Chart.js-绘制带有多个标签的条形图

对于那些有类似问题的人。我需要使数据com_passed和com_failed作为数组而不是像这样的整数。

    var com_passed = rows[rows.length-2]["# Common Passed"];
    var com_failed = rows[rows.length-2]["# Common Failed"];
    var ctx = document.getElementById("common_chart");
    ctx.height = 50;

    var historicalChart = new Chart(ctx, {
        type: 'bar',
        data: {
            labels: ["Passed", "Failed"],
            datasets: [
            { 
                data: [com_passed],
                label: "Passed",
                fillColor: "red"
            },
            { 
                data: [com_failed],
                label: "Failed",
                fillColor: "green"                      
            }
                ]
        },
            options: {
                scales: {
                    yAxes: [{
                        ticks: {
                        beginAtZero:true,
                        responsive: false,
                        maintainAspectRatio: true
                        }
                    }]
                }
            }
    });
