Update pie chart Chart.js with select

[polloshermanos9]

I have a pie chart that updates depending on the option selected by the user. When I click the option "All" the graph updates correctly but when you click individual options the graph does not show what it should.

orders = [
  { name: 'Luis', orders_by_user: 25.5 },
  { name: 'Jose', orders_by_user: 16.3 },
  { name: 'Miguel', orders_by_user: 3.8 }
];

const myChart = new Chart(document.getElementById('orders'), {
  type: 'pie',
  data: {
    labels: orders.map(o => o.name),
    datasets: [{
      label: 'Terminadas',
      data: orders.map(o => o.orders_by_user),
      borderColor: 'rgba(75, 192, 192, 1)',
      backgroundColor: "#229954",
      borderWidth: 1,

    }]
  },
  options: {
    title: {
      display: true,
      text: "Ordenes en estado terminado"
    },
    },
    
 
  
});

orders.forEach(o => {
  const opt = document.createElement('option');
  opt.value = o.name;
  opt.appendChild(document.createTextNode(o.name));
  document.getElementById('operator').appendChild(opt);
});

function refreshChart(name) {
  myChart.data.labels = [name];
  if (name == 'All') {
     myChart.data.labels = orders.map(o => o.name),
     myChart.data.datasets[0].data = orders.map(o => o.orders_by_user);
  } else {
    myChart.data.labels = [name];
    myChart.data.datasets[0].data = orders.find(o => o.name == name).orders_by_user;
  }
  myChart.update();
}

And this is mi html code

Operarios:
<select id="operator" onchange="refreshChart(this.value)">
    <option>All</option>                                                            
</select>

<canvas id="orders" height="90"></canvas>

data needs to be an array. You are passing single value.

when data is an array the problem is not solved

As @kurkle pointed out the data field needs to be an array, if you make it an array it works perfectly fine: https://jsfiddle.net/Leelenaleee/x2crj0u5/3/

yes, with an array works perfectly fine. Thanks!
