Highcharts Date.UTC does not work properly for real data

I've built something like this. I get my data from the server, put it in an object called series, and pass it to 'series' in Highcharts code block. Basically, for every staff, there will be a date, and my default value(Y-Axis) is '1' for now. However, I can't get dates on the chart as expected even if it looks that I had correct data and did correct parsing. Unexpectedly, I get my millisecond values as Y-axis values, which does not make any sense, and every staff has a default date, which is 1 January. (For ex., staff 1, 1 January, x-axis value = 1554422400000)
I get dates like this, 19-02-2019 17:32. Then I split them, and use it like this,
([Date.UTC(parseInt(yearsplit[0]), datesplit[1]-1, parseInt(datesplit[0])), 1])
which looks exactly the same format in Highcharts, ([Date.UTC(1971, 2, 16), 0.86])
var responsePromise = $http.post('statistics/getAllProtocolRecords', data, null);
responsePromise.success(function (dataFromServer, status, headers, config) {
var series = [{
name: "",
data: []
}];
dataFromServer.protocolRecords.forEach((data) => {
var datesplit = data.checkupDate.split("-");
var yearsplit = datesplit[2].split(" ");
series.push({
name: data.staff,
data: [Date.UTC(parseInt(yearsplit[0]), datesplit[1]-1, parseInt(datesplit[0])), 1]
})
});
series.shift();
Highcharts.chart('container', {
chart: {
type: 'spline'
},
title: {
text: 'Toplam Muayene Kaydı (' + sysrefHcCheckupType + ')'
},
subtitle: {
text: ''
},
xAxis: {
type: 'datetime',
dateTimeLabelFormats: { // don't display the dummy year
month: '%e. %b',
year: '%b'
},
title: {
text: 'Tarih'
}
},
yAxis: {
title: {
text: 'Toplam Muayene (Gün)'
},
min: 0
},
tooltip: {
headerFormat: '<b>{series.name}</b><br>',
pointFormat: '{point.x:%e. %b}: {point.y:%f} '
},
plotOptions: {
spline: {
marker: {
enabled: true
}
}
},
colors: ['#00bdff', '#FF0700', '#df0300', '#ff0700', '#c0df00'],
series: series
});
});

I've just realized that I'd made a little mistake in push function. In series.push, 'data' should like this, surrounded by array brackets:
data: [
[ Date.UTC(parseInt(yearsplit[0]), parseInt(datesplit[1])-1, parseInt(datesplit[0])), 1]
]

Highchart performance slow on plotting live data

I am plotting live data in Highchart's(4.2.4) Line type chart for each second data i.e. 60 points for 1 min. and requirement is to collect each second data for long duration. I am using below code to add point in series. The number of series I have is 20. And for each series I have to add point per second. The turboThreshold set for each series is also around 2000. And slicing should be done after 1000 points data.
chart.series[0].addPoint(point, false, data > 1000?shift: false, false);
I see a very low performance my browser keeps hanging and also chart is very irresponsive after some time. What can I do for better performance? I have tried below stuff:
1) Off the animation for series :
plotOptions: {
series: {
animation:false,
states: {
hover: {
lineWidthPlus: 0
}
}
}
},
2) Turn off animation and redrawing on addpoint to the chart
3) Turn off markers for series
4) Included boost.js module in application
script src="https://code.highcharts.com/modules/boost.js"

Without your actual code I can only speculate what you're doing, but my assumption is you're trying to redraw the chart every time you add a point, that would be 20 redraws per second, which is pretty excessive and will probably take more than 1 second to complete the redraws which means there will be new points added while old ones are still being drawn. Set the redraw to false on adding points and manually redraw every second or at random.
Example code:
$(function() {
var series = function(i) {
return {
name: 'Random data '+i,
data: (function() {
// generate an array of random data
var data = [],
time = (new Date()).getTime(),
i;
for (i = -19; i <= 0; i += 1) {
data.push({
x: time + i * 1000,
y: Math.random()
});
}
return data;
}())
};
};
$(document).ready(function() {
Highcharts.setOptions({
global: {
useUTC: false
}
});
$('#container').highcharts({
chart: {
type: 'line',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: function() {
var chart = this;
// set up the updating of the chart each second
setInterval(function() {
for (var i = 0; i < 20; i++) {
var series = chart.series[i];
var x = (new Date()).getTime(), // current time
y = Math.random();
series.addPoint([x, y], false, false,false);
}
chart.redraw();
}, 1000);
}
}

});
});

Have an issue with JavaScript, AJAX code displaying data

I need some tips from you out there to come over a good solution on my problem with JavaScript, AJAX and JSON data. I want to fill a generic set with barcharts (I am using HighCharts) on my web page. The data is in JSON format which from the start I only used date and value as pair data set. The solution works fine of I had only one bar chart it, but I have a lot of charts on my page and I need to show all of them (up to twelve).
Now I want to adjust for displaying more than one graph. In the code below the DataMacro array works fine with the chart. It also has a hard coded ID matching a . Now I have a series of in the page like id=barchart11, id=barchar21, and so on. In the dataset I have made a tag called PanelCodeUI that I am going to use looping through the dataset. The problem is how to do that. The each-loop will now fill in all date,value for all vessels.
And further it I need to restructure the function which is displaying the barchart. The best thing would be to call a function with a data array and panelCodeUI id just replacing the name of the barchart and set in the datamacro as is. But I don’t know how to do this. The data is mixed between all vessels and I need to collect all data before sending to a function. So is the problem with AJAX and JavaScript with is asynchron. I need to ensure that it behaves correctly and fast.
Maybe I need to change my dataset, or I need to do this in several step like finding all vessel IDs then do another AJAX call to get date,value pair from a vessel and then displaying. I hope there is a way to do this with this data set and hope somebody can help me on this
Here is a bit of the JSON data set:
[
{"__type":"Demo.Entities.OilProductionLast5DaysEntity","Date":1465084800000,"Value":844,"VesselId":1,"SectorId":2,"PanelCodeUI":"21","VesselCodeUI":"21","VesselSorting":1},
{"__type":"Demo.Entities.OilProductionLast5DaysEntity","Date":1465084800000,"Value":8720,"VesselId":4,"SectorId":1,"PanelCodeUI":"11","VesselCodeUI":"12","VesselSorting":2},
{"__type":"Demo.Entities.OilProductionLast5DaysEntity","Date":1465084800000,"Value":948,"VesselId":5,"SectorId":1,"PanelCodeUI":"11","VesselCodeUI":"11","VesselSorting":1},
{"__type":"Demo.Entities.OilProductionLast5DaysEntity","Date":1465084800000,"Value":0,"VesselId":6,"SectorId":3,"PanelCodeUI":"31","VesselCodeUI":"31","VesselSorting":1},
{"__type":"Demo.Entities.OilProductionLast5DaysEntity","Date":1465171200000,"Value":2067,"VesselId":1,"SectorId":2,"PanelCodeUI":"21","VesselCodeUI":"21","VesselSorting":1}
]
And here is the JavaScript code so far:
$(function () {
var datamacro = [];
$.ajax({
type: "POST",
url: '../Services/HighChartService.asmx/GetOilProductionLast5DaysByActiveVessels',
data: '',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (seriedata) {
console.log(JSON.stringify(seriedata.d));
var productions = seriedata.d;
$.each(productions, function (index, productions) {
var yval = productions.Value;
var xval = productions.Date;
var x = [xval, yval];
datamacro.push(x);
//alert("productions Name: " + productions.Date + "\nID: " + productions.Value);
});
$(function () {
//var bchart = '#barchart' + vesselindex.toString();
// want this to be looped with generic names like #barchart11, #barchart21, #barchart31 and so on
$('#barchart11').highcharts({
chart: {
type: 'column'
},
title: {
text: 'LAST FIVE DAYS'
},
subtitle: {
text: ''
},
xAxis: {
type: "datetime",
tickInterval: 24 * 3600 * 1000,

},
//crosshair: true
},

},
yAxis: {

},
title: {

}
},

return Highcharts.dateFormat('%d/%m/%Y', new Date(this.x)) + '<br/>' + ' in barrels: ' + this.y;
}
},

pointPadding: 0.2,
borderWidth: 0
}, series: {
pointRange: 24 * 3600 * 1000, // one day
pointInterval: 3600 * 1000
}
},
series: [{
//name: '',
showInLegend: false,
data: datamacro,
dataLabels: {
enabled: true,
rotation: -90,
color: '#FFFFFF',
align: 'right',
format: '{point.y:.1f}', // one decimal
y: 10, // 10 pixels down from the top
style: {
fontSize: '13px',
fontFamily: 'Verdana, sans-serif'
}
}
}]
});
});
},
error: function (r) {
alert(r.responseText);
},
failure: function (r) {
alert(r.responseText);
}
});
});

If i understand correctly, you would like to draw a chart for each different panelCodeUI ?
If that's the case, change your code after AJAX success with that :
var productions = seriedata.d;
var listPanelCodeUI = productions.map(function(p){return p.PanelCodeUI}).filter(function(item, pos, self) {
return self.indexOf(item) == pos;
});
//listPanelCodeUI : [21,11,31]
listPanelCodeUI.sort();
listPanelCodeUI.forEach(function(e){
datamacro = [];
//Create a div for each panelCodeUI
$("body").append("<div id='barchart" + e + "'></div>");
var divId = "#barchart"+e;
//Filter productions for specific panelCodeUI
var data = productions.filter(function(p){return p.panelCodeUI === e});
data.forEach(function(d){
var yval = d.Value;
var xval = d.Date;
var x = [xval, yval];
datamacro.push(x);
});
$(function () {
$(divId).highcharts({
...
})
})
}

That's what you need to parse your data:
charts = [];
$.each(productions.map(function(el) {
return el.PanelCodeUI;
}).filter(function(el, index, arr) {
return arr.indexOf(el) === index;
}), function(index,PanelCodeUI) {
var serie = productions.filter(function(el) {
return el.PanelCodeUI === PanelCodeUI;
});
$.each(serie, function(index, production) {
datamacro.push([production.Value, production.Date]);
});
drawChart('#barchart' + PanelCodeUI, 'LAST FIVE DAYS', datamacro);
});
Also i made this helper function to create the charts:
function drawChart(containerID, chartTitle, data) {
charts.push(new Highchart.Chart({
chart: {
type: 'column',
renderTo: containerID
},
title: {
text: chartTitle
},
subtitle: {
text: ''
},
xAxis: {
type: "datetime",
tickInterval: 24 * 3600 * 1000,
labels: {
rotation: -45,
align: 'right'
},
dateTimeLabelFormats: { // don't display the dummy year
day: '%e. %b',
},
//crosshair: true
},
credits: {
enabled: false
},
yAxis: {
labels: {
enabled: false
},
title: {
text: null
}
},
tooltip: {
formatter: function() {
return Highcharts.dateFormat('%d/%m/%Y', new Date(this.x)) + '<br/>' + ' in barrels: ' + this.y;
}
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
},
series: {
pointRange: 24 * 3600 * 1000, // one day
pointInterval: 3600 * 1000
}
},
series: [{
//name: '',
showInLegend: false,
data: data,
dataLabels: {
enabled: true,
rotation: -90,
color: '#FFFFFF',
align: 'right',
format: '{point.y:.1f}', // one decimal
y: 10, // 10 pixels down from the top
style: {
fontSize: '13px',
fontFamily: 'Verdana, sans-serif'
}
}
}]
}));
}

Displaying time based logs in in HighCharts

I need to display time value of some logs which I fetch from a device,on X-axis of a column graph. The column graph has constant values for Y-axis, basically I want the logs to be shown as sticks as the logs are fetched.
The logs have the following date,time format : 2015-05-07T06:08:54.430062Z
I understand this is the ISO format, so I convert "06:08:54.430062" to milliseconds using
var myDate = new Date(dt);
var result = myDate.getTime();
The result obtained is like this 1430978934438. It so happens that when I convert I get similar values for other logs as well, even if they have a different time instant.
So suppose I have 10 logs, the graph only shows 4 of them. I use
var value=10;// this is a fixed constant value, since I want the log sticks to be of same height.
series.addPoint([result , value], false, false);
How can I see all the logs as sticks corresponding to each log entry ?
If you need more information, let me know. I am fairly new to HighCharts and JS, so any help in the right direction would be really helpful.
Thanks
Added code below
for (var i = 0; i < nSeries; i++) {
dt=jsonData[i].isodate;
var myDate = new Date(dt);
var result = myDate.getTime();
var series = mychart.series[0];
series.addPoint([result, value], false, false);
}
mychart.redraw();
instance.create = function(Highcharts, container) {
Highcharts.setOptions({
global: {
useUTC: false
}
});
var self = this;
mychart = new Highcharts.Chart({

};

How do I add secondary axis to highstock charts?

I'm still pretty wet behind the ears when it comes to javascript. I need some help adding a secondary axis that is something like revenue to a highstock chart that also uses $.getJSON (JSONP) to snag a json file to populate the data.
Check out the JSFiddle example here. And here is the sample data set to play with. And finally, an example of secondary axis in Highcharts.
$(function () {
var seriesOptions = [],
seriesCounter = 0,
names = ['MSFT', 'AAPL', 'GOOG'],
// create the chart when all data is loaded
createChart = function () {
$('#container').highcharts('StockChart', {
rangeSelector: {
selected: 4
},
yAxis: {
labels: {
formatter: function () {
return (this.value > 0 ? ' + ' : '') + this.value + '%';
}
},
plotLines: [{
value: 0,
width: 2,
color: 'silver'
}]
},
yAxis: {
floor: 0
},
plotOptions: {
series: {
compare: 'value'
}
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b> ({point.change}%)<br/>',
valueDecimals: 2
},
series: seriesOptions
});
};
$.each(names, function (i, name) {
$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=' + name.toLowerCase() + '-c.json&callback=?', function (data) {
seriesOptions[i] = {
name: name,
data: data
};
// As we're loading the data asynchronously, we don't know what order it will arrive. So
// we keep a counter and create the chart when all the data is loaded.
seriesCounter += 1;
if (seriesCounter === names.length) {
createChart();
}
});
});
});
Any help and explanations (so I can learn) is much appreciated. I'm still trying to learn how to tie jsonp and charting together, especially multiple series of data and json files.

Write it like this:
yAxis: [{
labels: { ... },
title: { ... },
...
},
{
labels: { ... },
title: { ... },
...
}]
