Working with Correlation Matrices

About Correlation Matrices

A correlation matrix displays the degree of correlation between multiple intersections of measures as a matrix of rectangular cells. Each cell in the matrix represents the intersection of two measures, and the color of the cell indicates the degree of correlation between those two measures.

On the Properties tab, you can specify the following options:

Name

specifies the name of the visualization.
