d3 v4从对象_data_访问x和y值

Question

dx and dy inside the transform attribute return 'undefined'.

   this.nodeElements = this.nodeGroup.selectAll('circle')
  .data(this.sensors);

console.log(this.sensors[0].x); // this returns the correct x value


const nodeEnter = this.nodeElements
  .enter()
  .append('svg:g')
  .attr('transform', d => 'translate(' + d.x + ', ' + d.y + ')');

• how can I get the defined dx or dy ? Thank you in advance.
