Announcing the release of XmdvTool 7.0
XmdvTool, a software package for visual exploration and analysis of
multivariate data sets, has been in the public domain since 1994. This
cross-platform tool supports many of the most common methods for displaying
multivariate datasets, and via clustering of both records and dimensions,
is scalable to millions of records and thousands of dimensions. Some of
the new features of Version 7.0 include:
* Visualization using pixel-oriented techniques, including linked brushing
between all visualizations, powerful data reordering capabilities, and
dimension placement based on multidimensional scaling.
* Enhanced handling of nominal data, including using correspondence analysis
to do data-driven conversion of nominal to ordinal values.
* Automated visual clutter measurement and clutter-based dimension reordering.
* Interactive control of dimension binning for dimensional stacking.
* Significantly improved rendering speeds in many of the displays.
* Support for HDF4 and HDF5 data formats, as well as Oracle databases, Excel
spreadsheets, and XmdvTool's native .okc format.
XmdvTool runs on both Windows and Unix/Linux platforms. It comes with both
executables (for Windows, a self-extracting installer is available) as well
as source code and build instructions. Sample datasets and documentation
are also available.
