Pair Plots

A pair plot is a matrix of scatter plots for two or more variables. The diagonal of the matrix contains kernel density (KD) plots for each corresponding pair of variables.

The variables to be plotted are chosen by clicking on them in the list on the left side of the dialog. Control-click and Shift-click combinations can be used to select multiple variables. At least two variables must be selected.

The checkboxes above the list of variables can be used to specify

• Whether all of the data should be used, or only the data values highlighted on the map and in the table.

• Whether the data should be log₁₀-transformed before plotting.

The dropdown box below the list of variables allows a categorical variable to be selected, to distinguish sub-groups within the selected data set. Each sub-group will be distinctly colored on the scatter and KD plots.

The pair plots will be updated automatically whenever any change is made to the data to be plotted.

The opacity (alpha value) of symbols on the plots can be modified with the Alt-A keystroke. The Y-axis label can be rotated with the Alt-Y keystroke.
