The basic form of hplot is a graph with one horizontal line for each observation included. On that line are one or more point symbols representing the values in varlist according to a common scale. hplot can produce a variety of horizontally labelled plots for data, including W.S. Cleveland's dot charts or dot plots; variations on them with continuous rather than dotted lines; D.R. McNeil's horizontal parallel line plots; and displays for showing key quantities with or without confidence intervals. By default, the data in varlist are represented on horizontal dotted lines with base at zero that extend to the maximum for each observation. If negative values are present, dotted lines also extend to the minimum. Point symbols are used to show actual values. This is version 1.4.4 of the software.
