The by option of the graph command is often used to show groups or subsets of some data in separate panels or facets of a graphical display. If groups are unequal in size, the result may seem awkward or inefficient in use of space.
Devices to allow such groups to be shown directly without using a by() option are explained and exemplified for graph dot and its siblings and for graph twoway.
New variables to show rank within groups and (if needed) separation of groups are easily constructed. Group summaries such as medians may easily be added.
Graph types shown are dot charts, quantile plots, and displays using spikes to show differences between variables. Data examples are for ocean salinity and changes in weight of anorexic girls.
