I want to use ChartJS so I can display charts on my website, but I don't want the JavaScript to be separate from the html. I am using pug (jade) as my view engine which I know is working properly.
First I linked ChartJS in my index.pug file and created my canvas:
html
head
link(rel='stylesheet', href='/stylesheets/styles.css', type='text/css')
script(type="text/javascript", src='https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.6.0/Chart.bundle.min.js')
script(type="text/javascript", src='/javascripts/chart.js')
title= title
body
h1= message
canvas#myChart(width='400', height='400')
Next, In my chart.js file I did:
var ctx = document.getElementById("myChart").getContext('2d');
var 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],
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(255,99,132,1)',
'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: {
yAxes: [{
ticks: {
beginAtZero:true
}
}]
}
}
});
For some reason, the chart isn't being displayed, however if I use script tags and put the JavaScript directly in the pug file it works fine. I know that the JavaScript file is being linked correctly because I checked it using an alert. Any ideas on why my chart isn't being displayed?
