Cannot read property 'format' of undefined #243
Description
I currently want to write a chrome app that contains a epoch graph.
Heres my index.html:
<html>
<head>
<meta charset="utf-8">
<title>Test</title>
<link href="styles/main.css" rel="stylesheet">
<link rel="stylesheet" type="text/css" href="css/epoch.min.css">
</head>
<body>
<h1>Test</h1>
<div id="pie" style="width: 400px; height: 400px"></div>
<script src="js/d3.js"></script>
<script src="js/epoch.js"></script>
</body>
</html>
Heres my main.js:
chrome.app.runtime.onLaunched.addListener(function() {
var screenWidth = screen.availWidth;
var screenHeight = screen.availHeight;
var width = 500;
var height = 300;
chrome.app.window.create('index.html', {
id: "helloWorldID",
outerBounds: {
width: width,
height: height,
left: Math.round((screenWidth-width)/2),
top: Math.round((screenHeight-height)/2)
}
});
});
var pieData = [
{ label: 'Slice 1', value: 10 },
{ label: 'Slice 2', value: 20 },
{ label: 'Slice 3', value: 40 },
{ label: 'Slice 4', value: 30 }
]
$('#pie').epoch({
type: 'pie',
data: pieData
});
When I run this, the chart area stays empty and the error "Uncaught TypeError: Cannot read property 'format' of undefined" appears. The line the error occurs at is 429 which contains this:
d3Seconds = d3.time.format('%I:%M:%S %p');
My guess is that the error appears because d3 wasnt properly loaded but I dont know how to fix this as I think I followed the guide.
