cytoscape-lasso

Lasso selection plugin for Cytoscape

Demo

Lasso selection is implemented using public Cytoscape API, rendering lasso polygon to a new topmost separate canvas.

Lasso polygon style can be controlled by box selection style properties:

• selection-box-color
• selection-box-border-color
• selection-box-border-width
• selection-box-opacity

Box selection core events and collection events are fired:

• boxstart
• boxend
• boxselect
• box
• select
• unselect

Compatible with Cytoscape plugins:

• cytoscape-edgehandles
• cytoscape-mapbox-gl

Install

npm install cytoscape-lasso

or

<script src="https://unpkg.com/[email protected]/dist/cytoscape-lasso.min.js"></script>

Usage

The plugin exposes a single function, which should be used to register the plugin to Cytoscape.js.

import cytoscape from 'cytoscape';
import cytoscapeLasso from 'cytoscape-lasso';

cytoscape.use(cytoscapeLasso);

Plain HTML/JS has the extension registered for you automatically.
