我使用Chart.js创建图表的垂直条。我想显示3个开发人员在特定时间内开发的代码数量。我想通过三种不同的颜色来区分这三个开发人员。就像这样...

import { Chart } from "chart.js/auto";

(async function () {
const data = [
{
  filename: "center.js",
  developer: ["John"],
  lastedit: "01-01-2022",
  lines: [40],
 },
 {
  filename: "collide.js",
  developer: ["Alex"],
  lastedit: "15-02-2022",
  lines: [70],
  },
  {
  filename: "constant.js",
  developer: ["Bob"],
  lastedit: "25-02-2022",
  lines: [10],
  },
  {
  filename: "index.js",
  developer: ["Alex"],
  lastedit: "17-03-2022",
  lines: [8],
  },
  {
  filename: "jiggle.js",
  developer: ["Bob"],
  lastedit: "19-03-2022",
  lines: [5],
  },
  {
  filename: "link.js",
  developer: ["Bob", "Alex", "John"],
  lastedit: "29-03-2022",
  lines: [120],
  },
  {
  filename: "manyBody.js",
  developer: ["Bob", "John"],
  lastedit: "09-04-2022",
  lines: [180],
  },
  {
  filename: "simulation.js",
  developer: ["Alex", "Bob", "John"],
  lastedit: "01-05-2022",
  lines: [140],
  },
  {
  filename: "x.js",
  developer: ["Bob"],
  lastedit: "03-05-2022",
  lines: [80],
  },
  ];

 new Chart(document.getElementById("acquisitions"), {
  type: "bar",
  data: {
    labels: data.map((row) => row.lastedit),
    datasets: [
    {
      label: "The amount of codes",

      data: data.map((row) => row.lines),

      backgroundColor: ["#f38b4a", "#56d798", "#6970d5"],
    },
    ],
   },
   });
  })();

我的目标是，此图表中每个条形的颜色可以根据3个不同的开发人员名称而变化。那么，我们如何为背景颜色提供一个假设？
