如何在plot.ly JS中获取在图例中单击的轨迹

var trace1 = {
  x: [1, 2, 3, 4],
  y: [10, 15, 13, 17],
  type: 'scatter',
  name: 'Trace 1'
};

var trace2 = {
  x: [1, 2, 3, 4],
  y: [16, 5, 11, 9],
  type: 'scatter',
  name: 'Trace 2'
};

var data = [trace1, trace2];

var layout = {
  title: 'Plotly Legend Click Event',
  showlegend: true
};

Plotly.newPlot('myDiv', data, layout);

var myPlot = document.getElementById('myDiv');

myPlot.on('plotly_legendclick', function(data) {
  var clickedTrace = data.curveNumber;
  var traceName = data.data[clickedTrace].name;
  
  console.log('Clicked Trace:', traceName);
});
