I want to draw a Line Graph with irregular Time interval. I want to pass the data to it via my Ajax calls. How do I do it?
My data is of the following format-
result = {u'New Delhi': [[1383741000000L, 54.2], [1383741900000L, 59.34], [1383742800000L, 64.3]], u'Bangalore': [[1383741000000L, 1608.2], [1383741900000L, 1611.3], [1383742800000L, 1612.29]]}
ie
result = {'name1':[[time1(in secs), value1][time1(in secs), value1]], 'name2':[[time1(in secs), value1][time2(in secs), value2]] }
as in like this.
series: [{
name: result.keys(),
data: result.values()
}]
I should get two lines and thier respective values.
How do I pass my values to the data.?
Here is my code
This is how my result looks like .
var result = [{ // this value is to be passed downwards.
'data': [
[1383741000000, 1608.3000000000002],
[1383741900000, 1611.9999999999973],
[1383742800000, 1612.299999999997]
],
'name': 'Bangalore'
}, {
'data': [
[1383741000000, 54.2],
[1383741900000, 54.300000000000004],
[1383742800000, 54.300000000000004]
],
'name': 'New Delhi'
}]
$(function () {
$('#container').highcharts({
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: WorldClimate.com',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: result, // over here. I'm not getting the line.
});
});
how can I do it?
in success callback of the ajax call pass the response to a method that will parse the data for you as per the required format.
now pass that to the highcharts and build the chart
The problem is that you are setting categories ( one category = 1 value ) and then you are using timestamps to display line. Let's consider: 1383741000000 - that would be mean to display 1383741000000th category and display 1383741000000 ticks and names. This is not possible.
Solution: Remove categories and set xAxis.type = "datetime"

I am using Highcharts to display data from an API. I would like to label my yAxis as "Thousands" and have the numbers shown in a single digit. For example my graph right now labels are 2k, 4k, 6k, 8k, 10k I would like to adjust to formatting to only display 2,4,6,8,10
I am currently using formatter:function () { } to return my the 2k,4k,6k... as it previously displayed 2000,4000,6000... I am having issues figuring how to to properly format my numbers in order to display with a single digit.
My expected outcome is for the yAxis labels displayed on the left side to show 2,4,6,8,10
Here is a jsfiddle of my graph.
Also here is my code:
Highcharts.chart('container', {
chart: {
type: 'line'
},
title: {
text: 'Monthly Average Temperature'
},
subtitle: {
text: 'Source: WorldClimate.com'
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
labels: {
formatter: function () {
return this.axis.defaultLabelFormatter.call(this);
}
},
title: {
text: 'Thousands'
}
},
plotOptions: {
line: {
dataLabels: {
enabled: false
},
enableMouseTracking: false
}
},
series: [{
name: 'Tokyo',
data: [3625, 4320, 4055, 4852, 5120, 6251, 7852, 8000, 9102, ]
}, {
name: 'London',
data: [2210, 3152, 3852, 4102, 4300, 4657, 6521, 7022, 7982]
}]
});
You can use the label.formatter callback with the logic shown below to display wanted format.
Demo: https://jsfiddle.net/BlackLabel/c0e2jwa6/
yAxis: {
labels: {
formatter() {
return this.value / 1000
}
},
title: {
text: 'Thousands'
}
},

I am using the columnrange type from Highcharts-more. The default data labels formatter puts the low / high data at both ends of the range, which is nice.
but when I use scrollbar,high labels don`t move Follow scroll,
How do I setting,to use scrollbar in columnrange chart?
example:enter link description here
Highcharts.chart('container', {
chart: {
type: 'columnrange',
inverted: true
},
title: {
text: 'Temperature variation by month'
},
subtitle: {
text: 'Observed in Vik i Sogn, Norway, 2017'
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
max:4,
scrollbar: {
enabled: true
}
},
yAxis: {
title: {
text: 'Temperature ( °C )'
}
},
tooltip: {
valueSuffix: '°C'
},
plotOptions: {
columnrange: {
dataLabels: {
enabled: true,
format: '{y}°C'
}
}
},
legend: {
enabled: false
},
series: [{
name: 'Temperatures',
data: [
[-9.9, 10.3],
[-8.6, 8.5],
[-10.2, 11.8],
[-1.7, 12.2],
[-0.6, 23.1],
[3.7, 25.4],
[6.0, 26.2],
[6.7, 21.4],
[3.5, 19.5],
[-1.3, 16.0],
[-8.7, 9.4],
[-9.0, 8.6]
]
}]
});
This is Highcharts bug, which is already fixed in the master branch and will be published in version 7.0.2. In the meantime you can use the code from master branch:
<script src="https://github.highcharts.com/master/highstock.src.js"></script>
<script src="https://github.highcharts.com/master/highcharts-more.js"></script>
or the older Highcharts version:
<script src="https://code.highcharts.com/stock/6/highstock.js"></script>

I am trying to achieve this:
Basically I click on a button and a loading spinner will display and once the highchart is ready it will display. So how can i go about achieving this dynamic highcharts functionality ?
Load the Data from your database using ajax and call the charts function.
$("#btn").click(function(){ //function called on button click.
$.ajax({
url: "dataURL",
success: function(result){
//result should be a array of json and the format of data should be similar to what Highcharts uses.
drawChart(result); //calling highcharts function to draw chart.
}
});
});
function drawChart(data)
{
$('#container').highcharts({ //html body should have div with id container.
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: WorldClimate.com',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: data //this is where you pass the data to create the chart.
});
}
}
I have made a fiddle example to show this, but since i cannot load data dynamically i have created a local variable json and it is creating the chart on click of a button.

I'm trying to make a Razor loop in Javascript. I've tried this code, but this wouldn't work. Nothing is displayed into the web-page.
Code:
$(function () {
$('#container').highcharts({
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: WorldClimate.com',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: [
#{int i=0, compte = Model.statistique.Count;}
#foreach (var item in Model.statistique) {
<text>
{
name: '#(item.nomProcessus)',
data: [#(item.lundi), #(item.mardi), #(item.mercredi), #(item.jeudi), #(item.vendredi)]
}
</text>
if (i < compte) {
#:,
}
else
{
#:]
}
i++;
}
});
});
Original code:
jsFiddle
How do I to make the foreach razor loop works into it, please?
Any brilliant idea?
Try this
series: [
#foreach(var item in Model)
{
#:{ name: '#item.nomProcessus', data: [#(item.lundi), #(item.mardi), #(item.mercredi), #(item.jeudi), #(item.vendredi)] },
}
]
Note: You don't need to worry about that last coma. It is acceptable.
I am trying to use high chart. I am new to high chart also new to jquery also. I was trying load categories and series into the line chart. This is the code which i am used.
<script type="text/javascript">
$(function () {
function getData(){
alert('fff');
$.ajax({
url:"high_line_data.php",
type:"POST",
success:function(resp){
chart.series[0].setData(resp);
}
});
}
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'line',
marginRight: 130,
marginBottom: 25,
events: {
load: getData
}
},
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: WorldClimate.com',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -10,
y: 100,
borderWidth: 0
},
series: []
});
});
</script>
and php script
I am echoing the series result as
name:'Test',
Data : '1,3,4,5'
How can I resolve this. Please help.
parse the output of the php from text to array. highcharts also accepts a direct array of integers as input to plot the data.
hope this will be useful
You should replace your string values with numbers. Obiously you can use JSON format to add points.
