HTML and JavaScriptissue: My chart is so big

Time：06-11

I'm following a YouTube tutorial and in the video it shows this chart: enter image description here

and my chart looks like this: enter image description here

So how to solve it, as looks like the first picture?

I wrote the same exact code from the tutorial, so I don't know why I have this problem.

I tried in HTML playing with height and width to make it much smaller or bigger, for example:

<canvas id="myChart" width="100" height="100"></canvas>

<canvas id="myChart" width="200" height="200"></canvas>

<canvas id="myChart" width="400" height="400"></canvas>

Even if I changed the width and height, don't change the size

//MenuToggle
let toggle = document.querySelector('.toggle');
let navigation = document.querySelector('.navigation');
let main = document.querySelector('.main');

toggle.onclick = function() {
  navigation.classList.toggle('active');
  main.classList.toggle('active');
}

//ad hovered class in selected list item
let list = document.querySelectorAll('.navigation li');

function activeLink() {
  list.forEach((item) =>
    item.classList.remove('hovered'));
  this.classList.add('hovered');
}
list.forEach((item) =>
  item.addEventListener('mouseover', activeLink));

var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
  type: 'polarArea',
  data: {
    labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'],
    datasets: [{
      label: '# of Votes',

CodePudding user response：

chartjs canvas fills the width of the parent element. Try adding width value to the parent element of the canvas via style attribute or css. Something like:

  <div  style="width: 200px;">
    <canvas id="myChart"></canvas>

  </div>

If you are using bootstrap, you may try adding proper col classes to the parent element instead of using explicit width values so you may keep it responsive.
