  • Patent number: 11875025
    Abstract: Computer systems and methods may display multi-dimensional data sets in a dynamically-generated ocular view, which may show the relationship between data points in the different dimensions. For example, such a data set may include in one dimension results of one or more laboratory tests and, in another dimension, body systems or functions that the respective tests may relate to. The ocular view may depict the relationships between the tests and the systems. By being generated dynamically, moreover, the ocular view may be able to present this information for arbitrary sets of test results, without a template having been generated in advance to specify the layout of some particular combination of results.
