Chart.js无法创建图表 [英] Chart.js unable to create chart

问题描述

我正在尝试使用Chart.js创建一个简单的条形图，但是每次尝试呈现它时，都会出现以下错误:无法创建图表:无法从给定项目中获取上下文.

I'm trying to create a simple bar chart using Chart.js, but every time I try to render it, it give me the following error: Failed to create chart: can't acquire context from the given item.

  var hashtags = ["activewear", "adidas", "aloyoga", "batterseapark", "outdoors", "park", "training", "winter", "workout", "workoutwednesday"]
var avg_likes = [1185, 5311, 5521, 1713, 949, 321, 2860, 2661, 18899, 8108]

var chart = document.getElementById("chart");
var myBarChart = new Chart(chart, {
  type: 'bar',
  data: {
    labels: hashtags,
    datasets: [{
      data: avg_likes
    }]
  },
  options: {}
});

<div id="chart"></div>
