I'm using highchart for statistics with xaxis type categories and i wanna the xaxis separate in range
I want to add this small separator like in the phots

Here's the code that i'm using , for the first photo i use the accessiblity with rangeDescription accessibility: { rangeDescription: 'Range: 2010 to 2017' } But here i want to use xaxis : {type : 'category'}
chart: {
renderTo: 'container'
},
title: {
text: 'Solar Employment Growth by Sector, 2010-2016'
},
subtitle: {
text: 'Source: thesolarfoundation.com'
},
yAxis: {
title: {
text: 'Number of Employees'
}
},
xAxis: {
categories :[2010,2011,2012,2013,2014,2015,2016,2017]
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle'
},
plotOptions: {
series: {
label: {
connectorAllowed: false
},
}
},
series: [{
name: 'Installation',
data: [43934, 52503, 57177, 69658, 97031, 119931, 137133, 154175]
}, {
name: 'Manufacturing',
data: [24916, 24064, 29742, 29851, 32490, 30282, 38121, 40434]
}, {
name: 'Sales & Distribution',
data: [11744, 17722, 16005, 19771, 20185, 24377, 32147, 39387]
}, {
name: 'Project Development',
data: [null, null, 7988, 12169, 15112, 22452, 34400, 34227]
}, {
name: 'Other',
data: [12908, 5948, 8105, 11248, 8989, 11816, 18274, 18111]
}],
responsive: {
rules: [{
condition: {
maxWidth: 500
},
chartOptions: {
legend: {
layout: 'horizontal',
align: 'center',
verticalAlign: 'bottom'
}
}
}]
}
});```
You need to define the tickWidth property and set tickmarkPlacement to on:
xAxis: {
categories: [...],
tickWidth: 1,
tickmarkPlacement: 'on'
}
