Currently trying to create a bar chart in HTML/Javascript. Can't seem to get the bars showing for some reason. Below is the code and image..
Chart shows up but not the actual bars. Guessing this is a data issue but I've been stumped for ages. Any help is greatly appreciated!
HTML
<canvas id="myChart"></canvas>
JS
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'bar',
data: {
label: ['Red','Blue','Yellow','Green','Purple','Orange'],
datasets: [{
label: 'number of votes',
data: [1,2,3,4,5,6],
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)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'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)',
'rgba(255, 159, 64, 0.2)'
],
borderWidth: 1
}]
},
options: {
scales: {
y: {
beginAtZero: true
}
}
}
});

You have to use labels
instead of label
for the bar labels. See the official documentation: LINK
So your JS would look like this (see the change on line 5):
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ['Red','Blue','Yellow','Green','Purple','Orange'],
datasets: [{
label: 'number of votes',
data: [1,2,3,4,5,6],
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)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'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)',
'rgba(255, 159, 64, 0.2)'
],
borderWidth: 1
}]
},
options: {
scales: {
y: {
beginAtZero: true
}
}
}
});

It is a basic typo error. It should be 'labels' whereas you have written 'label'.
data: {
labels: ['Red','Blue','Yellow','Green','Purple','Orange'],
datasets: [{
