What’s a Scatter Plot Chart?

Scatter Plot Charts are sets of data points plotted in x and y axis to represent two sets of variables. The shape those data points create reveals the positive or negative correlation of large amounts of data.

When to Use a Scatter Plot Chart

Scatter Plot Charts reveal trends, clusters, patterns, and relationships in large amounts of data points. They can show lung capacity compared to free-diving depth, the magnitude of earthquakes compared to their duration, or profits compared to expenditures in multiple business divisions. The data correlation shown in Scatter Plot Charts can be interpreted in ways such as: positive correlation, negative correlation, null correlation, linear correlation, exponential correlation or outliers.

Tips for Creating Scatter Plot Charts

  1. Start Y-Axis Value at 0 to avoid truncating Scatter Plot Charts data values visualization.
  2. Use size and dot color to encode additional data variables.
  3. Trend lines help to show correlation between variables.
  4. Don’t compare more than two trend lines, this causes confusion.


This is particularly true when to large amounts of data need to be presented easily and clearly. For that, these slides facilitate including data in PowerPoint tables that automatically and quickly update and outline complex tables into memorable charts.
