我试图删除从图表工具提示的颜色标签平方米。我怎样才能让这段代码中发生的与机智的所有其他代码？

var ctx = document.getElementById("myChart");
var myChart = new Chart(ctx, {
type: 'line',
data: {
datasets: [{
data: [], //start empty backgroundColor: '#e8ebf8', borderColor: '#615BD4', borderWidth: 1 }] }, options: { scales: { yAxes: [{ ticks: { display: false, beginAtZero: true } }], xAxes: [{ ticks: { stepSize: 2, maxTicksLimit: 90 } }] }, legend: { display: false }, tooltips: { intersect: false, showTooltips: true, tooltipEvents: ["mousemove", "touchstart", "touchmove"], tooltipFillColor: "rgba(0,0,0,0.8)" } } }); window.onmessage = function(event) { myChart.data.datasets[0].data = event.data.data; myChart.data.labels = event.data.labels; myChart.update(); }; function handleClick(e) { var activeBars = myChart.getElementAtEvent(e); var value = myChart.config.data.datasets[activeBars[0]._datasetIndex].data[activeBars[0]._index]; var label = activeBars[0]._model.label; window.parent.postMessage({ "type": "click", // "label":label, "value": value }, "*"); } function ready() { window.parent.postMessage({ "type": "ready" }, "*"); }
</script>

使用回调功能删除标签：
options: {
legend: {
display: false
},
tooltips: {
callbacks: {
label: function(tooltipItem) {
console.log(tooltipItem)
return tooltipItem.yLabel;
}
}
}
}
