NodeXL v.224 is now available!  224 contains many updates since the last public release (219).

NodeXL 224 now provides:

  • The way the Size column on the Vertices worksheet affects the actual size of vertices in the graph pane has been changed. The Size values now determine the area of the vertices instead of the radius of the vertices, and the range of actual vertex sizes has been compressed into something more sensible.
  • If you import a Twitter search network (NodeXL, Data, Import, From Twitter Search Network), your graph has groups, and you calculate Twitter search network top items (NodeXL, Analysis, Graph Metrics), the following additional columns now get added to the Groups worksheet: Top Replied-To in Tweet, Top Mentioned in Tweet, Top URLs in Tweet, Top Domains in Tweet, Top Words in Tweet, Top Word Pairs in Tweet, and Top Tweeters.
  • If your graph has groups, you tell NodeXL to lay out the groups in boxes (NodeXL, Graph, Layout, Layout Options), and you combine intergroup edges, the maximum width of the combined intergroup edges is now three times what it was before.
  • If you calculate word and word pair metrics (NodeXL, Analysis, Graph Metrics), the order of the word pairs is now considered, so that "brown fox" and "fox brown" are counted as separate word pairs. They used to be counted as one pair.
  • If you calculate word and word pair metrics, NodeXL now calculates something called "mutual information" for the word pairs. It's described in the Graph Metrics dialog box.

1.0.1.223 (2012-08-23, private release)

  • If you import a Twitter, Flickr or YouTube network (NodeXL, Data, Import) and then automate the workbook (NodeXL, Graph, Automate), and you tell NodeXL to save the workbook if it has never been saved before, the file name NodeXL uses now contains more information about the import: "2012-08-15 11-29-48 NodeXL Twitter Search London Olympics.xlsx", for example.
  • If you import a Twitter search network and you have opted to have NodeXL add a description of the imported data to the graph summary (NodeXL, Data, Import, Import Options), then the graph summary will now state the tweet period with greater precision: "The tweets were made over the 9-hour, 12-minute period from...", for example.
  • If you import a Twitter network and you tell NodeXL to add a Tweet or Latest Tweet column, a new Domains in Tweet or Domains in Latest Tweet column also gets added.
  • If you tell NodeXL to calculate Twitter search network top item metrics (NodeXL, Analysis, Graph Metrics), the Twitter Search Network Top Items worksheet will now include the top domains in the tweets.
  • If you import a Twitter network and you tell NodeXL to expand the URLs in the tweets or latest tweets, the URLs are now expanded twice if necessary--once to expand the "http://t.co/..." URL, and again if that expanded URL is itself a shortened URL, such as "http://bit.ly/...". This significantly increases the import time. [This change was a mistake and was reversed in version 1.0.1.224.]
  • For programmers only: The Smrf.NodeXL.Algorithms.ClusterCalculator class will now calculate clusters by clique, via the SNAP library.

1.0.1.221 (2012-08-13, private release)

  • If you automate the workbook (NodeXL, Graph, Automate), there is a new option in the Automate dialog box to have NodeXL save the workbook if it has never been saved before. The file name includes import information if you imported a network from Twitter, Flickr or YouTube, or just the date and time otherwise.
  • You can now group vertices by D-parallel motifs, not just two-parallel motifs.
  • Collapsed D-parallel motifs now look like tapered diamonds instead of crescents.

1.0.1.220 (2012-08-01, private release)

  • If you export many graph images to the NodeXL Graph Gallery (NodeXL, Data, Export, To NodeXL Graph Gallery), you can now specify that all your exported images be the same size.
  • When you calculate word and word pair metrics (NodeXL, Analysis, Graph Metrics) and you select the "count by group" option, the results now include metrics for the entire graph as well as for each group.
  • When you calculate Twitter search network top item metrics, the results now include the top words and top word pairs in the tweets.
  • For programmers using the NodeXL Class Libraries: You can now control the alpha (opacity) of the rectangles that are drawn behind label annotations to make them more legible. See the new NodeXLControl.GraphDrawer.VertexDrawer.BackgroundAlpha property. (You can set this to zero as a temporary workaround for the .NET Framework version problem discussed at http://nodexl.codeplex.com/discussions/389327.)
