Highcharts Error #14 with SPServices

Question

I'm new to both highcharts and jQuery and I'm experiencing problems displaying the data from a Sharepoint list using SPServices. I have two columns; one with a Date value, and another with numeric values. I'm using tutorial this as my guideline for the code.

I'm getting the error 'Uncaught Highcharts error #14: www.highcharts.com/errors/14', which I understand is because Highcharts is expecting the Date value to be a number. I read here that I should use parseFloat() or parseInt() which has not worked.

I then tried to generate a line chart using a 'Number' type column instead of the date column and I'm receiving the same error which confuses me further. Thanks for any help.

Code:

<script>
$(document).ready(function () {

    var valuesArray = [];
    $().SPServices({
        operation: "GetListItems",
        async: false,
        CAMLQuery: "<Query><OrderBy><FieldRef Name='Week'/></OrderBy></Query>",
        listName: "{GUIDVALUEREMOVED}",
        CAMLViewFields: "<ViewFields><FieldRef Name='Week'/><FieldRef Name='Total'/></ViewFields>",
        completefunc: function (xData, Status) {
            $(xData.responseXML).SPFilterNode("z:row").each(function () {  
                var week = ($(this).attr('ows_Week'));             
                var total = ($(this).attr('ows_Total'));
                valuesArray.push([parseFloat(week), total]);      
            });
        }
    });
    chart = new Highcharts.Chart({

        chart: {
            renderTo: 'CHANGEME',
            type: 'line'
        },
        title: {
            text: 'FS Total by Week'
        },
        yAxis: {
            title: {
                text: 'values'
            },
            plotLines: [{
                value: 0,
                width: 1,
                color: '#808080'
            }]
        },
        subtitle: {
            text: 'Change me 2'
        },

        tooltip: {
            formatter: function() {
                return '<b>'+ this.y;}
        },
        credits: {
            enabled: false
        },
        plotOptions: {
            column: {
                allowPointSelect: true,
                pointPadding: 0.2,
                cursor: 'pointer',
                dataLabels: {
                    enabled: true,
                    color: '#000000',
                    connectorColor: 'transparent',
                    formatter: function() {
                        return '<b>'+ this.y;
                    }
                }
            }
        },
        series: [{
            type:'line',
            name: 'Total',
            data: valuesArray
        }]
    });
});
</script>
<div id="CHANGEME">
</div>

Answer 1

Here: valuesArray.push([parseFloat(week), total]); you are parsing only x-value, do the same with y-value: valuesArray.push([parseFloat(week), parseFloat(total)]);
