Update Item's Style

1 min read

There are three ways to modify the styles for items in G6.

Configure When Instantiating Graph

When instantiating a Graph, assign style in defaultNode or defaultEdge to configure the styles for global nodes and global edges respectively.

const graph = new G6.Graph({
  container: 'mountNode',
  width: 1000,
  height: 800,
  defaultNode: {
    shape: 'circle',
    style: {
      fill: '#fff',
      fontSize: 14,
    },
  },
  defaultEdge: {
    shape: 'line-with-arrow',
    style: {
      fill: '#fff',
      fontSize: 14,
    },
  },
});

Configure style in Data

const data = {
  nodes: [
    {
      id: 'node1',
      label: 'node1',
      style: {
        fill: '#fff',
        fontSize: 12,
      },
    },
  ],
};

update / updateItem

graph.updateItem(node, {
  // The node style
  style: {
    stroke: 'blue',
  },
});

For more information about the styles, refer to Node Style Properties.
