How to get the node's offset values after layout get arranged in React Diagram?

This article explains how to get a node’s offset values after the layout is arranged in React Diagram. In React Diagram, support is provided to auto-arrange the nodes in the diagram area, which is referred to as Layout. Refer to this documentation to learn more about layout.

It includes the following layout modes, such as:

• Hierarchical layout
• Organization chart
• Radial tree
• Symmetric layout
• Mind Map layout
• Complex hierarchical tree layout

We can retrieve the values of the offsetX and offsetY properties of the nodes from the diagram’s nodes collection after the layout has been arranged in the diagram. In the below sample, upon clicking the button, we iterate through the nodes collection, retrieve the offsetX and offsetY values of each node, and print them in the console. For more information, please refer to the code snippet and sample link below:

//Button
 <input type="button" id="getOffset" value="get-offset-values" />
 
//method to hook on clicking the button
  document.getElementById('getOffset').onclick = (args) => {
     for (let i = 0; i < diagramInstance.nodes.length; i++) {
       console.log(
         'Node' +
           (i + 1) +
           ':' +
           'OffsetX->' +
           diagramInstance.nodes[i].offsetX
       );
       console.log(
         'Node' +
           (i + 1) +
           ':' +
           'offsetY->' +
           diagramInstance.nodes[i].offsetY
       );
     }
   };
