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);
}
}

},

return '<div class="myToolTip" title="Hello">'+this.value+'</div>';
},
}
},

},

});
Output
Expected Output
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);
}
}

Stuck on the final bits of a multi series line chart

I built a multi series Highcharts https://www.highcharts.com/ line chart with irregular time data. It's almost there, but I'm doing something wrong with the data and/or data formatting. Anyone have a hint or two to throw my way?
The date from the database was converted from '02/03/2009' to javascript time in php using
$date = strtotime($data['As of Date'])*1000;
The other value is a dollar amount.
I haven't yet added the filtered data for 3MO, 6MO, 1YR, 5YR, 10YR
Here is the jsfiddle https://jsfiddle.net/madmichael/th41g4yt/

var text = this.renderer.text(

Highcharts: dateTime in milliseconds is not recognized

I have a highcharts graph consisting of 3 different plot lines. Y axis is a number format, X axis is a dateTime. The plots are being displayed properly but the labels on X show '00:00:00' and the tooltip shows the 1-st of January 1970.
Here's my code for initialising the chart:
Co2Chart = new Highcharts.Chart({
chart: {
renderTo: 'co2-graph',
type: 'spline',
animation: Highcharts.svg,
marginRight: 10,
events: {
load: function () {
updateData();
setInterval(updateData, 5000);
}
}
},
title: {
text: ''
},
xAxis: {
type: 'datetime',
tickPixelInterval: 150,
labels: {
formatter: function () {
return Highcharts.dateFormat('%H:%M:%S', this.value);
}
}
},
yAxis: {
title: {
text: 'CO2, ppm'
},
plotLines: [{
value: 0,
width: 1
},{
value: 1,
width: 1
},{
value: 2,
width: 1
}]
},
tooltip: {
formatter: function () {
return '<b>' + this.series.name + '</b><br/>' +
Highcharts.dateFormat('%Y-%m-%d %H:%M:%S', this.x) + '<br/>' +
Highcharts.numberFormat(this.y, 2);
}
},
legend: {
enabled: true
},
plotOptions: {
spline: {
marker: {
enabled: false
}
}
},
exporting: {

},
series: [{
name: 'Master',
data: []
},
{
name: 'Slave 1',
data: []
},
{
name: 'Slave 2',
data: []
}]
});
This one pushes data:
for(var i = 0; i < array.length; i++){
var time = Date.parse(array[i]["dateTime"]);
Co2Chart.series[0].addPoint(array[i]["masterCo2"], time);
Co2Chart.series[1].addPoint(array[i]["slave1Co2"], time);
Co2Chart.series[2].addPoint(array[i]["slave2Co2"], time);
}
DateTime string that is passed to the Date.parse looks like this 2016-03-28 22:47:49. And in milliseconds – 1459198069000
Any ideas why it's not showing?

The problem is how you use addPoint method:
Co2Chart.series[0].addPoint(array[i]["masterCo2"], time);
Should be:
Co2Chart.series[0].addPoint([time, array[i]["masterCo2"]]);
Or:
Co2Chart.series[0].addPoint({
y: array[i]["masterCo2"],
x: time
});

highcharts linechart color for dynamic data

I would to show my line chart into my html page but the filter date is always disabled and i haven't the data in xAxis, i don't know the cause of this kind of the problem ?
Any help please ?

} else {

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.
