[Solved]-d3 radar chart -- radialLine creates path but without coordinates-d3.js

I've edited your fiddle a bit to make it work:

https://jsfiddle.net/2qgygksL/75/

Basicly what i've done:

fix the color scheme

var colors = d3.scale.category10();

instead of

var colors = d3.scale.ordinal(d3.schemeCategory10);

added data to path

radarWrapper.append("path")
          .data(scaledData)

change radius to

  .radius(function(d, i) {
        return d;
  })

since You used something like return scaledData(d.value); where your scaledData is an array.
