Relativity of a Statistical Graph
Chen (
) proposed a concept, the relativity of a statistical graph, for evaluating
general statistical graphic displays. he idea is to place similar (different) objects at
closer (more distant) positions in a statistical graph. In a continuous display, such as
thehistogram orascatterplot, relativity always holdsautomatically. hisisillustrated
by the histogram of the Petal Width variable and the scatterplot of the Petal Width
and Petal Length variables for
Iris flowers shown in Fig.

(Fisher,

displays automatically, because they share similar petal widths and lengths. Friendly

) proposed a similar concept to order information in general visual
displays,whichtheycalledtheeffect-ordereddata display.Hurley(
