A method of displaying relative information which uses special segments in a liquid crystal display within the electronic price label. The system includes the electronic price label and a number of computers. In addition to the liquid crystal display, the electronic price label includes a memory. The liquid crystal display includes first and second display portions. The first display portion displays first information in a number of first display segments within the first portion. The first display segments are linearly arranged as a relative scale. The second display portion displays second information, including price or promotional information, in second display segments in the second portion. The number of computers determine a type of first information, obtain a level of the determined type of first information, determine a list including the number of the first display segments to be activated in order to display the level of the first information, store the list of first display segments in a data file, and schedule a message to the electronic price label containing a command to activate the list of first display segments.
