Tick Interval for 5 days

I need to have my x-axis displayed for every 5 days in Highcharts but for some reason the dates are being displayed properly.

Here is my fiddle.

https://jsfiddle.net/nk3q5ejL/3/

Code:

$(function () {
$('#container').highcharts({
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: WorldClimate.com',
x: -20
},
xAxis: {
categories: ["10/08/2015", "10/09/2015", "10/10/2015", "10/11/2015", "10/12/2015", "10/13/2015", "10/14/2015", "10/15/2015", "10/16/2015", "10/17/2015", "10/18/2015", "10/19/2015"],
tickInterval: 24 * 3600 * 1000 * 5,
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: [{
name: 'Tokyo',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
name: 'New York',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]
}, {
name: 'Berlin',
data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0]
}, {
name: 'London',
data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}]
});
});

Answer

I'm afraid you can use milliseconds in the tickInterval if your chart has datetime axis and this does not seem to be the case (see for example http://api.highcharts.com/highcharts#xAxis.dateTimeLabelFormats), you're just using an array of strings as categories for your x-axis.

If by x-axis displayed for every 5 days, you mean having 10-08-2015, 10-13-2015, 10-18-2015, etc, just use tickInterval: 5 and that will do the trick.

I modified your fiddle with that change: https://jsfiddle.net/nk3q5ejL/4/
