The Data Table

Changing Marker Properties

You can change the markers used to represent observations. You can use marker shapes and colors to represent observations that share common properties. Marker shapes often used to discriminate observations with different values of a categorical variable (for example, male versus female). Marker colors can also be used for this purpose, or can represent a continuous variable. Chapter 9, "General Plot Properties," describes coloring markers by a continuous variable.
