Select the Quick tab of the Matrix Plots dialog to specify either a square scatter matrix plot or a rectangular scatter matrix plot. For more types of matrix plots and additional options, use the Advanced tab.
Variables. Click the Variables button to display the standard variable selection dialog, in which you can select the x- and (optional) y-axis variables for the graph. When you select Square matrix plots, you will need to select only variables for the x-axis; when you select Rectangular matrix plots, you will need to select variables for both the x- and y-axis. The selection you make will then be displayed in the area of the dialog below the Variables button.
Graph Type. Select from two types of matrix plots from the Graph Type list on this tab. Click the desired plot link below for a brief description of that type of graph. Note that additional graph types are available on both the Advanced tab and the Appearance tab.
