Visualising changes in fund manager holdings in two and a half dimensions

We explore a multiple-view, or overview and detail, method for visualising a high dimensional portfolio holdings data-set with attributes that change over time. The method employs techniques from multidimensional scaling and graph visualisation to find a two dimensional mapping for high dimensional data. In both the overview and detail views, time is mapped to the third dimension providing a two and a half dimensional view of changes in the data. We demonstrate the utility of the paradigm with a prototype system for visualisation of movements within a large set of UK fund managers’ stock portfolios
