[Solved]-D3 Radar Chart Colors-d3.js

if you want to set your own colors based on series order:

  var mycfg = {
    color: function(i) {
      c = ['red', 'yellow', 'pink', 'green', 'blue', 'olive', 'aqua', 'cadetblue', 'crimson'];
      return c[i];
    }
  }

the first series will be red, second yellow, etc...
