Highcharts 24 hours displayed on x axis

Highcharts 24 hours displayed on x axis - javascript

I would like to show 24 hour days going across the Highcharts chart with 1 hour intervals on the x axis and 7 days on the y axis.
How do I get the chart to start at midnight and run for 24 hours across?
As you can see below the chart is currently starting at 8:00am and going until 3:00pm. Instead we would like it to start at 12:00am and end at 11:59pm.

----------------EDIT----------------
I updated the data to replicate what we actually want. The output is working but "broken". We would like the graph to look like the picture.

You can use yAxis.min and yAxis.max for setting the min and max values of your axis. You can use tickPositioner for setting the positions of your labels on axis:
http://api.highcharts.com/highcharts/yAxis.tickPositioner
yAxis: {
min: Date.UTC(2010, 0, 1, 0, 0, 0),
max: Date.UTC(2010, 0, 2, 0, 0, 0),
type: 'datetime',
tickPositioner: function() {
var info = this.tickPositions.info;
var positions = [];
for (i = Date.UTC(2010, 0, 1, 0, 0, 0); i <= Date.UTC(2010, 0, 2, 0, 0, 0); i += 3600 * 1000) {
positions.push(i);
}
positions.info = info;
return positions;
},
lineWidth: 1,
dateTimeLabelFormats: {
day: '%H:%M'
},
title: {
enabled: false
}
},
Here you can see an example how it can work:

Chart.js Dynamically Updating Chart with X Axis Time

I'm using Chart.js version 2.7.1 and I am dynamically updating my Line chart when temperature data comes in.
The problem is that the lines never pass the halfway mark of the x axis in time. Every time I update, the chart auto scales the right side ( max time ) of the x axis to be further out, so my data never approaches the right side of the chart. What I want is for the line to approach the right side, and only a small margin of time is extended into the future for the x-axis each time I update. How can I accomplish this?
Here is how I configure the chart:
var ctx = document.getElementById('tempChart').getContext('2d');
ctx.canvas.width = 320;
ctx.canvas.height = 240;
var chart = new Chart(ctx, {
type: 'line',
data: {
labels: [],
legend: {
display: true
},
datasets: [{
fill: false,
data: [],
label: 'Hot Temperature',
backgroundColor: "#FF2D00",
borderColor: "#FF2D00",
type: 'line',
pointRadius: 1,
lineTension: 2,
borderWidth: 2
},
{
fill: false,
data: [],
label: 'Cold Temperature',
backgroundColor: "#0027FF",
borderColor: "#0027FF",
type: 'line',
pointRadius: 1,
lineTension: 2,
borderWidth: 2
}]
},
options: {
animation: false,
responsive: true,
scales: {
xAxes: [{
scaleLabel: {
display: true,
labelString: 'Time ( UTC )'
},
type: 'time',
time: {
tooltipFormat: "hh:mm:ss",
displayFormats: {
hour: 'MMM D, hh:mm:ss'
}
},
ticks: {
maxRotation: 90,
minRotation: 90
}
}],
yAxes: [{
scaleLabel: {
display: true,
labelString: 'Temperature ( Celcius )'
},
}]
}
}
});
Here is the chart:

as you can see in the following snippet and thanks also to Daniel W Strimpel for creating the initial snippet, you problem is in the hot and cold temperature data.
{ x: new Date(2019, 0, 1, 14, 1, 19, 0), y: Math.random() * 0.5 + 35 },
{ x: new Date(2019, 0, 1, 14, 1, 20, 0), y: Math.random() * 0.5 + 35 },
{ x: new Date(2019, 0, 1, 14, 1, 21, 0), y: Math.random() * 0.5 + 35 },
{ x: new Date(2019, 0, 1, 14, 1, 22, 0), y: Math.random() * 0.5 + 35 },
{ x: new Date(2019, 0, 1, 14, 1, 23, 0), y: Math.random() * 0.5 + 35 },
{ x: new Date(2019, 0, 1, 14, 1, 24, 0), y: Math.random() * 0.5 + 35 },
{ x: new Date(2019, 0, 1, 14, 1, 25, 0), y: Math.random() * 0.5 + 35 },
{ x: new Date(2019, 0, 1, 14, 1, 26, 0) },
{ x: new Date(2019, 0, 1, 14, 1, 27, 0) },
{ x: new Date(2019, 0, 1, 14, 1, 28, 0) },
{ x: new Date(2019, 0, 1, 14, 1, 29, 0) },
{ x: new Date(2019, 0, 1, 14, 1, 30, 0) }
both of those arrays have n number of entries in the end missing the y coordinate including the temperature value. I recreated your scenario by deleting the y for the 5 last entries of the cold and hot temperatures data.
The chart will add the date to the x axis, but it will not add a temperature value and the line will not show up.
{x: new Data(2019, 0, 14, 1, 26, 0) }
The code snippet recreates your scenario, you can run it to understand the problem and fix it by adding the y value to the last 5 entries in the getHotTempData and getColdTempData
var ctx = document.getElementById('tempChart').getContext('2d');
ctx.canvas.width = 320;
ctx.canvas.height = 240;

How to keep side bars in Chartjs bar graph from clipping?

I created a chartjs bar graph to represent a set of measurements over a 60 minute interval. I have managed to get the graph up and running but the end bars of it keep getting clipped. The code is here https://jsfiddle.net/bagelboy/yxs9tr5c/
//
var hourBarctx = document.getElementById("hourBarChart");
var hourBarChart = new Chart(hourBarctx, {
// type: 'line',

// max: moment.unix(new Date(2018, 1, 0, 0, 30, 0).getTime() / 1000),
moment.unix(new Date(2018, 1, 0, 0, 0, 0).getTime() / 1000),
moment.unix(new Date(2018, 1, 0, 0, 1, 0).getTime() / 1000),
moment.unix(new Date(2018, 1, 0, 0, 2, 0).getTime() / 1000),
moment.unix(new Date(2018, 1, 0, 0, 3, 0).getTime() / 1000),

Anyone know how to keep the ends from being clipped like this?

I think it's the way you are trying to do the axis, its looking to show the values between 00-01, 01-02 etc, in the last data point your axis doesn't go to 1am, and the first data point is similar, i was able to fix it by changing:
min: moment.unix(new Date(2018, 1, 0, 0, 0, 0).getTime() / 1000),
max: moment.unix(new Date(2018, 1, 0, 0, 60, 0).getTime() / 1000),
to:
min: moment.unix(new Date(2018, 1, 0, 0, -1, 0).getTime() / 1000),
max: moment.unix(new Date(2018, 1, 0, 0, 61, 0).getTime() / 1000),
Might not be exactly what you want but in the fiddle (after adding moment.js as a dependency) it doesn't cut off your bars.
I haven't worked with time like this, but maybe the data supplied needs to be different to get it to work.

how to pass values to tooltip which not in x and y axis in highcharts

my result is like
my expected tooltip
I need values in tooltip I don't know why it results in undefined value but in console.log has a value of android also, but when I do console.log(this.series.android) am getting undefined for android values.
Am new to high charts any help would be appreciated
Thanks in advance

Here modified_data is the data object containing additional data need for displaying exta information in tooltip
var newseries;
$.each(jsond, function(i, item) {
var modified_data = [];
$.each(item.data, function(j) {
modified_data.push({
y: item.data[j],
android: item.android[j]
})
})
newseries = {};
newseries.name = item.name;
newseries.data = modified_data;
//newseries.android = item.android;
options.series.push(newseries);
});
Tooltip formatter
formatter: function() {
var s = '<b>' + Highcharts.dateFormat('%H:%M',
new Date(this.x)) + '</b>';
$.each(this.points, function() {
//console.log(this)
s += '<br/>' + this.series.name + ': ' +
this.y + 'm' + '<br/>' + 'Android' + ': ' +
this.point.android + 'm';
});
return s;
},

It is the problem with your data.json file. Check the highcharts documentation. Change your value in the formats mentioned in documentation. For eg:
[
{
"name":"Today",
"data":[[17,0],[5,0], [27,13], [0,0], [28,14], [0,0], [27,8], [0,0], [25,12], [0,0], [27,20], [28,0], [26,22], [0,0], [0,17], [0,19], [60,0], [0,0], [46,0], [0,0], [0,0], [0,0], [0,20], [0,21]]
}
]
and change the tooltip formatter function according to this.

How I can stick together the lines on the Highcharts timeline chart?

I creates the timeline Highchart like this jsfiddle.net
$(function () {
$('#container').highcharts({
chart: {
type: 'columnrange',
inverted: true
},
title: {
text: 'Equipment Status'
},
scrollbar: {
enabled: true
},
xAxis: {
categories: ['Status']
},
yAxis: {
type: 'datetime',
title: {
text: 'Timespan'
}
},
plotOptions: {
columnrange: {
grouping: false
}
},
legend: {
enabled: true
},
tooltip: {
formatter: function () {
return '<b>' + this.x + ' - ' + this.series.name + '</b><br/>' + Highcharts.dateFormat('%e %B %H:%M', this.point.low) +
' - ' + Highcharts.dateFormat('%B %e %H:%M', this.point.high) + '<br/>';
}
},
series: [{
name: 'Producing',
data: [{
x: 0,
low: Date.UTC(2013, 07, 03, 0, 0, 0),
high: Date.UTC(2013, 07, 03, 4, 0, 0)
}, {
x: 0,
low: Date.UTC(2013, 07, 03, 10, 0, 0),
high: Date.UTC(2013, 07, 03, 12, 0, 0)
}, {
x: 0,
low: Date.UTC(2013, 07, 03, 14, 0, 0),
high: Date.UTC(2013, 07, 03, 15, 0, 0)
}
]
}, {
name: 'Breakdown',
data: [{
x: 0,
low: Date.UTC(2013, 07, 03, 4, 0, 0),
high: Date.UTC(2013, 07, 03, 10, 0, 0)
}, {
x: 0,
low: Date.UTC(2013, 07, 03, 18, 0, 0),
high: Date.UTC(2013, 07, 03, 24, 0, 0)
}]
}, {
name: "Changeover",
data: [{
x: 0,
low: Date.UTC(2013, 07, 04, 1, 0, 0),
high: Date.UTC(2013, 07, 04, 5, 0, 0)
}, {
x: 0,
low: Date.UTC(2013, 07, 02, 10, 0, 0),
high: Date.UTC(2013, 07, 02, 23, 0, 0)
}, ]
}, {
name: "TrialRun",
data: [{
x: 0,
low: Date.UTC(2013, 07, 04, 5, 0, 0),
high: Date.UTC(2013, 07, 04, 13, 0, 0)
}, {
x: 0,
low: Date.UTC(2013, 07, 02, 2, 0, 0),
high: Date.UTC(2013, 07, 02, 10, 0, 0)
}]
}]
});
});
As you can see, first part (with date range 2 August 02:00 - August 2 10:00 and has orange color) was placed directly before the second part (with date range 2 August 10:00 - August 2 23:00 and has green color). But between them we see a wite space. How I can remove this white space from chart, where dates are stuck together (like this: end of first part August 2 10:00, start of second part 2 August 10:00)

You don't need to do anything in CSS - that's overkill, and causes maintenance headaches.
Highcharts has options for this, and many other formatting issues.
In your case, just set the borderWidth to 0 in your plotOptions:
plotOptions: {
columnrange: {
borderWidth:0,
}
}
(and/or set borderColor: 'transparent')
Example:

JSFiddle Link
I would like to highlight the tick's current timestamp (hour/minutes) by, for example, a single vertical line in red at the current time.
Is it possible?
Thank you !

Hello there Peter Krzywokulski,
By creating a new variable for the today's time:
var today = new Date();
And as the guys mentioned here, creating a plotline:
plotLines: [{
value: today,
color: 'red',
width: 2
}]
You can check it out here: JSFfiddle
Good luck!

As Pawel Fus said, I just need to use plotLines options.
yAxis: {
type: 'datetime',
title: {
text: 'Timespan'
},
plotLines: [{
value: Date.UTC(2013, 07, 02, 23, 30, 0),
color: 'red',
width: 2
}]
}
