A method and apparatus for constructing displays of partially ordered information for event tracing and debugging from systems exhibiting concurrent processing characteristics, such as distributed systems. The method and apparatus provide displays wherein the information is maintained in the partial order while allowing intuitive scrolling of the information on the display through the implementation of predefined unidirectional movement, monotonicity, priority, maximal display and minimal change constraints. The arrangement of the information on the display may be changed by the user and appropriate labels and identifiers can be included as desired. The information may also be grouped into clusters to reduce clutter on the display, allowing information of particular interest to be examined more easily.
