      $(function () {

      var d1 = [];
      for (var i = 0; i < = 10; i += 1) d1.push([i, parseInt(Math.random() * 30)]); var d2 = []; for (var i = 0; i <= 10; i += 1) d2.push([i, parseInt(Math.random() * 30)]); var ds = new Array(); ds.push({ data:d1, bars: { show: true, barWidth: 0.2, order: 1, lineWidth : 2, color : #ff0000
      bars: {

    Hi, this is an excellent plugin but it doesn’t allow to change colors.
    I’ve seen the answer above but no luck, I’ve tested it with the same from this demo and doesn’t work.

    I hope you can find a workaround for this or add a pretty simple demo with other colors to use as a reference.

    Thanks and keep up the good work!
