I am looking for hatch fill in a pie chart area. Like this

i have find hatch fill code form here
So i have to clone path attribute and give it fill:url(#diagonalHatch) .Its working if i do it manually in chrome. it shows the pattern

Now i want to clone that path and give that attr and insert it to sibling. I am trying to access that path but not successful. fiddle here . if someone had jquery solution it would be fine too. My current code
  var testdata = [
    {
      key: "eight two%",
      y: 82
    },
    {
      key: "eighteen%",
      y: 18
    }
  ];
nv.addGraph(function() {
    var width = 500,
        height = 500;
    var chart = nv.models.pieChart()
        .x(function(d) { return d.key })
        .y(function(d) { return d.y })
        .color(['red','green'])
        .width(width)
        .height(height);
      d3.select("#test1")
          .datum(testdata)
        .transition().duration(1200)
          .attr('width', width)
          .attr('height', height)
          .call(chart);
    var svg = d3.select("#test1");
    svg
            .append('defs')
            .append('pattern')
            .attr('id', 'diagonalHatch')
            .attr('patternUnits', 'userSpaceOnUse')
            .attr('width', 4)
            .attr('height', 4)
            .append('path')
            .attr('d', 'M-1,1 l2,-2 M0,4 l4,-4 M3,5 l2,-2')
            .attr('stroke', '#000000')
            .attr('stroke-width', 1);
    return chart;
});
var svg2 = d3.select("#test1");
  var node = svg2.select(".nv-slice path").attr('d');
  console.log(node);
