  • Fixed bug in layout algorithm (lightning bolt with = sign) that sometimes prevented it from doing anything
  • Added Edit|Copy menu item that allows you to copy the diagram to the clipboard and paste to another program
2.064 12 Sep 07
  • Reorganized Properties|Nodes menu so that some options are now under new menu item called "Symbols". Symbols refers to the circles or squares or triangles etc that you use to mark a node
  • Fixed bug in Properties|Nodes|Labels|Size|By Attribute. It was sizing labels based on the attribute one down from the one you asked for
  • Made the Egonet viewer window stay on top
  • Added feature Properties|Nodes|Labels|Repaint. This lets you draw the labels on top of the node symbols, rather than be hidden by them

  • Added similar capability to batch facility. Syntax is:

sizenodesbyattr <attributename> <minsize> <maxsize>


Sizenodesbyattr betweeness 5 20

If minsize is greater than maxsize, then the mapping is reversed.

  • Also ability in batch facility to use values of any node attribute as node labels. Syntax is:

labelnodesbyattr <attributename> [<number of decimal places>]

The number of decimal places is used when the attribute is numeric. The default number of decimal places is 3.


Labenodesbyattr betweeness 2

2.057 04 Jul 07
  • Added ability to choose line styles such as dashed, dotted, etc.

  • Fixed bug in egonet that would cause current egonet to be reset to first node whenever user clicked outside the egonet window
2.054 05 Apr 07
  • Fixed Properties|Nodes|Labels|Color|By Attribute so that it changes color of labels as it is supposed to instead of changing node colors as it was doing.
2.053 05 Mar 07
  • Made a number of adjustments to make NetDraw work better in international settings
2.051 28 Feb 07
  • Fixed bug in import dl procedure that was preventing input of nodelist2 formatted files.

2.046 02-Dec-06
  • Replaced facility for coloring lines based on which relation they represent.
2.045 02-Nov-06
  • Fixed bug in hierarchical clustering (under Analysis|Subgroups). Should cluster more sensibly now.
2.043 2-Sep-06
  • (forgot to update version number)
  • Fixed bug in emily's chart that was not permitting selection of ID variable
  • fixed another bug in emily's chart that was causing crashes when user did other things while chart dialogue was open and then returned to chart dialogue
  • Changed xml output so that color was output as hex value rather than a tcolor integer.
2.043 26 August 06
  • Added xml output capability to batch facility. You can output attributes (and graphical properties like color) or relations. Syntax is as follows:
    SAVENODESXML <filename>
    SAVETIESXML <filename>
  • Also added ability to set node shapes via an attribute in the batch facility. Syntax is:
    SHAPENODESBYATTR <attribute name>
  • Modified batch facility's color-by-attribute command to work with non-numeric attributes.
2.042 26 August 06
  • Fixed bug introduced this summer causing problems reading ties in VNA files.
2.41 06 July 06
  • Fixed bug in print procedure
2.40 19 June 06
  • Added option in right-click pop-up menu for turning labels on/off
  • Modified attribute reader to give some feedback when data have been read
  • Added ^Del button to toolbar. Pressing this causes all currently inactive or invisible nodes and lines to become permanently so. This allows you to then use the node selector, for example, to further eliminate certain nodes (without the ones originally eliminated suddenly coming back). This is the ame as the Ctrl-Del key combination that has always been there.
2.39 11 June 06
  • Fixed Simmelian ties procedures to work properly when user has made some ties inactive.
2.38 20 May 06
  • Modified Simmelian ties procedure to deliver three separate relations instead of a single valued relation, and to return asymmetric ties instead of flagging dyads as asymmetric.
2.36 23 April 06
  • Fixed transform|symmetrize procedure to work with valued data. Note that it always works on all ties whether they are currently active or not
  • Change Newman-Girvan display window so that it is always positioned at the top of the output instead of the bottom
2.34 1 April 06
  • Added ability to create new nodes. Just press button on toolbar that has a dot in the center. Then click somewhere in the graph space. A new node will appear. (Note that you can create ties between any two nodes by selecting both and right-clicking, then choosing add ties.)
2.32 26 March 06
  • Changed "fast" Factions routine to give better quality results
  • Changed internal handling of attribute data. Previously, you could get errors if you read attribute data after running subgroup routines
  • Fixed Emily's chart -- was previously grabbing the attribute next to the one the user selected
2.31 19 March 06
  • Tried to fix bug where the program sometimes fails to listen when you ask it to change size of nodes. Did not succeed.
2.30 14 February 06
  • Fixed bug added in version 2.29 that was not letting you open a ucinet file as an attribute file.
2.29 22 January 06
  • Fixed major bug recently introduced which caused saving of vna files to have various problems, including losing values in valued networks.
2.28 13 January 06
  • Fixed bug in reading 2-mode datasets
2.26 12 January 06
  • Added ability to size nodes by attribute using batch facility. The syntax is:
    • SIZENODESBYATTR <attributename>
  • Fixed bugs in batch facility that causing it to select the attribute next to the attribute that was asked for when output data to text file or coloring nodes.

  • Added additional options to the prospects and levers measures
2.22 20 October 05
  • Added directed centrality measures.
2.21 12 October 05
  • Upgraded centrality measures to handle large datasets. Also moved degree measures to this menu. Note that structural holes measures have not been upgraded yet.
  • Modified switches like edge labels, arrowheads, etc. so that user can specify whether they apply to all nodes/lines or just visible ones. Should make things less confusing.
2.19 9 September 05
  • Improved import of Pajek files that don't contain coordinates.
  • Also enabled reading of vna files that have no relations
2.18 5 September 05
  • Added the ability to select a set of nodes by lassoing.
  • Added feature to pop-up menu so that when you right-click on a set of selected nodes, you can then delete or create ties among them
  • Sometime recently I also added a "coalesce" feature to the pop-up menu. If you select a set of nodes and then press Coalesce, they all move toward each other, emphasizing their groupiness.
  • Recoded the lightning bolt with an equals sign in preparation for making it faster. Let me know if any problems.
  • Changed the Ordination routine -- which locates points making full use of tie strengths -- so that it uses the same processing as UCINET's metric scaling. Results are much better.
2.17 21 August 05
  • Fixed bug in Properties|Lines|Colors|By Node Attribute. Related to other recent bugs:  I recently changed the internal number of attributes from 1-based to 0-based. Naturally, I missed a few places ... Thanks to Emily Case and Patti Anklam for pointing this out.
2.16 16 August 05
  • Fixed bug in print routine which was adding a blank strip to the right of the page.
  • Added export to Pajek ".vec" file
  • Fixed recently-acquired bug that was preventing export to Pajek ".clu" files.
2.15 12 August 05
  • Fixed bug in exporting to Pajek ".net" files -- previously, export only worked when all nodes were active. Now you can export a subset.
2.14 11 August 05
  • Changed the way "link weights" option works on the ties panel. Previously, it had two states: checked and unchecked. Now, it has three states: checked, unchecked, and grayed out. In addition, changing the state would have immediate effect. Now, you need to press another button, such as the ties reset button (labeled "R" on the ties panel), in order to see the effects.
  • The default state is grayed out, which means that tie weights are shown or not shown for any given tie depending on that the settings of the that tie's linkweight property. 
  • The purpose of these changes is to allow a person to either set a global property for displaying link weights for all ties (checked state), or for not displaying link weights on any ties (unchecked state), or not imposing either rule and letting the properties of each individual link determine whether link weights are shown. For example, set link weights to grayed, make visible only ties of a certain tie strength, then go to Properties|Lines|Show link weights and click that on. The visible ties will now have tie strengths displayed. Now make visible all ties. You should now see tie weights only for the ties of a certain tie strength.
2.13 1 August 05
  • K-core program now outputs variable that is sorted in numerical rather than lexicographic order
  • Centrality procedure was failing to run if you didn't choose an attribute to size nodes by. Now it works ok even if you don't wish to resize nodes.
2.12 26 July 05
  • Added some node-level keyplayer metrics.
  • Fixed bug in node-level measures (e.g., centrality) that caused error messages after calculating centrality on a subset of nodes
2.10 3 July 05
  • Made change in data reader for UCINET, DL, and Pajek files. Should load large datasets much faster and eliminate "out of memory" errors. Tested it on sparse network of 3500 nodes and had no problems, though it is still slower than reading a VNA file
  • Modified component routine to provide information on the size of each component
  • Added new button on toolbar called "MC" which stands for "main component". Deletes all nodes not in main component.
  • Added "stop" window to lightning bolt layout commands. This makes it obvious how to stop the layout from iterating, and let's you know when it it is done (and therefore safe to do something else).
  • Restored ability to delete ties within or between groups of nodes. See Properties|lines|color|by node attribute. Thanks to Emily Case for pointing out that the capability had been lost.
2.9 2 July 2005
  • Fixed bug causing incorrect assignment of node properties (such as color or size) using nodes tab on right hand panel
2.8 1 July 2005
  • Massive speed-up in the "nodes" tab on the right-hand panel. Now handles 3500 nodes (if read in as a VNA file only) very quickly
  • Added two batch commands
    • LIMITNODESTO <list of nodeids>. Used to filter nodes to a particular set of nodes, as in LIMITNODESTO holly bill mary. (not case sensitive). Entering LIMITNODESTO without an argument resets the filter to make all nodes active. 
    • LABELS ON|OFF. Turn node labels on or off for all nodes currently active.
  • The batch command manual has been updated.
2.7 29 June 2005
  • Removed "feature" from Girvan-Newman routine in which pendants were removed from network prior to calculating betweenness in an effort to speed up the calculations. This caused problems with some graphs.
2.6 23 June 2005
  • Fixed bug introduced in Version 2.5 causing layout procedures to iterate endlessly.
2.5 21 June 2005
  • Changed names of centrality measures.
2.4 31 May 2005
  • Fixed problems with Symmetrize and Reciprocal Ties when working with a subgraph (i.e., when filtering)
2.3 30 May 2005
  • Reinstated the "shortlabel" field in vna files. Actually, users should migrate to "labeltext" instead of shortlabel.
  • Created separate menu choices for egonetwork measures and for centrality. Added support for directed and undirected centrality measures
  • Transform menu now has two procedures, Simmelian ties and Symmetrize, which alow creating new tie sets (relations).
2.2 23 May 2005
  • Added (rudimentary) node measures such as indegree, outdegree, effective size, constraint,  betweenness
  • Thanks to David Dreyfus, I learned how to make the right hand panel resizeable
2.1 21 May 2005
  • Moved the node selection and tie selection windows into a tabbed panel on the right of screen
  • Improved positioning of image on screen to not cutoff labels on right
  • Added right click functions such as showing ego net of current node and highlighting all nodes of same color
  • Added ability to drag all selected nodes in same direction (just drag one of the selected nodes, then release mouse: the others will follow)
  • Added egonet batch command. Syntax is DrawEgoNet <node id>
  • Documentation for batch commands is here.
1.48 25 Feb 2005
  • Hooked up the properties|lines|color|relation routine. This will color lines by which relation they belong to. When a tie exists in more than one relation, a separate color is used.
1.47 12 Feb 2005
  • Added selectrelation <relationname> to batch system. Without this, the batch system would draw a network containing all ties defined in the input data.
  • Fixed bug in batch command colornodesbyattr which did not allow quotes in arguments (e.g., colornodesbyattr "department" would previously not work).
  • Changed batch system's loadvna command to accept openvna as a substitute. Note that the information for version 1.45 had listed "openvna" as the command instead of "loadvna".
1.46 27 Jan 2005
  • Added savejpg <filename> command to the batch system.
1.45 13 Jan 2005
  • Added error message when reading vna attribute files that don't have ID field
  • Added additional batch commands. The command set now includes:
    • loadvna <filename>
    • runlayout
    • colornodesbyattr <attributename>
    • savemetafile <filename>
    • close
  • Added batch command-line parameter. So now you can run Netdraw from command line prompt and have it execute the contents of the batch file, like this:


    where the file MYBATCHFILE.TXT would contain commands like:

    loadvna datatime1.vna
    colornodesbyattr gender
    savemetafile datatime1.emf
    loadvna datatime2.vna
    colornodesbyattr gender
    savemetafile datatime2.emf
1.44 20 Dec 2004
  • Added Q modularity statistic to Newman-Girvan routine
1.43 29 Nov 2004
  • Changed import of attributes from UCINET file so as to retain 3 decimal places instead of 1
  • Modified reading of attributes from vna files to avoid shifting over of columns
1.41 2 Nov 2004
  • Added "SAVEUCINET <filename>" command to batch language, as well as "SAVEUCIATTR <filename>", for automatically saving networks and node attributes respectively in UCINET format.
1.40 24 Oct 2004
  • Added ability to for circle layout routine to sort nodes by any attribute (such as label). Still rough around the edges but works.
1.39 17 Oct 2004

1.38 1 Aug 2004
  • Simplified Open File buttons to allow reading different kinds of formats from the same dialog box. 22 Jul 2004
  • Fixed bug introduced on July 4 (version .35) that required vna files that had a "node properties" or a "tie properties" section to include a column labeled "active". Now, this is optional. 4 Jul 2004
  • Fixed bug in Save Data As|VNA which was causing deleted nodes to be saved into the file. 14 Apr 2004
  • Added new procedure under "Layout" called Emily's Chart. Is basically a generalization of the ego-net capability. Allows you to choose one or more groups of nodes (defined by an attribute vector) and then examine ties from that group to the network as a whole 13 Apr 2004
  • Added toolbar buttons to control size of nodes and labels
  • Fixed bug yielding wrong attribute label when just one attribute was read in 21 Mar 2004
  • Link and node editors added. Still very simple functionality, but will grow. 16 Feb 2004
  • The various windows work better -- more reliably. For example, they retain the attribute previously selected. 14 Jan 2004
  • Improved the node coloring window to handle larger datasets more quickly and smoothly. Also updated the node selection window. 15 Dec 2003
  • Added new facility that enables boolean AND selection of ties based on tie strengths on different relations. For example, you can select ties in which FriendshipStrength > 2 AND YearsKnown > 4. Find it under Properties|Ties|Boolean selection 15 Dec 2003
  • Fixed bug in MORE... facility that allows you to do boolean combinations of relations. Previously, it ignored any dichotomization cutoffs. Now, it respects those cutoffs. 5 Dec 2003
  • Added ability to create layouts using metric mds of edge weights -- e.g., strength of tie.
  • Added ability to layout nodes based on node attributes (such as centrality versus rank). 14 Jun 2003
  • Corrected problem with changing colors of lines based on node-attributes (i.e., lines within a group colored differently from lines between groups). 
  • Added ability to enable/disable lines between and within groups -- use the Properties|Lines|Colors|Attribute-based menu to access 27 Apr 2003
  • Corrected problem with reading tie properties in VNA files. 18 April 2003
  • Corrected serious bug in DL data reading for nodelists and edgelists with labels embedded. Previously, the structure of the network was correct but the node labels were wrong. Now it gets it right. 17 Apr 2003
  • Added Newman-Girvan routine to Analysis|Subgroups menu. This version is faster than ucinet's version. 
  • Fixed problems with running Netdraw on machines in which region/language setting was not English. This hopefully eliminates the mysterious " '0.10' is not a valid number" error. 7 Apr 2003
  • Added Factions routine to Analysis|Subgroups menu. Finds cohesive subgroups via combinatorial optimization routine 30 Mar 2003
  • Added "modify" checkbox to selector window which allows you to, say, first delete women and then within the remaining group delete instructors. I.e., nested node selection of a limited kind
  • Fixed tie window so that when you read in multiple files they are automatically limited to the tie strength specified in the tie window 23 Mar 2003
  • Fixed problem with node selector window that was missing down arrow for selecting attributes. Apparently had to do with running netdraw on machine with different screen settings than source machine 20 Mar 2003
  • Fixed problems writing VNA files involving node labels with trailing spaces 15 Mar 2003
  • Fixed problems with reading DL text files
  • Added ability to read attribute files with no labels
  • Node selector and attribute-based coloring dialog windows improved 25 Jan 2003
  • New version numbering system
  • Facilities like node selection, node coloring and tie selection are now implemented as separate windows that can remain open all the time. 
0.82 16 Dec 2002
  • Ability to choose whether node labels are placed are opaque (covering lines below) or transparent (can see lines below) has been added to properties menu
  • Default values on node properties changed. 
  • Bugs in vna complete reader fixed -- can now read files that have no attributes and no edge values
0.80 11 Dec 2002
  • Ability to read and write VNA files implemented. Several advantages: (a) VNA files can combine node attributes, node properties (color shape size, etc), and tie data all in the same text file; (b) VNA files allow textual attributes so that variables like Gender can have values "male" and "female" rather than numeric codes. 
  • Node selecting has been decoupled from node coloring -- one no longer affects the other
  • Ability to make the node labels be the values of any node attribute
0.73 7 Oct 2002
  • Fixed bug in saving metafile output
0.72 6 Oct 2002
  • Added ability to access all controls while node rotation window is open
  • Added ability to read attribute files with different numbers of nodes or different ordering of nodes than the network in memory. Procedure matches node labels. 
  • Some internal issues regarding how node properties are changed according to a node attribute were fixed
0.71 5 Oct 2002
  • Facility for displaying each node's ego network added
  • Buttons for egonetwork and mds added


29 Sept 2002
  • Fast MDS layout routine added (see Layout menu)
  • Gower layout added to menu
0.69 27 Sept 2002
  • New node shapes added, such as triangles, diamonds, and plus signs. Note: arrows not yet optimized for the new shapes, which means they don't meet up perfectly
0.68 26 Sept 2002
  • Ability to save network data as UCINET system file added
0.65 24 Sept 2002
  • Principal components layout added
  • New buttons added (duplicating existing menu options). 
  • Feature changed so that now when you change shape or size of node, it doesn't reset the colors as well
  • Ability to press Esc key to stop iteration added. Unclear whether it works -- still requires patience while it finishes current iteration.
0.64 20 Sept 2002
  • New feature added. Now, nodes can have one of two shapes: circles and squares. Shape can be applied as a general property of all active nodes, or controlled by an attribute.
  • The Pajek and Mage export routines were fixed. Previously, when the user had deleted nodes, the export routines were failing to renumber the nodes. Mage did not mind, but Pajek did.  
0.63 17 Sept 2002
  • The Pajek and Mage export routines were fixed. Previously, when the user had deleted nodes, the export routines were failing to renumber the nodes. Mage did not mind, but Pajek did.
