Bit late but I had the same problem. To fix it you need to get your chart to generate from window.onload.
e.g.
window.onload = function() {
var ctx = document.getElementById('myChart').getContext('2d');
window.myLine = new Chart(ctx, {
type: 'line',
data: {
labels: ["2010", "2011", "2012", "2013", "2014", "2015", "2016", "2017"],
datasets: [{
label: 'Udvikling i motorvejstrafikken 2010-2017',
data: [100, 103.5, 107.2, 110.3, 115.4, 120.9, 126.3, 131.5],
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: 4
}]
},
options: {
scales: {
yAxes: [{
ticks: {
min: 90
}
}]
}
}
});
};
Don’t know why it works locally without this, but needed this change to display on the server.
