyze customer profitability.

Takeaway notes

• Scatter plots are effective for visualizing two-dimensional information.
• To create a scatter plot, you need to place one variable on the columns (x-axis) and another on the rows (y-axis).
• Introducing a detail into the scatter plot differentiates individual data points. Example: Adding customer names to the detail section shows each customer's sales and profit separately.
• Scatter plots help identify patterns such as high sales and profit, low sales and profit, and non-profitable customers.
• Majority patterns in scatter plots can guide strategic business decisions.
