Select Pairwise MD Deletion from the Graphs - Graphs of Input Data - Matrix Scatterplot menu to produce a visual (scatterplot) representation of the correlations between several variables in a matrix format (either square or rectangular as described in the Matrix Scatterplot - Casewise MD Deletion topic) using pairwise missing data deletion. When pairwise deletion of missing data is used, each individual scatterplot in the matrix is based on cases that have valid data for that pair of variables.
