remove grid line on chart - highcharts

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',

text: 'Месяц',
},
{
type: 'year',
count: 1,
text: 'Год'

// specify an interval for ticks or use max and min to get the interval
var interval = Math.round((max-min)/5);
// push the min value at beginning of array
var dataMin=this.dataMin;
var dataMax=this.dataMax;
var positions = [dataMin];
var defaultPositions = this.getLinearTickPositions(interval, dataMin, max);
//push all other values that fall between min and max
for (var i = 0; i < defaultPositions.length; i++) {
if (defaultPositions[i] > dataMin && defaultPositions[i] < dataMax) {
positions.push(defaultPositions[i]);

}

positions.push(dataMax);
return positions;

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
Working demo

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: [],
}

Answer 5

for all other lines here is what worked for me, in some cases using line transparency as the color was the only solution I could find.
$(function() {
$('#container').highcharts({
colors: ['#00f900', '#ffff3c', '#ff2600'],
credits: {
enabled: false
},
exporting: {
enabled: false
},
legend: {
itemDistance: 60
},
lineColor: 'red',
chart: {
type: 'column',
backgroundColor: 'transparent'
},
title: {
text: ''
},
legend: {
itemStyle: {
color: 'white',
fontWeight: 'normal',
fontFamily: 'helvetica',
fontSize: '12px'
}
}
