如何将单词和数字放入用CanvasJ制作的图表的条形图中？

var canvas = document.getElementById("myCanvas");
var ctx = canvas.getContext("2d");

var data = [
  { label: "单词1", value: 10 },
  { label: "单词2", value: 20 },
  { label: "单词3", value: 15 },
  // 其他单词和对应的数字
];

var barWidth = canvas.width / data.length;
var barSpacing = 10;

data.forEach(function(item, index) {
  var x = index * (barWidth + barSpacing);
  var y = canvas.height - item.value; // 条形的高度根据数值确定
  var barHeight = item.value;

  // 绘制条形
  ctx.fillStyle = "blue";
  ctx.fillRect(x, y, barWidth, barHeight);

  // 绘制单词标签
  ctx.fillStyle = "black";
  ctx.font = "12px Arial";
  ctx.fillText(item.label, x, canvas.height - 5);
});
