2D Multiple Normal Probability Plot

Unlike Categorized Normal Probability Plots which produce a series of standard 2D probability plots (one for each category of cases identified by the X- and Y-axis category variables or identified by the Multiple Subset criteria), Graphs of Block Data - Normal Prob. Plots allow you to evaluate the normality of the distributions of one or more variables or cases in one multiple probability plot (in order to allow for comparisons between the block columns or rows). The values and line for each column/row will be represented by different point markers and line patterns, respectively, in the multiple normal probability plot.
