There are some actions that can be performed to edit the layouts loaded in OptFlux. Here they will be detailed.
Dragging Fix/Unfix
The visualization uses a default algorithm for placing the nodes in the layouts. This algorithm (Force Directed Layout -http://en.wikipedia.org/wiki/Force-directed_graph_drawing) was changed to support fixed nodes. This means that a layout created by the user can only specify some positions of the nodes, while the others will be placed by the algorithm.
By right-clicking a node the user can specify if that node will be fixed to the position it is, or by unfixing if the layout algorithm will place it. It is also possible to fix and unfix nodes by type.
When the nodes are fixed, the user can also drag them to other positions. If multiple nodes are selected, then all fixed nodes withing the selected area will be dragged.
