    + The physics system has been overhauled to increase performance. The original simulation method was based on particel physics with a repulsion field (potential) around each node, + and the edges were modelled as springs. The new system employed the Barnes-Hut gravitational simulation model. The edges are still modelled as springs. + To unify the physics system, the damping, repulsion distance and edge length have been combined in an physics option. To retain good behaviour, both the old repulsion model and the Barnes-Hut model have their own parameters. + If no options for the physics system are supplied, the Barnes-Hut method will be used with the default parameters. +

    Data manipulation

    +

    + By using the data manipulation feature of the graph you can dynamically create nodes, connect nodes with edges, edit nodes or delete nodes and edges. + The toolbar is fully HTML and CSS so the user can style this to their preference. To control the behaviour of the data manipulation, users can insert custom functions + into the data manipulation process. For example, an injected function can show an detailed pop-up when a user wants to add a node. In example 21, + two functions have been injected into the add and edit functionality. This is described in more detail in the next subsection. +

    +
    +// These variables must be defined in an options object named dataManipulation.
+// If a variable is not supplied, the default value is used.
+var options = {
+    dataManipulation: {
+      enabled: false,
+      initiallyVisible: false
+    }
+}
+// OR to just load the module with default values:
+var options: {
+    dataManipulation: true
+}
+
    + + + + + + + + + + + + + + + + + + + + +
    NameTypeDefaultDescription
    enabledBooleanfalseEnabling or disabling of the data manipulation toolbar. If it is initially hidden, an edit button appears in the top left corner.
    initiallyVisibleBooleanfalseInitially hide or show the data manipulation toolbar.
    + +

    Data manipulation: custom functionality

    +

    + Users can insert custom functions into the add node, edit node, connect nodes, and delete selected operations. This is done by supplying them in the options. + If the callback is NOT called, nothing happens. Example 21 has two working examples + for the add and edit functions. The data the user is supplied with in these functions has been described in the code below. + For the add data, you can add any and all options that are accepted for node creation as described above. The same goes for edit, however only the fields described + in the code below contain information on the selected node. The callback for connect accepts any options that are used for edge creation. Only the callback for delete selected + requires the same data structure that is supplied to the user.

    + If there is no injected function supplied for the edit operation, the button will not be shown in the toolbar. +

    +
    +// If a variable is not supplied, the default value is used.
+var options: {
+    dataManipulation: true,
+    onAdd: function(data,callback) {
+        // fixed must be false because we define a set x and y position.
+        // If fixed is not false, the node cannot move.

    +

    + Because the interface elements are CSS and HTML, the user will have to correct for size changes of the canvas. To facilitate this, a new event has been added called frameResize. + A function can be bound to this event. This function is supplied with the new widht and height of the canvas. The CSS can then be updated accordingly. + An code snippet from example 21 is shown below. +

    +
    +graph.on("frameResize", function(params) {console.log(params.width,params.height)});
