Dygraph troubleshoot CSV

This is straight from dygraphs under the Error Bars section and I have the csv file in the same dir as the html with the dygraph code. Neither Firefox or Chrome throw an error or draw any lines. It only displays the axis and background grid. How do I go about chasing this down?
Is the .csv file getting loaded ? Where should I start looking, in dygraph-combined.js?

<html>
<head>
<script type="text/javascript" src="js/dygraph-combined.js"></script>
</head>
<body>
<div id="graphdiv4" style="width:480px; height:320px;"></div>
<script type="text/javascript">
  g4 = new Dygraph(
    document.getElementById("graphdiv4"),
    "twonormals.csv",
    {
      rollPeriod: 7,
      showRoller: true,
      errorBars: true,
      valueRange: [50,125]
    }
  );
</script>
</body>
</html>
Solution

  • Make sure that twonormals.csv is world-readable. Can you view/download it by typing its URL directly in the URL bar?
