google-visualization - 在 Sankey 图表中按名称排序

Question

是否可以使用 sankey 按名称排序？例如:

示例: https://jsfiddle.net/Khrys/1s3shf2m/

  google.setOnLoadCallback(drawChart);

  function drawChart() {
    var data = new google.visualization.DataTable();
    data.addColumn('string', 'From');
    data.addColumn('string', 'To');
    data.addColumn('number', 'Weight');
    data.addRows([
      [ 'A', 'Mango', 5 ],
      [ 'A', 'Mango', 7 ],
      [ 'A', 'Apple', 6 ],
      [ 'B', 'Coconut', 2 ],
      [ 'B', 'Mango', 9 ],
      [ 'B', 'Pineapple', 4 ]
    ]);

    // Sets chart options.
    var options = {
      width: 600,
    };

    // Instantiates and draws our chart, passing in some options.
    var chart = new google.visualization.Sankey(document.getElementById('sankey_basic'));
    chart.draw(data, options);
  }

我期望右侧的输出是(从上到下):Apple、Coconut、Mango、Pineapple

谢谢

将迭代次数设置为0，图表应根据数据的输入顺序绘制。

例子:

var options = {
  height: 400,
  width: 400,
  sankey: {
iterations: 0,
      }
