Nodes configuration

+

+ Nodes can be configured with different styles and shapes. To configure nodes, provide an object named nodes in the options for the Graph. +

+ +

+ For example to give the nodes a custom color, shape, and size: +

+
+var options = {
+  // ...

+    color: {

+      }
+    },
+    shape: 'star',
+    radius: 24
+  }
+};
+
+ +

+ The following options are available for nodes. These options must be created + inside an object nodes in the graphs options object.

Clustering

+

+ The graph now supports dynamic clustering of nodes. This allows a user to view a very large dataset (> 50.000 nodes) without + sacrificing performance. When loading a large dataset, the nodes are clustered initially (this may take a small while) to have a + responsive visualization to work with. The clustering is both outside-in and inside-out. Outside-in means that nodes with only one + connection will be contained, or clustered, in the node it is connected to. Inside-out clustering first determines which nodes are hubs. + Hubs are defined as the nodes with the top 3% highest amount of connections (assuming normal distribution). These hubs then "grow", meaning + they contain the nodes they are connected to within themselves. The edges that were connected to the nodes that are absorbed will be reconnected to the cluster. +
+
+ A cluster is just a node that has references to the nodes and edges it contains. It has an internal counter to keep track of its size, which is then used + to calculate the required forces. The contained nodes are removed from the global nodes index, greatly speeding up the system. +
+
+ The clustering has the following user-configurable settings. The default values have been tested with the Graph examples and work well. + The default state for clustering is off. +

NameTypeDefaultDescription
initialMaxNodesNumber100If the initial amount of nodes is larger than this value, clustering starts until the total number of nodes is less than this value.
clusterThresholdNumber500While zooming in and out, clusters can open up. Once there are more than absoluteMaxNumberOfNodes nodes, + clustering starts until reduceToMaxNumberOfNodes nodes are left. This is done to ensure performance is continuously fluid.
reduceToNodesNumber300While zooming in and out, clusters can open up. Once there are more than absoluteMaxNumberOfNodes nodes, + clustering starts until reduceToMaxNumberOfNodes nodes are left. This is done to ensure performance is continiously fluid.
chainThresholdNumber0.4Because of the clustering methods used, long chains of nodes can be formed. To reduce these chains, this threshold is used. + A chainThreshold of 0.4 means that no more than 40% of all nodes are allowed to be a chain node (two connections). + If there are more, they are clustered together.
clusterEdgeThresholdNumber20This is the absolute edge length threshold in pixels. If the edge is smaller on screen (that means zooming out reduces this length) + the node will be clustered. This is triggered when zooming out.
sectorThresholdInteger50If a cluster larger than sectorThreshold is opened, a seperate instance called a sector, will be created. All the simulation of + nodes outside of this instance will be paused. This is to maintain performance and clarity when examining large clusters. + A sector is collapsed when zooming out far enough. Also, when opening a cluster, if this cluster is smaller than this value, it is fully unpacked.
screenSizeThresholdNumber0.2When zooming in, the clusters become bigger. A screenSizeThreshold of 0.2 means that if the width or height of this cluster + becomes bigger than 20% of the width or height of the canvas, the cluster is opened. If a sector has been created, if the sector is smaller than + 20%, we collapse this sector.
fontSizeMultiplierNumber4.0This parameter denotes the increase in fontSize of the cluster when a single node is added to it.
forceAmplificationNumber0.6This factor is used to calculate the increase of the repulsive force of a cluster. It is calculated by the following + formula: repulsingForce *= 1 + (clusterSize * forceAmplification).
distanceAmplificationNumber0.2This factor is used to calculate the increase in effective range of the repulsive force of the cluster. + A larger cluster has a longer range. It is calculated by the following + formula: minDistance *= 1 + (clusterSize * distanceAmplification).
edgeGrowthNumber11This factor determines the elongation of edges connected to a cluster.
nodeScaling.widthNumber10This factor determines how much the width of a cluster increases in pixels per added node.
nodeScaling.heightNumber10This factor determines how much the height of a cluster increases in pixels per added node.
nodeScaling.radiusNumber10This factor determines how much the radius of a cluster increases in pixels per added node.
activeAreaBoxSizeNumber100Imagine a square with an edge length of activeAreaBoxSize pixels around your cursor. + If a cluster is in this box as you zoom in, the cluster can be opened in a seperate sector. + This is regardless of the zoom level.

Events

+

+ Timeline fires events when changing the visible window by dragging, or when + selecting items. +

+ +

+ Here an example on how to listen for a select event. +

+ +
+timeline.on('select', function (properties) {
+  alert('selected items: ' + properties.nodes);
+});
+
+ +

+ A listener can be removed via the function off: +

+ +
+function onSelect (properties) {
+  alert('selected items: ' + properties.nodes);
+}
+
+// add event listener
+timeline.on('select', onSelect);
+
+// do stuff...
+
+// remove event listener
+timeline.off('select', onSelect);
+
+ + +

+ The following events are available. +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + +

  • end (Number): timestamp of the current end of the window.

Clustering - Fully random graph

+
+ This example shows a fully randomly generated set of nodes and connected edges. + By clicking the checkbox you can turn clustering on and off. If you increase the number of nodes to + a value higher than 100, automatic clustering is used before the initial draw (assuming the checkbox is checked). +
+
+ Clustering is done automatically when zooming out. When zooming in over the cluster, the cluster pops open. When the cluster is very big, a special instance + will be created and the cluster contents will only be simulated in there. Double click will also open a cluster. +
+
+ Try values of 500 and 5000 with and without clustering. All thresholds can be changed to suit your dataset. +
