It displays all uniquely identified units of stratification in a sequential diagram representing their relative temporal succession. The Harris Matrix Composer is a widely used application in the archaeological community to efficiently create and analyse HMs. However, it does not support explicit dating of HM units, which is an important information for post-excavation investigations of an archaeological site. In this paper we describe an integrated approach for a combination of stratigraphic and chronologic relations. The implicit, chronologic sequence given by the HM becomes explicit as scientists are enabled to define a hierarchical time model and assign units of the HM to temporal intervals or provide exact dating. The system maintains a consistent visual representation, which means that a correct stratigraphic layout is preserved while units are aligned to intervals of the time model. Evaluation of a real-world use case showed that this combined visualisation makes the scientific analysis and interpretation more efficient and reliable.Humancentered computingInformation visualizationInformation systemsTemporal dataSpatialtemporal systemsApplied computingArchaeology10.2312/gch.20181369235-239
