Efficiently assign multiple attributes using a single d3 function

Hey everyone! I'm currently working with SVG lines and have come across an example object that looks like this:

{
  _id: 5,
  coordinates:{
       x1: 100,
       y1: 100,
       x2: 500,
       y2: 500,
 }

Now, imagine I have an array of these objects stored in a variable called data. My goal is to set all the relevant line attributes in just one attr() call. I know that you can pass an object as an attribute, allowing d3 to set all attributes accordingly. Since I have an array of objects, I decided to create a function that returns the object:

let objectsRender = svg.selectAll("line")
                       .data(data)
                       .enter()
                       .append("line")
                       .attr(function(d)      { return d.coordinates;})
                       .attr("id", function(d){ return prefix +d._id;});

However, it seems like this approach isn't working for me since none of the x or y values are being set. Could anyone help me find a solution to this issue?

Answer №1

Unfortunately, accomplishing this task in just one line is not possible. You will need to follow these steps:

.attr({
    x1: function (d) { return d.coordinates.x1; },
    x2: function (d) { return d.coordinates.x2; },
    y1:  function (d) { return d.coordinates.y1; },
    y2:  function (d) { return d.coordinates.y2; }
  });
