Position
This example shows how to use the text position attribute to change the position of the text on nodes.
ts
import Ogma, { TextPosition } from '@linkurious/ogma';
const POSITION: TextPosition[] = ['center', 'left', 'top', 'right', 'bottom'];
const ogma = new Ogma({
container: 'graph-container',
graph: {
nodes: [
{ id: 0, attributes: { x: 0, y: 0 } },
{ id: 1, attributes: { x: 40, y: 0 } },
{ id: 2, attributes: { x: 80, y: 0 } },
{ id: 3, attributes: { x: 120, y: 0 } },
{ id: 4, attributes: { x: 160, y: 0 } }
]
}
});
ogma.styles.addRule({
nodeAttributes: {
text: {
position: node => POSITION[+node.getId()],
content: node => 'Node ' + node.getId(),
minVisibleSize: 0
}
}
});
