  • improved integration of color brewer colors
  • extended color table functionality

New in Visone 2.6.4 (Sep 22, 2011)

  • [IO / Analysis] New tab R Console provides the possibility to send/receive networks including attributes to/from an R-environment, where these can be manipulated directly. In R, networks are represented by the igraph library.
  • [IO / Analysis] Knime connection: Networks may be sent/received to/from a running Knime instance, a powerful visual data mining tool developed at the University Konstanz.
  • [IO] Link list import: Networks can now be opened from csv-style link lists. The first two columns in the csv-file must contain node identifiers corresponding to source and target node; additional columns are considered as additional link attributes.
  • [IO / Attributes] New attribute type dyad attributes: Dyad attributes provide a way to encode attribute values for each pair of nodes (dyads), mainly used with RSiena. Dyad attributes may be imported and exported from/to csv-files using the attribute manager.
  • [Transformation] New network-level transformation “dyad graph” creates a complete graph from the current network displaying all dyads as links and converting all dyad attributes to link attributes of the dyad graph.
  • [Visualization - Layout] Added a layout algorithm “stress minimization (dyad attributes)” to represent distances given by dyad attributes.
  • [Visualization - Layout] Slight changes in the GUI for dynamic layouts. Added a new layout algorithm “linked layout” that links each node to each of its instances in other networks, and the possibility to calculate and apply an “aggregated layout” to a network collection.
  • [Visualization - Geometry] Procrustes analysis: added the option to consecutively perform a procrustes transformation to the previous network in a collection.
  • [Visualization] Added an option to apply visualization algorithms to all open networks. Please note that mapping algorithms are applied to networks individually; thus, if a visualization is applied to all open networks, colors, sizes etc. do not share a common scale.
  • [GUI] Simplified selection tab.
  • [GUI] Option added to save/discard all changes to networks if several networks are closed (i.e., when closing visone or if “close all tabs” / “close other tabs” in the context menu of a network tab is performed).

New in Visone 2.6.1 (Aug 6, 2010)

  • [IO] resolved a problem when loading/saving graphs.
  • [IO] resolved a problem that caused image exports to be too large.
  • [GUI] Templates now incorporate label font and font-size.

New in Visone 2.5.1 (Feb 10, 2010)

  • [Attributes] It is now possible to import edge attributes into the network by an adjacency matrix in csv format, similar to graph import by adjacency matrix. See Attribute Manager → Edges → Export & Import. Row/Column-labels may be used to match rows/columns to the ids of the nodes in the network.
  • Error Fixes:
  • [Visualization - Layout] Centrality Layout now keeps the size of the nodes when applied more than once.
  • [Visualizaation - Layout] Status Layout now optionally provides drawing of status niveaus.
  • [IO] Background information, i.e., radial/status niveaus are now exported with the graph.
