如何在chartjs2中用不同的颜色画一条线？

// 引入chartjs2库
import Chart from 'chart.js';

// 创建canvas元素
const canvas = document.getElementById('myChart');

// 定义数据集数组
const datasets = [
  {
    label: 'Line 1',
    data: [10, 20, 30, 40, 50],
    borderColor: 'red',
    backgroundColor: 'rgba(255, 0, 0, 0.2)'
  },
  {
    label: 'Line 2',
    data: [50, 40, 30, 20, 10],
    borderColor: ['blue', 'green', 'yellow', 'purple', 'orange'],
    backgroundColor: ['rgba(0, 0, 255, 0.2)', 'rgba(0, 128, 0, 0.2)', 'rgba(255, 255, 0, 0.2)', 'rgba(128, 0, 128, 0.2)', 'rgba(255, 165, 0, 0.2)']
  }
];

// 创建图表的配置对象
const config = {
  type: 'line',
  data: {
    datasets: datasets
  }
};

// 创建图表实例并渲染到canvas元素中
const myChart = new Chart(canvas, config);
