VantagePoint

Co-occurrence Matrices:  Using a Co-occurrence matrix, you can spread a list across any other list. For example, using a co-occurrence matrix of "author" and "year of publication," you can see an author's publication trend over time and browse their publications by year. This way, you can see which authors have been working in an area for the longest time as well as whether they are still active.

Data from lists and co-occurrence matrices can be easily exported to other applications for visualization or customized analysis. This example shows a three-dimensional column chart created using VantagePoint data in Microsoft Excel—simply select a portion of the co-occurrence matrix, copy it to the Clipboard, and paste into Excel. 3-D graph in MS Excel
This example is created from a co-occurrence matrix of publication source-by-year. It shows the relative publication trends in the different research communities. The "research communities" are created in a list—Group using Thesaurus—and the co-occurrence matrix is created using the groups. These data are also exported directly from VantagePoint and plotted in Microsoft Excel. Line graph MS Excel
