Network - rendering

Handles the rendering aspect of vis. It governs the render loop, it draws the nodes and edges and provides events to allow users to hook into the drawing.

Options

This is a list of all the methods in the public API. They are collected here from all individual modules.

hideNodesOnDragBooleanfalseWhen true, the nodes are not drawn when dragging the view. This can greatly speed up responsiveness on dragging, improving user experience.

Methods

This is a list of all the methods in the public API. Options can be set directly to the module or you can use the setOptions method of the network itself and use the module name as an object name.

Events

These events are fired by the renderer and can be used to move and draw custom elements on the same canvas as the rest of the network.

namepropertiesdescription
initRedrawnoneFired before the redrawing begins. The simulation step has completed at this point. Can be used to move custom elements before starting drawing the new frame.
beforeDrawingcanvas contextFired after the canvas has been cleared, scaled and translated to the viewing position but before all edges and nodes are drawn. Can be used to draw behind the network.
initRedrawcanvas contextFired after drawing on the canvas has been completed. Can be used to draw on top of the network.
