Appearance
Background
This example shows how to use the backgroundColor attribute on nodes and edges texts.
ts
import Ogma from '@linkurious/ogma';
const ogma = new Ogma({
container: 'graph-container'
});
ogma.styles.addNodeRule({
radius: 3,
color: '#1499ff',
text: {
content: n => 'Node ' + n.getId(),
color: '#000',
backgroundColor: 'inherit', // values: named, hex, rgb, rgba, 'inherit' (will inherit node color)
padding: 3,
minVisibleSize: 5,
margin: 20
}
});
ogma.styles.setHoveredNodeAttributes({
text: {
color: '#fff',
backgroundColor: '#000'
}
});
ogma.styles.setSelectedNodeAttributes({
text: {
color: '#fff',
backgroundColor: '#000'
}
});
ogma.styles.addEdgeRule({
color: '#ccc',
text: {
content: e => 'Edge ' + e.getId(),
color: '#fff',
backgroundColor: 'inherit', // values: named, hex, rgb, rgba, 'inherit' (will inherit node color)
minVisibleSize: 3,
padding: 2
}
});
ogma.styles.setHoveredEdgeAttributes({
text: {
color: '#fff',
backgroundColor: '#000'
}
});
ogma.styles.setSelectedEdgeAttributes({
text: {
color: '#fff',
backgroundColor: '#000'
}
});
const graph = await ogma.generate.random({ nodes: 6, edges: 6 });
await ogma.setGraph(graph);
await ogma.view.locateGraph();
