如何使用chart.js在点悬停中显示多个值

我想知道如果可以在chart.js中显示更多的点悬停值.

看看这个小提琴.这是一个取自chart.js网站的smiple图示例.如果我悬停一个点,它会显示数据集值.

我怎样才能展示其他价值.喜欢这个阵列.

[65, 59, 80, 81, 56, 55, 40]

如果我想显示这个数组值 [1, 2, 3, 4, 5, 6, 7].就像我想要显示编号.这只是一个例子,实际上我想显示更多的两个值,但不想在图表上仅在pointhover中显示它.就像在65上一样,它告诉它是第1个值.

任何形式的帮助将不胜感激.

是的,请使用工具提示选项,如下所示

var ctx = document.getElementById('chart1').getContext("2d");
    var data = {
    labels: ["January", "February", "March", "April", "May", "June", "July"],
    datasets: [
        {
            label: "My First dataset",
            fill: false,
            lineTension: 0.1,
            backgroundColor: "rgba(75,192,192,0.4)",
            borderColor: "rgba(75,192,192,1)",
            borderCapStyle: 'butt',
            borderDash: [],
            borderDashOffset: 0.0,
            borderJoinStyle: 'miter',
            pointBorderColor: "rgba(75,192,192,1)",
            pointBackgroundColor: "#fff",
            pointBorderWidth: 1,
            pointHoverRadius: 5,
            pointHoverBackgroundColor: "rgba(75,192,192,1)",
            pointHoverBorderColor: "rgba(220,220,220,1)",
            pointHoverBorderWidth: 2,
            pointRadius: 1,
            pointHitRadius: 10,
            data: [65, 59, 80, 81, 56, 55, 40],
            spanGaps: false,
        }
    ]
};

                           multistringText.push('Another Item');
                           multistringText.push(tooltipItems.index+1);
                           multistringText.push('One more Item');
                        return multistringText;
