Fully automatic: NodeXL can build your network graphs hands free

In many cases I look at a network graph and apply a series of operations to transform it into a more presentable form. For example, I often calculate graph metrics, use Autofill columns to map data to display attributes like size, color, or shape, create clusters, sub-graph images, and then select the Harel-Koren layout and [...]

Expand and Collapse Groups of Vertices with NodeXL v.132

Clusters are now groups in NodeXL. Recently, the NodeXL team has been focused on a set of new features related to grouping sets of vertices together. In the previous version we released a feature that allowed all sorts of groupings to be recorded in the worksheet. What’s new is that the three clustering algorithms we [...]

Automatic for the people (who use the latest NodeXL!). Release v.1.0.1.128

The NodeXL team has just released a new version (v.1.0.1.128) that contains a new “Automation” feature that allows users to define a collection of operations to perform on their network graphs and invoke the complete set in a single button click AND reuse that configuration on other workbook graphs. In fact, the feature will apply [...]

Ordering smaller components in a graph – a NodeXL feature tip

From this:to this: in just a few clicks. Many network graphs contain disconnected smaller graphs, called "components", within them. Most layout algorithms do a poor job of managing to group each component in a separate space. Instead, often, components are…

Node and Venn: NodeXL can create Venn Diagrams!

NodeXL updated starting with version 1.05 with features that make it fairly easy to create basic "Venn Diagrams". A Venn diagram is a familiar way to illustrate the overlap (or lack thereof) of two or more "sets" of things. There…
