Matrix Chart

A matrix chart shows relationships between two or more variables in a data set in grid format.  Essentially, the matrix chart is a table made up of rows and columns that present data visually and can be seen as the visual equivalent of a crosstabulation that divides data between the variables. The matrix chart is formed through at least two variables, for the X- and Y-categories. If there is a third or fourth variable, colour or other another dimension can be added to the matrix to represent it.
