Is there a bug with Chart.js? Every time I add any of the graphs at Chart.js to my website I get an error, but when I used the graph as stand-alone program it runs smoothly without errors. I am using HTML5.
<html>
<head>
<meta charset="utf-8" />
<title>Rice Consumption</title>
<script src='Chart.min.js'></script>
</head>
<body>
<canvas id="rice" width="600" height="400"></canvas>
<script>
var riceData = {
labels : ["January","February","March","April","May","June"],
datasets :
[
{
fillColor : "rgba(172,194,132,0.4)",
strokeColor : "#ACC26D",
pointColor : "#fff",
pointStrokeColor : "#9DB86D",
data : [203000,15600,99000,25100,30500,24700]
}
]
}
var rice = document.getElementById('rice').getContext('2d');
new Chart(rice).Line(riceData);
</script>
</body>
</html>
SOLVED: I just decoupled the script from the canvas element (made another file for the script to execute its function).
Updated HTML:
<html>
<head>
<meta charset="utf-8" />
<title>Rice Consumption</title>
<script src='Chart.min.js'></script>
</head>
<body>
<canvas id="rice" width="600" height="400"></canvas>
<script src='Chart.min.js'></script>
<script src='rice.js'></script>
</body>
</html>
New JavaScript file:
var riceData = {
labels : ["January","February","March","April","May","June"],
datasets : [
{
fillColor : "rgba(172,194,132,0.4)",
strokeColor : "#ACC26D",
pointColor : "#fff",
pointStrokeColor : "#9DB86D",
data : [203000,15600,99000,25100,30500,24700]
}
]
}
var rice = document.getElementById('rice').getContext('2d');
new Chart(rice).Line(riceData);

I was also getting same error. To fix this I moved the chart script into separate graph.js file.
Still I was getting same error. Which is fixed later when I put tag in following order before end of tag as shown below.
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.4.0/Chart.min.js"></script>
<script type="text/javascript" src="jscript/graph.js"></script>
</body>
The page look like this:
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
}
}]
}
}
});<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.4.0/Chart.min.js"></script>
<!DOCTYPE html>
<canvas id="myChart"></canvas>here is a working jsfiddle of your code: new Chart(rice).Line(riceData);

So the problem is definitively coming from your external Chart.min.js inclusion
You may find a 404 on your js get. Please make sure you're linking to the correct js folder. (try accessing your localhost/Chart.min.js to see if you can access to your file)
