remove grid line on chart

Question

I have the charts of lib HighCharts and I want to remove the gridline of yAxis on charts I write gridLineWidth: 0 but gridlines are not removing All code:

<script type="text/javascript">
(function($){ // encapsulate jQuery

$(function() {
    Highcharts.setOptions({
        lang: {
            rangeSelectorZoom: 'Маcштаб',
            rangeSelectorFrom: 'От',
            rangeSelectorTo: 'До',
            thousandsSep: ' '
        },
        global: {
            useUTC: false
        }
    });

    $.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=aapl-c.json&callback=?', function(data) {
        // Create the chart
        window.chart = new Highcharts.StockChart({
            chart : {
                borderColor: 'white',
                renderTo : <?php echo "cont".$i; ?>,
                backgroundColor: '#f9f9f9' // Сделаем слегка серый фон
            },

            rangeSelector: {
                buttons: [  
                { 
                    type: 'week', 
                    count: 1, 
                    text: 'Неделя',
                },  
                { 
                    type: 'month', 
                    count: 1, 
                    text: 'Месяц',

                selected: 1 // Какая кнопка выбрана по умолчанию
            },

Answer 1

The problem is not the gridLineWidth. You've set that correctly.

In addition you need to set the minorGridLineWidth that you have to set to 0

Answer 2

If you doesn't want to touch the config object, you just hide the grid by css:

.chart-container .highcharts-grid {
   display: none;
}

Answer 3

you just need to gridLineWidth set to 0
yAxis: {
           min:0,
           categories: ["","Low","Medium","High"],
           tickWidth: 0,
           crosshair: false,
           lineWidth: 0,
           gridLineWidth:0,//Set this to zero
           title: '',
           labels: {
                       formatter: function () {
                           return this.value;labels
                           }            
                       },
                       showEmpty: false
}

Answer 4

None of the mentioned solutions worked for me, so this one finally worked (taken from Sparklines examples: https://www.highcharts.com/demo/sparkline):

yAxis: {
    startOnTick: false,
    endOnTick: false,
    tickPositions: [],
}
