Altair® Panopticon


Scatter Plot Settings

Scatter Plots are used to identify trends, clustering and outliers across a number of numeric variables, especially when investigating large data volumes.

Each scatter point is represented by:

q  X Position

q  Y Position

q  Size

q  Color (numeric or categorical)

A line of best fit can also be added to highlight outliers.

Panopticon's Scatter Plot data visualizations are easy to set up and highly customizable. You can configure your display in ways that will make the most sense to you and your users, and users have all the tools they need to filter and manipulate the Scatter Plot to concentrate on the most relevant subsets in the data.

The scatter plot settings pane is displayed after clicking the Options  button.
