如何在ChartJS中为特定数据集禁用工具提示

我显示了包含两种类型的图表。现在，我想隐藏一个数据集的工具栏。我在GitHub上看到了类似的讨论，但是这并没有使我进一步。

这是我的图表的示例：

Chart.defaults.global.legend.display = false;
var ctx = document.getElementById("chart").getContext("2d");
var data = {
  labels: ["Januar","Februar","März","April","Mai","Juni","Juli","August","September","Oktober","November","Dezember"],
  datasets: [
     {
       label: "Test",
       type: 'bar',
       backgroundColor: "#F29220",
       borderColor: "#F29220",
       data: [4,1,1,2,2,2,2,2,2,2,2,1]
     },
     {
       label: "Test2",
       type: 'bar',
       backgroundColor: "#F29220",
       borderColor: "#F29220",
       data: [4,0,0,0,0,0,0,0,0,0,0,0]
     },
     {
       label: "",
       type: 'line',
       fillColor: "rgba(220,220,220,0)",
       pointColor: "rgba(220,220,220,0)",
       borderColor: "#FF0000",
       tooltip: false,
       data: [100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100, 100]
     }]
  };
  var myBarChart = new Chart(ctx, {
    type: 'bar',
    data: data,
    options: {
       scales: {
          xAxes: [{
             stacked: true,
             ticks: {
                fontColor: '#000',
             }
          }],
          yAxes: [{
             stacked: true,
             ticks: {
                beginAtZero: true,
                fontColor: '#000',
                callback: function(label, index, labels) {
                   return label + '%';
                }
             },
          }]
       },
       elements: {
          point:{
             radius: 0
          }
       },
       tooltips: {
          enabled: true,
          mode: 'single',
          callbacks: {
             label: function(tooltipItems, data) {
                 return data.datasets[tooltipItems.datasetIndex].label + ': ' + tooltipItems.yLabel + ' %';
          }
       }
    }
 }
 });

tooltips: {
    filter: function (tooltipItem) {
        return tooltipItem.datasetIndex === 0;
    }
}
