bluesky,

Chart skips some of the labels to avoid overlapping. But you can force it to show all labels by setting interval property of axisX to 1. Below is the code snippet –

axisX:{
   interval: 1
}

Please take a look at this JSFiddle for a working example.

stuart,

In your csv file you have dateTime values which you are assigning to label property. Instead you should be assign dateTime values to x-value which can be done as shown below :

<!DOCTYPE html>
<html>
<head>
    <title>Test</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <script src="https://canvasjs.com/assets/script/jquery-1.11.1.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {

            var dataPoints1 = [];
            var dataPoints2 = [];

            $.ajax({
                type: "GET",
                url: "http://www.cuedup.biz/vgraphing/demoui/BT01.csv",
                dataType: "text",
                success: function (data) { processData1(data); }
            });

            function processData1(allText) {
                var allLinesArray = allText.split('\n');
                if (allLinesArray.length > 0) {
                    for (var i = 0; i <= allLinesArray.length - 2; i++) {
                        var rowData = allLinesArray[i].split(',');

                        var labelData = rowData[0].split(":");

                            labelData[2] = 0;

                        labelData[0] = parseInt(labelData[0]);

[Update]

Now we have a Tutorial on Creating Charts from JSON Data in our documentation.

Chart From JSON

Hello,

You need to create a HTML page that does AJAX request and fetch the data. After getting the data, it will render a Chart. Please refer the below mentioned code :

<html>
<head>
    <script type="text/javascript" src="https://canvasjs.com/assets/script/jquery-1.11.1.min.js"></script>
    <script type="text/javascript" src="https://cdn.canvasjs.com/canvasjs.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {

            var dataPoints = [];

            var chart = new CanvasJS.Chart("chartContainer",
            {
                    title: {
                        text: "Basic Column Chart"
                    },
                    data: [
                    {
                        dataPoints: []
                    }]
            });

            // Ajax request for getting JSON data
            //Replace data.php with your JSON API's url

            $.getJSON("data.php", function (data) {

                for (var i = 0; i < data.length; i++) {

                    dataPoints.push({ label: data[i].source, y: data[i].sourcecount });
                }

                chart.options.data[0].dataPoints = dataPoints;
                chart.render();
            });
        });
    </script>
</head>
<body>
    <div id="chartContainer" style="width: 50%; height: 300px;"></div>
</body>
</html>

This is not possible as of now. But you can consider using stackedColumn chart instead.

Without looking into your JSON data it’s hard to guess the problem so please post your JSON response here so that we can have a look ?
