Viewer Documentation

At this point, the Viewer is a very simple application intended to show the capabilities of Datagr4m's API.

Opening workspaces

Opening and saving workspace layout is easy:
  • use the File > Open menu or the "Open" button from toolbar to open an existing workspace (e.g. those provided with the downloadable demo software)
  • use the File > Save menu or the "Save" button to save the layout you've just computed and/or manually edited with mouse

When workspace is loaded without existing map, layout is started. You can let the layout run or stop it and edit items and groups' positions.

Opening local views

Hold the "B" key and click a node to bring all neighbours in a local view. Then:
  • Hit "ESC" key to return to the previous view
  • Hold the "B" key and click a neighbour to go back in the global view at the original position of the neighbour

On the right you can see a video example of navigating from global to local views on a computer network graph.

Looking at a node relationships

First, you can simply move the mouse next to a node slot (the small square where edge are incoming or outgoing) to read a summary of this relationship which will appear as a tooltip.

But you might prefer to read all relationships at the same time. To do so, hold the "L" key and click on a node to see a summary of its relationships. You can then freely move the mouse to inspect other node relationships until you hit the "ESC" key, that will exit the inspection mode.
