- sigma.layout.noverlap
- ========================
-
- Plugin developed by [Andrew Pitts](https://github.com/apitts) and published under the [MIT](LICENSE) license. Original algorithm by [Mathieu Jacomy](https://github.com/jacomyma) and ported to sigma.js with permission.
-
- ---
-
- This plugin runs an algorithm which distributes nodes in the network, ensuring that they do not overlap and providing a margin where specified.
-
- ## Methods
-
- **configure**
-
- Changes the layout's configuration.
-
- ```js
- var listener = s.configNoverlap(config);
- ```
-
- **start**
-
- Starts the layout. It is possible to pass a configuration if this is the first time you start the layout.
-
- ```js
- s.startNoverlap();
- ```
-
- **isRunning**
-
- Returns whether the layout is running.
-
- ```js
- s.isNoverlapRunning();
- ```
-
- ## Configuration
-
- * **nodes**: *array*: the subset of nodes to apply the layout.
-
- *Algorithm configuration*
-
- * **nodeMargin**: *number* `5.0`: The additional minimum space to apply around each and every node.
- * **scaleNodes**: *number* `1.2`: A multiplier to apply to nodes such that larger nodes will have more space around them if this multiplier is greater than zero.
- * **gridSize**: *integer* `20`: The number of rows and columns to use when dividing the nodes up into cells which the algorithm is applied to. Use more rows and columns for larger graphs for a more efficient algorithm.
- * **permittedExpansion** *number* `1.1`: At every step, this is the maximum ratio to apply to the bounding box, i.e. the maximum by which the network is permitted to expand.
- * **rendererIndex** *integer* `0`: The index of the renderer to use to compute overlap and collisions of the nodes.
- * **speed** *number* `2`: A larger value increases the speed with which the algorithm will convergence at the cost of precision.
- * **maxIterations** *number* `500`: The maximum number of iterations to run the algorithm for before stopping it.
-
- *Easing configuration*
-
- * **easing** *string*: if specified, ease the transition between nodes positions if background is `true`. The duration is specified by the Sigma settings `animationsTime`. See [sigma.utils.easing](../../src/utils/sigma.utils.js#L723) for available values.
- * **duration** *number*: duration of the transition for the easing method. Default value is Sigma setting `animationsTime`.
-
- ## Events
-
- The plugin dispatches the following events:
-
- - `start`: on layout start.
- - `interpolate`: at the beginning of the layout animation if an *easing* function is specified and the layout is ran on background.
- - `stop`: on layout stop, will be dispatched after `interpolate`.
-
- Example:
-
- ```js
-
- s = new sigma({
- graph: g,
- container: 'graph-container'
- });
-
- var config = {
- nodeMargin: 3.0,
- scaleNodes: 1.3
- };
-
- // Configure the algorithm
- var listener = s.configNoverlap(config);
-
- // Bind all events:
- listener.bind('start stop interpolate', function(event) {
- console.log(event.type);
- });
-
- // Start the algorithm:
- s.startNoverlap();
- ```
