Node JS和Chart JS数据可视化

Question

我的问题是从mysql数据库中获取数据后，我可以将数据传递到前端，但是即使我尝试了许多解决方案，也无法在js图表图形中使用这些数据。谁能给我分享链接或提供有关该问题的示例？

chartdesign.js

 new Chart(document.getElementById("myChart"), {
      type: 'bar',
      data: {
        labels: ["Africa", "Asia", "Europe", "Latin America", "North America"],
        datasets: [
          {
            label: "Population (millions)",
            backgroundColor: ["#3e95cd", "#8e5ea2","#3cba9f","#e8c3b9","#c45850"],
            data: [] // I want to add data here
          }
        ]
      },
      options: {
        legend: { display: false },
        title: {
          display: true,
          text: 'Predicted world population (millions) in 2050'
        }
      }
  });

graphPage.hbs

<div class="card-group" style="margin-top: 50px; margin-bottom: 50px;">


<!-- Graphs -->

<div class="card-columns" style="margin-top:50px;">


<div class="card border-light"  data-placement="top"  style=" background-color:white;">


<div class="card-body">

    <canvas id="myChart" width="400" height="300"></canvas>
    </div>
</div>

</div>

app.js

 config.query('//select query part',(err,ornek)=>{

        if(err){
          res.send('/404.html');
        }
        else{ 

        req.session.ornek= ornek;
        res.render('graphPage',{user: req.session.fullname, ornek: req.session.ornek});

        }
      });
