Possible reasons why Chart.js is not displaying output within a Bootstrap block

The chart on page chart.html isn't displaying the bar graph as intended. The expected output can be found at https://www.chartjs.org/docs/latest/getting-started/

Content of chart.html:

{% extends "base.html" %}

{% block js %}
    <div>
      <canvas id="myChart"></canvas>
    </div>
    <script src="../static/js/try.js"></script>
{% endblock %}

Inside try.js:

import 'https://cdn.jsdelivr.net/npm/chart.js';
const ctx = document.getElementById('myChart');

new Chart(ctx, {
    type: 'bar',
    data: {
        labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'],
        datasets: [{
            label: '# of Votes',
            data: [12, 19, 3, 5, 2, 3],
            borderWidth: 1
        }]
    },
    options: {
        scales: {
            y: {
                beginAtZero: true
            }
        }
    }
});

Answer №1

An error occurred while attempting to import in the file try.js.

To fix this issue, it is advised to move the import statement to the file chart.html.

Within the file chart.html:

{% extends "base.html" %}

{% block js %}
    <div>
      <canvas id="myChart"></canvas>
    </div>
    <script src="https://cdn.jsdelivr.net/npm/chart.js"></script>
    <script src="../static/js/try.js"></script>
{% endblock %}

I have personally tested and confirmed that implementing this adjustment resolved the problem.
