The disclosure generally describes computer-implemented methods, software, and systems for presenting error information. An indication is received of a selected error for a product installation. Installations are identified having a matching stream, build number and error. Other builds in a same stream having the same error are identified. Information is provided for displaying a graph having a horizontal line graph including first nodes representing builds in the same stream having the same error. Other occurrences of the error in builds of other streams are identified. Information for updating the graph is provided with parallel lines for each of the other streams, each parallel line including second nodes representing builds. An oldest one of the first nodes and second nodes is identified. Information is provided for presenting a list of potential changes occurring before the date associated with the oldest node and that are candidates for causing the error.
