Highchart add a text under single bar in bar chart

I want to add a percentage value under the single bar. Here is the Fiddle which displays the percentage under all bars. Below is the code as well. I want to compare the last two values and then add their percentage under the last bar
Code
var colors = ['#a3cb38','#ea2027','#0652dd','#ffc312'];
var dataSum = data.reduce((a,x)=>a+x.y,0);
Highcharts.chart('highchart', {
chart: {
type: 'bar',
backgroundColor: null,
height: 270,
events: {
load: function() {
this.addSeries({
data: [{x: 0, y: 1},{x: 1, y: 1},{x: 2, y: 1},{x: 3, y: 1}],
enableMouseTracking: false,
dataLabels: {
useHTML: true,
formatter:function() {
var pcnt = (data[this.x].y / dataSum) * 100;
return '<span class="" style="color:' + this.point.color + '">' + Highcharts.numberFormat(pcnt) + '%' + '</span> <span class="">' + data[this.x].name + ' this i want put under the bar' + '</span>';
}}
}, true);

How can I add a percentage under only a single bar?
Any help would be highly appreciated

You can use data labels configuration for a single point.
events: {
load: function() {
this.addSeries(..., {
x: 3,
y: 1,
dataLabels: {
useHTML: true,
formatter: function() {
var pcnt = (data[this.x].y / dataSum) * 100;
return '...';
}
}
}]
}, true);
}
}

if (tabOut[da]) {
tabOut[da] = tabOut[da] + 1;
} else {

HighCharts column chart populated with series data from a function

I'm trying to populate a HighCharts dataset with results from SQL Server in Classic ASP. (In the examples obviously there are numbers and names instead of vbscript variables)
The first example is without a function - and works. http://jsfiddle.net/zbpamrhs/
$(function () {
var OnOff = 3
var DivName = []
var DivN = []
var DivTotal = []
var DivColor = []
DivName[0] = 'Div'
DivName[1] = 'Unit A'
DivName[2] = 'Unit B'
DivName[3] = 'Unit C'
DivN[0] = 22
DivN[1] = 10
DivN[2] = 7
DivN[3] = 3
DivTotal[0] = 5.6
DivTotal[1] = 5.8
DivTotal[2] = 5.4
DivTotal[3] = 5.7
DivColor[0] = '#333333'
DivColor[1] = '#c9e7ff'
DivColor[2] = '#4898a4'
DivColor[3] = '#ffd949'
$('#DivCompTotalC').highcharts({
chart: {
type: 'column'
},

});

var chart = $('#DivCompTotalC').highcharts();
//alert(JSON.stringify(chart));
$.each(newSeries, function (i, ns) {
chart.addSeries(ns);
});
});

There are multiple issues :
You are trying to addSeries instead of points as compared to the first working fiddle. chart.addSeries(ns);
seria['data'] = DivTotal[i]; data is supposed to be an array as per the working fiddle.

Disabling label without bar Highstock

I have a column chart Highstock:
http://jsfiddle.net/txfnsubb/
When we change range to smaller values, sometimes it shows us a label of value w/o the bar. For example I see 30 bars and at the end label with 31. Is there a possibility to turn it off? To set chart to showing label only with bar.
$('#container').highcharts('StockChart', {

Plot always starts at 0, highstock spline chart

I have data like this
var data = [];
for(var i=1;i<201;i++){
data.push([i,(Math.random() * (80 - 40 + 1)) + 40])
}
And I'm creating chart like this:
$('.reactivityCont').highcharts('StockChart', {
chart: {
marginTop: 140
},
credits: {
enabled: false
},
rangeSelector : {
selected : 1
},
scrollbar: {
enabled: false
},
navigator: {
top : 40,
xAxis: {
labels: {
formatter: function() {
return this.value;
}
}
}
},
xAxis: {
labels: {
y: 50,
formatter: function() {
return this.value;
}
},
events: {
setExtremes: function (e) {
start = parseInt(e.min);
koniec = parseInt(e.max);
$('.nt').hide();
for(var i = start-1;i<koniec;i++){
$('.nt').eq(i).show();
}
main();
}
}
},
series : [{
type: 'column',
name : 'reactivity',
data : data,
showInLegend: false,
tooltip: {
valueDecimals: 2
}
},
{type: 'spline',
name: 'experiment 1',
data: data2,
color: 'green',
visible: false,
tooltip: {
valueDecimals: 2
}
},
{type: 'spline',
name: 'experiment 2',
data: data3,
color: 'red',
visible: false,
tooltip: {
valueDecimals: 2
}
}
],
legend :{
enabled: true,
margin: 0
},
rangeSelector : {
buttons: [
{
type: 'millisecond',
count: seqLength/5,
text: '0.25'
}, {
type: 'millisecond',
count: seqLength/3,
text: '0.3'
}, {
type: 'millisecond',
count: seqLength/2,
text: '0.5'
}, {
type: 'all',
text: '1.0'
}
],
inputEnabled: false, // it supports only days
selected : 4 // all
}
});
But unfortunately, my plot starts with 0, but it should not, because there is no such a value.
I tried fix it, e. g. by setting plotOptions:pointStart but that didn't work.

This is caused by using column type series, where columns always starts from 0. To prevent this set threshold: null, like this:
series : [{
type: 'column',
threshold: null,
...
}]

You can use theXAxis's min param.
For Example.
xAxis: {
labels: {
formatter: function() {
return this.value;
}
},
min: myInitValue,
max: myEndValue
}
Hope It Helps.
