我正在尝试使用Chart.Js构建图表.这个chart.js有工具提示的默认选项,我想制作自定义的工具提示选项.有没有办法让它成为可能？

这是我的代码

 var chart = null;
barChart: function (data1, data2, data3, label) {

    var data = {
        labels: label,
        datasets: [
        {
            fillColor: "rgba(220,220,220,0.5)",
            strokeColor: "rgba(220,220,220,0.8)",
            highlightFill: "rgba(220,220,220,0.75)",
            highlightStroke: "rgba(220,220,220,1)",
            data: data1
        },
         {
             fillColor: "rgba(151,187,205,0.5)",
             strokeColor: "rgba(151,187,205,0.8)",
             highlightFill: "rgba(151,187,205,0.75)",
             highlightStroke: "rgba(151,187,205,1)",
             data: data2
         },
          {
              fillColor: "rgba(0,255,0,0.3)",
              strokeColor: "rgba(220,220,220,0.8)",
              highlightFill: "rgba(220,220,220,0.75)",
              highlightStroke: "rgba(0,255,0,0.3)",
              data: data3
          },
        ]
    }
    var cht = document.getElementById('exampleCanvas');
    var ctx = cht.getContext('2d');
    if (chart)
        chart.destroy();
    chart = new Chart(ctx).Bar(data);
}
