Appearance
Stroke
This example shows how to use the innerStroke and outerStroke attributes to change the stroke of a node.
js
import Ogma from '@linkurious/ogma';
const ogma = new Ogma({
container: 'graph-container'
});
// Define the default stroke appearance
// innerStroke is the node border
ogma.styles.addNodeRule({
innerStroke: {
color: 'black',
width: 2,
minVisibleSize: 5
}
});
// Define the stroke appearance on hover
ogma.styles.setHoveredNodeAttributes({
outerStroke: {
width: 10,
color: 'red'
}
});
// Define the stroke appearance on selection
ogma.styles.setSelectedNodeAttributes({
innerStroke: {
color: 'white'
},
outerStroke: {
width: 7,
color: 'red'
}
});
// Generate a random graph and assign it to Ogma
ogma.generate
.random({
nodes: 10,
edges: 5
})
.then(graph => {
ogma.setGraph(graph);
ogma.view.locateGraph();
});
