Matrix Scatter Diagrams

Matrix scatter diagrams include diverse graph types, can be easily created and modified, and are ideal for (i) exploratory data visualization and (ii) multivariate data representation.

A matrix scatter diagram enables the individual columns in a multivariate set of data to be plotted against each other, allowing you to explore relationships between the variables, with options of connecting data points to group centroids, drawing convex hulls of groups (to aid visualizing the group boundaries and the amount of overlap), etc.

Example 1: Half matrix plots (left image displaying a scatter matrix plot; right image represents matrix plot of the same data while connecting data points to group centroids):

Example 2: Full matrix plots (left image displaying a scatter matrix plot; right image represents matrix plot of the same data while displaying convex hulls of groups):

The matrix scatter enables drawing convex hulls of groups to aid visualizing the group boundaries and the amount of overlap. The polygons can be optionally filled with the corresponding groups' marker color, and shown with or without the data points they surround.

Example 3: Multi-profile diagrams:

A multi-profile diagram can be created with a few extra clicks from an initially matrix scatter plot.
