var canvassize=800;
var px=canvassize/2;
var py=canvassize/2
var l=canvassize/2;
var c=document.getElementById("prfmCanvas");
var ctx=c.getContext("2d");
var deg = Math.PI/180;
var pos_num = 360/15;
var pos = new Array(pos_num);
ctx.strokeStyle='rgb(200, 200, 200)';
for(var i=0; i < pos_num; i++ ) {
  var t0 = deg * (i*15);
  var xy = new Array(2);
  xy[0] = Math.cos(t0)*l;
  xy[1] = Math.sin(t0)*l;
  pos[i] = xy; 
}

  var xy_start = pos[i]
  for(var j=0; j < pos_num/2; j++ ) {
      ctx.moveTo(xy_start[0] + px ,xy_start[1] + py);
      t = (i + (j*2)) % pos_num ;
      var xy_end = pos[t];
      ctx.lineTo(xy_end[0] + px, xy_end[1] + py);
      ctx.stroke();
  }
