I am not very experienced with JavaScript and have a bit of difficulty with chart.js I can't get the chart.js graph to appear. I've tried everything, but nothing; below I have left you a part of the code and the photo of how the "graph" looks. Thanks in advance
<h5 class="card-title">Line Chart</h5>
<div style="height: 400px">
<canvas id="line-char"></canvas>
<script>
const ctx = document.getElementById('myChart');
const ctx = document.getElementById('myChart').getContext('2d');
const ctx = $('#myChart');
const ctx = 'myChart';
</script>
<canvas id="line-char"></canvas>
<script>
const ctx = document.getElementById('line-char');
const line_char = new Chart(ctx, {
type: 'bar',
data: {
labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',

'rgba(153, 102, 255, 0.2)',
'rgba(255, 159, 64, 0.2)'

'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)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1
}]
},
options: {
scales: {
y: {
beginAtZero: true
}
}
}
});
</script>
Your chart configuration contains invalid characters in backgroundColor and borderColor (‘ instead of ').
‘rgba(75, 192, 192, 0.2)',
Please take a look at your amended and runnable code below and see how it works now.
