我尝试将6个不同的数据集组组合在一起，因此我有一个“-15”数据集、“15”数据集等的切换。x1c 0d1x
以下是我目前掌握的情况：

var labels = [];
    for (let index = 0; index < 12; index++) {
        labels.push(index);
    }

        window.onload = function () {
            var canvas = document.getElementById('elm-chart'),
            ctx = canvas.getContext('2d');

            var myLineChart = new Chart(ctx, {
                type: 'line',
                data: {
                    labels: labels,
                    datasets: [
                {
                    label: '-15',
                    data: [
                        {
                            x: 0,

                        },
                        {
                            x: 1,
                            y: 20,

从我目前为止读到的文档来看，我找不到任何可以直接编辑图例的东西，只能切换隐藏或不隐藏。没有任何关于编辑图例列表的东西
