Using Highcharts with minutes, seconds and milliseconds as Data not working - javascript

I am trying to chart 1000 meters run, data is given via mySQL Database and brings MeterTime and urDate. urDate is on the x-axis and y-axis should hold seconds. But the chart either plots nothing at all, or everything on the zero line.
I understand I need to change how the charts interprets the time, but only the minutes, seconds and milliseconds are provided. Not sure how I can convert it.
Any anyone see on the jsfiddle and check what i might be doing wrong please?
jsfiddle
var chart;
var data = [{"urDate":"2015-03-04","urTime":"00:02:05","MeterTime":"00:15:534250"},{"urDate":"2015-03-06","urTime":"00:02:25","MeterTime":"00:18:019730"}];
var options = {
chart: {
backgroundColor: '#34495e',
plotBackgroundColor: '#2b3c50',
renderTo: 'container',
type: 'line'
},
title: {
text: '',
x: -20 //center
},
subtitle: {
text: '',
x: -20
},
xAxis: {
categories: []
},
yAxis: {
title: {
name: 'Time'
},
type: 'datetime',
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
series: []
};
var dataXAxis = [],
dataSeries = [{
data: []
}];
data.forEach(function (va) {
dataXAxis.push(formatDate(va.urDate));
dataSeries[0].data.push(formatDate(va.MeterTime));
});
// And assign the correct format to highcharts
options.xAxis.categories = dataXAxis;
options.series = dataSeries;
// create the first chart
chart = new Highcharts.Chart(options);
function formatDate(d) {
d = new Date(d);
var month = d.getMonth();
var day = d.getDate();
month = month + 1;
month = month + "";
if (month.length == 1)
{
month = "0" + month;
}
day = day + "";
if (day.length == 1)
{
day = "0" + day;
}
return (day + '-' + month + '-' + d.getFullYear());
}
UPDATE
I have changed the jsfiddle to include how the data is now loaded from the mySQL query. Thanks to One, below, who gave me the idea to change how the data came in, rather than changing it once it arrived.
New Code looks like this:
var options = {
chart: {
backgroundColor: '#34495e',
plotBackgroundColor: '#2b3c50',
renderTo: 'container',
type: 'line'
},
title: {
text: '',
x: -20 //center
},
subtitle: {
text: '',
x: -20
},
xAxis: {
categories: []
},
yAxis: {
title: {
name: 'Seconds'
},
//type: 'datatime', //y-axis will be in milliseconds
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
series: []
};
var dataXAxis = [], dataSeries = [{data: []}];
data.forEach(function (va) {
dataXAxis.push(formatDate(va.urDate));
console.log('t ' + va.MeterTime);
dataSeries[0].data.push(parseInt(va.MeterTime));
})
// And assign the correct format to highcharts
options.xAxis.categories = dataXAxis;
options.series = dataSeries;
options.yAxis.title.text = 'Seconds';
// create the first chart
chart = new Highcharts.Chart(options);
});
The main difference is how the data comes in:
[{"urDate":"2015-03-04","MeterTime":"15.5343"},{"urDate":"2015-03-06","MeterTime":"18.0197"}]
This comes from a mySQL Query that looks like this:
$isql = "SELECT urDate, time_to_sec(urTime) / (urMiles / 0.00062137) * 1000 AS MeterTime FROM results WHERE uid = " . $_POST['uid'] . " ORDER BY urDate ASC;";
$ires = $mysqli->query($isql);
while ($irow = $ires->fetch_array(MYSQLI_ASSOC)) {
$data_result['userChart'][] = $irow;
}
echo json_encode($data_result);
And the end result, apart from some better styling, is this:
Hope this helps others in the future.

Plotted millisecond as Y axis.
http://jsfiddle.net/kjjn6tn3/3/
secondd = _.map(data , function (v) {return _.reduce(_.map(_.zip(_.map(v['urTime'].split(":"), function(v) {return parseInt(v);}), [60*60,60,1]), function (value , key) {return value[0]*value[1];}), function (x ,y ){ return x+y;})});
dataY = {
name :"pump",
data : secondd
}
same you can do with meter time and plot as Y axis.

QUESTION:
I have created a line chart using C3.js that is updating its values every 2 seconds.
To achieve this goal i use the following code.
UPDATE:
I have noticed that this is happening when i'm swapping from a tab to another of the bowser.Let's say chart is on TAB1 and i swap to TAB2 for 5 minutes, when i get back to TAB1 i have lost some label as you can see in screenshots below and time on the X-axis is 5 minutes later too...
UPDATE2
The problem is related to setInterval almost for sure.
function drawChart1()
{
var chart = c3.generate({
bindto: '#chart11',
//Size of the chart
size: {
height: 250,
width: 952
},
data: {
x: 'x',
columns: []
},
//Color of the lines
color: {
pattern: [ '#ff9896', '#9edae5']
},
axis: {
x: {
//show: false,
label: 'Time',
type: 'timeseries',
tick: {
format: '%H:%M:%S',
//format: '%H:%M',
}
},
y: {
//http://c3js.org/samples/axes_label_position.html
label: 'Kbps'
},
},
legend: {
//position: 'right'
}
});
var chartObj = {
"chart": chart,
"redrawArgs": {},
"truncThreshold": undefined
}
var date = Date.now();
var timeInc = 2000;
//Update values every x seconds
var interval = setInterval(function () {
var dataCols = [];
date = date + timeInc;
var minX = date - 10000;
var maxX = date;
var redrawArgs = chartObj.redrawArgs;
if (!chartObj.truncThreshold) {
chartObj.truncThreshold = maxX;
} else if (minX > chartObj.truncThreshold) {
redrawArgs.length = 1;
} else {
redrawArgs.length = 0;
}
chartObj.chart.axis.range({max: {x: maxX}, min: {x: minX}});
redrawArgs.duration = 0;
var TraficDown1 = 1 + Math.floor(Math.random() * 1000);
var TraficUp1 = 1 + Math.floor(Math.random() * 1000);
dataCols.push(['x', date]);
dataCols.push(['Kbps UP', TraficUp1]);
dataCols.push(['Kbps DOWN', TraficDown1])
redrawArgs.columns = dataCols;
chartObj.chart.flow(redrawArgs);
}, 2000);
}
For some time the code is working as intended:
Problem is that after some minutes I got this strange behaviour, where values are missing on x axis.
Someone can give me some hints? I'm using c3.js and D3.js v3.

found it on here https://c3js.org/reference.html#axis-x-tick-culling
axis: {
x: {
culling: false, // <-- THIS!
//show: false,
label: 'Time',
type: 'timeseries',
tick: {
format: '%H:%M:%S',
//format: '%H:%M',
}
},

I'm using highcharts and am I trying to develop a chart, which can handle live data.
Here is my first try:
var data = [],
chart_interval = undefined;
Highcharts.setOptions({
global: {
useUTC: false
}
});
function addRandomData(dataSet, frequency, yMax, count) {
for (var i = 1; i <= count; i++) {
var x = new Date((new Date()).getTime() + i * frequency),
y = Math.random() * yMax;
dataSet.push({
x: x,
y: y
});
}
return dataSet;
}
function addDataInterval(dataSet, frequency, yMax) {
return setInterval(function() {
var x = new Date(dataSet[dataSet.length - 1].x.getTime() + frequency),
y = Math.random() * yMax;
dataSet.push({
x: x,
y: y
});
}, frequency);
}
// Parameters: dataSet, frequency, yMax, count
addRandomData(data, 1000, 10000, 60);
// Parameters: dataSet, frequency, yMax
addDataInterval(data, 500, 10000);
// Create the chart
Highcharts.stockChart('container', {
chart: {
zoomType: 'x',
events: {
load: function() {
// set up the updating of the chart each second
var series = this.series[0];
setInterval(function() {
series.update({
data: data
}, true);
}, 1000);
}
}
},
rangeSelector: {
buttons: [{
count: 1,
type: 'minute',
text: '1M'
}, {
count: 5,
type: 'minute',
text: '5M'
}, {
type: 'all',
text: 'All'
}],
inputEnabled: false,
selected: 0
},
title: {
text: 'Live random data'
},
exporting: {
enabled: false
},
series: [{
name: 'Random data',
data: data
}]
});
<script src="https://code.highcharts.com/stock/highstock.js"></script>
<script src="https://code.highcharts.com/stock/modules/exporting.js"></script>
<div id="container" style="height: 400px; min-width: 310px"></div>
Problem: If already existing data has different time intervals, such as the newly generated data, the freely selectable zoom don't work.
Have I somewhere make mistake or is this a bug of highcharts?

Highcharts wants time values as timestamps in milliseconds instead of Date objects:
What format does the highcharts js library accept for dates?
Highcharts X-Axis time from JS date
Change how you generate your x values, and the zooming magically starts working again:
var x = (new Date()).getTime() + i * frequency,
...
var x = dataSet[dataSet.length - 1].x + frequency,

I have theorized that in a worst case scenario, Euro/Dollar will never go past 4 usd for 1 euro, so in the Y-axis, i am thinking of having value 0 to 4 and x- axis will have the current time.
In my example above, i cant display 0 to 4 in the y axis. Also i would love the area under the curve to have some color like blue.
How can i make the y -axis show 0 to 4 and
How can i have area under the curve to have a color like blue?
Thanks.

For the y-axis to show values between 0 & 4 use max: your value and for the curve to have a color like blue just change the chart type to area chart:{type:area, .... Here is your example: https://jsfiddle.net/68oe1oLf/

The goal is to create a Highchart line with starting point from X-Value 26th January and with the end point on the X-Value 7th February. Corresponding Y-Values are "260" and "0".
How to create a simple line with these to points in HighCharts? Maybe Highcharts is able to do a linear regression on the fly?!
I have found this demo but I do not know how to pass correctly X-Values in the Date format.

Highcharts doesn't calculate any type of regression or trend lines. In example you have posted, data is calculated before, and Highcharts just displays that. However there is known plugin for trendline: https://github.com/virtualstaticvoid/highcharts_trendline

Trying to get some help with this weird behavior.
I managed to get the highcharts chart, multiple series etc. all setup. When using static values from a inline array, the values are assigned correctly to the chart, but if I pull the numbers out of a csv file, they are not assigned unless I pause execution with an alert message. Please see code below
$(function () {
// every row on report needs
// category defined (left side)
var mycategories = [];
// every column on report needs
// seriesname defined
var headers = [];
var myseriesnames = [];
var lines = [];
var line_tokens = [];
// Read data from csv file
$.get('top10raj.csv', function(data) {
// Split the lines
lines = data.split('\n');
console.log("First line : "+ lines[0]);
headers = lines[0].split(',');
for (var i = 1; i < headers.length; i++) {
myseriesnames.push(headers[i]);
}
//
// display all lines
//
for (var i = 1; i < lines.length; i++) {
line_tokens = lines[i].split(',');
console.log('Equip.No:' + line_tokens[0].trim()); // Equipment Number
console.log(line_tokens[1].trim()); // ActualCost
console.log(line_tokens[2].trim()); // ActualMaterial
console.log(line_tokens[3].trim()); // ActualLabor
console.log(line_tokens[4].trim()); // ActualOther
mycategories.push(line_tokens[0].trim());
}
});

The csv file I am using is shown at the bottom of the source.
if the following line
alert('report ready');
is commented out, I lose all the categories labels and they are replaced by 0..1,2,3.. etc. along the X-Axis. Trying hard to understand why this is happening, but so far no luck in fixing. Appreciate any help I can get with this, as I really want to use the Highcharts library with dynamic data and using only static data from predefined arrays is very limiting.

The problem is that your request for the csv file ($.get ) is executed asynchronously, meaning that the rest of your code is running before the data is returned. Try moving your code into the callback function, something like
//..your code
mycategories.push(line_tokens[0].trim());
}
//moved your code here
