Quantile plots showing by default ordered values versus cumulative probabilities are both well known and also often neglected, considering their ma jor advantages. Their flexibility and power is emphasized by using the qplot program to show several variants on the standard form, making full use...

Box plots have been a standard statistical graph since John W. Tukey and his colleagues and students publicized them energetically in the 1970s. In Stata, graph box and graph hbox are commands available to draw box plots, but sometimes neither is sufficiently flexible for drawing some variations...

Density probability plots show two guesses at the density function of a continuous variable, given a data sample. The first guess is the density function of a specified distribution (e.g., normal, exponential, gamma, etc.) with appropriate parameter values plugged in. The second guess is the...

Stem-and-leaf displays have been widely taught since John W. Tukey publicized them energetically in the 1970s. They remain useful for many distributions of small or modest size, especially for showing fine structure such as digit preference. Stata’s implementation stem produces typed text...
