What are some examples of using Chart.js?

Chart.js is a popular JavaScript library for creating charts. You can create line charts, bar charts, pie charts, and more.

Can you show me a simple line chart example?

Sure! Here's a basic example of a line chart:

const ctx = document.getElementById('myChart').getContext('2d');
const myChart = new Chart(ctx, {
    type: 'line',
    data: {
        labels: ['January', 'February', 'March', 'April', 'May'],
        datasets: [{
            label: 'Sales',
            data: [12, 19, 3, 5, 2],
            borderColor: 'rgba(75, 192, 192, 1)',
            borderWidth: 1
        }]
    },
    options: {
        scales: {
            y: {
                beginAtZero: true
            }
        }
    }
});

What about a bar chart?

Here's a simple bar chart example:

const ctx = document.getElementById('myBarChart').getContext('2d');
const myBarChart = new Chart(ctx, {
    type: 'bar',
    data: {
        labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple'],
        datasets: [{
            label: '# of Votes',
            data: [12, 19, 3, 5, 2],
            backgroundColor: [
                'rgba(255, 99, 132, 0.2)',
                'rgba(54, 162, 235, 0.2)',
                'rgba(255, 206, 86, 0.2)',
                'rgba(75, 192, 192, 0.2)',
                'rgba(153, 102, 255, 0.2)'
            ],
            borderColor: [
                'rgba(255, 99, 132, 1)',
                'rgba(54, 162, 235, 1)',
                'rgba(255, 206, 86, 1)',
                'rgba(75, 192, 192, 1)',
                'rgba(153, 102, 255, 1)'
            ],
            borderWidth: 1
        }]
    },
    options: {
        scales: {
            y: {
                beginAtZero: true
            }
        }
    }
});
