Select Scatterplots w/Histograms from the Graphs - 2D Graphs menu to display the 2D Scatterplots with Histograms dialog. This type of graph combines features of the regular X-Y scatterplot with histograms of the X and Y variables. Histograms are plotted parallel to the x- and y-axes of the graph, the X-histogram at the top and the Y-histogram at the right. Each component graph in this compound graph can be edited by clicking on it.
