HighCharts - Creating a Scatter with datetime

HighCharts - Creating a Scatter with datetime - javascript

I want to create a scater with datetime as the xAxis, I managed to do so but the x-interval is with days, I am having a hard time doing so where the x-interval is with minutes.
My JS:
function startDashboard3DScatter() {
$.getJSON('/Handlers/MainHandler.ashx?op=getNetwork', function (data) {
Highcharts.getOptions().colors = $.map(Highcharts.getOptions().colors, function (color) {
return {
radialGradient: {
cx: 0.4,
cy: 0.3,
r: 0.5
},
stops: [
[0, color],
[1, Highcharts.Color(color).brighten(-0.2).get('rgb')]
]
};
});
// Set up the chart
var chart = new Highcharts.Chart({
chart: {
renderTo: 'networkAlerts',
margin: 100,
type: 'scatter',
width: 600,
height: 300,
options3d: {
enabled: true,
alpha: 10,
beta: 30,
depth: 250,
viewDistance: 5,
frame: {
bottom: { size: 1, color: 'rgba(0,0,0,0.02)' },
back: { size: 1, color: 'rgba(0,0,0,0.04)' },
side: { size: 1, color: 'rgba(0,0,0,0.06)' }
}
}
},
title: {
text: 'Network'
},
plotOptions: {
scatter: {
width: 100,
height: 100,
depth: 20
},
series: {
marker: {
lineWidth: 1
}
}
},
yAxis: {
min: 0,
title: { text: 'Risk Score' }
},
xAxis: {
min: 0,
max: 6,
gridLineWidth: 1,
title: { text: 'Time line' },
labels: {
formatter: function () {
var date = new Date();
date.setDate(date.getDate() - this.value);
return date.toDateFormat();// this.value + ' %';
}
}
},
zAxis: {
min: 0,
max: 10
},
legend: {
enabled: false
},
series: data
});
});
};
My data response from the get request =
data =
[
{"name":"name1", "id":"D/1", "color": "#55BF3B", "data": [[6, 100]]},
{"name":"name2", "id":"D/5", "color": "#55BF3B", "data": [[3, 1]]}
]
The data is ['days before today, yValue']
So i have done this where i send the days before today and i format xAxis, the problem as i said is that the points are with 1day interval and i want to make it 1 minute or 1 hour interval.
Any ideas, I am stuck on this for days.

Ok the solution wasn't very hard after all:
Changed:
labels: {
formatter: function () {
var date = new Date(new Date().getTime() - (this.value * 60 * 60 * 1000));
return date.toDateFormat();
}
}
And in the Server code return the hours instead of days and it works.

// make the container smaller and add a second container for the master chart

// create master and in its callback, create the detail chart
createMaster();
}
);
there is example that i used https://www.highcharts.com/demo/dynamic-master-detail

Adding a new series to a master-detail chart is very simple. You need to only add a new data set and connect it to the right series. For example:
var detailData = [
[],
[]
],
detailStart = data1[0][0];
masterChart.series.forEach((s, index) => {
s.points.forEach(point => {
if (point.x >= detailStart) {
detailData[index].push(point.y);
}
});
});
// create a detail chart referenced by a global variable
detailChart = Highcharts.chart('detail-container', {
chart: {
type: 'area',
...
},
...,
series: [{
data: detailData[0]
}, {
data: detailData[1]
}]
});

trying to output the json value in Highcharts

Using value, value_classification, and timestamp values in json data
I am trying to print as a solid gauge of Highcharts.
The values in series data are inserted as blank values.
What's the problem?
{
"name": "Fear and Greed Index",
"data": [
{
"value": "27",
"value_classification": "Fear",
"timestamp": "21-12-2021",
"time_until_update": "-1639979045"
}
],
"metadata": {
"error": null
}
}
Using that value,
I am trying to complete the solid gauge of Highcharts.
Highcharts Demos › Solid gauge
https://www.highcharts.com/demo/gauge-solid
The code I've tried so far is below.
HTML
<div id="container-speed" class="chart-container"></div>
JAVASCRIPT
$(function () {
var processedData = [];
$.getJSON("https://api.alternative.me/fng/?date_format=en", function (json) {
for (i = 1; i > json.length; i++){
processedData.push(json[i].value);
}
var gaugeOptions = {
chart: {
type: 'solidgauge'
},
title: null,
pane: {
center: ['50%', '85%'],
size: '140%',
startAngle: -90,
endAngle: 90,
background: {
backgroundColor:
Highcharts.defaultOptions.legend.backgroundColor || '#EEE',
innerRadius: '60%',
outerRadius: '100%',
shape: 'arc'
}
},
exporting: {
enabled: false
},
tooltip: {
enabled: false
},
// the value axis
yAxis: {
stops: [
[0.1, '#55BF3B'], // green
[0.5, '#DDDF0D'], // yellow
[0.9, '#DF5353'] // red
],
lineWidth: 0,
tickWidth: 0,
minorTickInterval: null,
tickAmount: 2,
title: {
y: -70
},
labels: {
y: 16
}
},
plotOptions: {
solidgauge: {
dataLabels: {
y: 5,
borderWidth: 0,
useHTML: true
}
}
}
};
// The speed gauge
var chartSpeed = Highcharts.chart('container-speed', Highcharts.merge(gaugeOptions, {
yAxis: {
min: 0,
max: 200,
title: {
text: 'test'
}
},
credits: {
enabled: false
},
series: [{
name: 'test',
data: processedData,
dataLabels: {
format:
'<div style="text-align:center">' +
'<span style="font-size:25px">{y}</span><br/>' +
'<span style="font-size:12px;opacity:0.4">km/h</span>' +
'</div>'
}
}]
}));
});
});

Hint: Check if processedData outputs something.
Mistake: Looping over json data is incorrect as the response is an object and not an array.
Create an IIFE and verify the first part then move ahead with chart creation.
eg.
$(function () {
var processedData = [];
$.getJSON("https://api.alternative.me/fng/?date_format=en", function (json) {
// wrong
for (i = 1; i > json.length; i++){
processedData.push(json[i].value);
}
});
console.log(processedData);
});

I reproduce your code and receive the data using this approach:
fetch("https://api.alternative.me/fng/?date_format=en")
.then(response => response.json())
.then(output => {
const chartData = output.data.map(d => parseFloat(d.value))

Highcharts Column Chart - pointRange causes extra space to the right

I need to display two sets of data on an existing Highcharts column chart in my codebase. The current chart represents a 24 timespan with millisecond units.
For one dataset each value spans an hour while for the other dataset the value spans 6 minutes. I am able to show these values on Highcharts, and even use pointRange to have the data span the proper width of the chart but then there is a gap with no data to the right of the chart. This ruins the formatting in context of the rest of the application.
Is there a way to avoid this extra spacing? If I remove pointRange, the extra spacing is gone on the right but the bars do not fill the area like I want them to.
Here are jsfiddles for each case:

Highcharts: Add point without connecting series

All,
I'm trying to allow for a user to click on a highchart between two data points and draw a line. The resulting line will calculate LARGESTVALUE-SMALLESTVALUE above the rendered line.
I'm attempting to use this example (http://jsfiddle.net/2MdEN/1/).
$(function () {
var chart;
$(document).ready(function() {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'scatter',
margin: [70, 50, 60, 80],
events: {
click: function(e) {
// find the clicked values and the series
var x = e.xAxis[0].value,
y = e.yAxis[0].value,
series = this.series[0];
// Add it
series.addPoint([x, y]);
}
}
},
title: {
text: 'User supplied data'
},
subtitle: {
text: 'Click the plot area to add a point. Click a point to remove it.'
},
xAxis: {
minPadding: 0.2,
maxPadding: 0.2,
maxZoom: 60
},
yAxis: {
title: {
text: 'Value'
},
minPadding: 0.2,
maxPadding: 0.2,
maxZoom: 60,
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
legend: {
enabled: false
},
exporting: {
enabled: false
},
plotOptions: {
series: {
lineWidth: 1,
point: {
events: {
'click': function() {
if (this.series.data.length > 1) this.remove();
}
}
}
}
},
series: [{
data: [[20, 20], [80, 80], null, [60, 40], [85, 60]]
}]
});
});
});
The problem is that is connects the last data point in the series to the newly added point. I'd like the points to be detached from the series to allow for lines being drawn above the generated chart.
Is there any way to accomplish this?
Thank you

You can include a second empty series in your chart config, and change which series you are adding a point to:
events: {
click: function(e) {
// find the clicked values and the series
var x = e.xAxis[0].value,
y = e.yAxis[0].value,
series = this.series[1]; <------------
// Add it
series.addPoint([x, y]);
}
}
You can also then move your point click event into the second series, if you don't want users to be able to remove points from the original data:
series: [{
data: [
[20, 20],
[80, 80], null, [60, 40],
[85, 60]
]
}, {
id: 'dummy',
color: 'rgba(204,0,0,0.9)',
point: {
events: {
'click': function() {
this.remove();
}
}
}
}]
Updated example:
http://jsfiddle.net/2MdEN/107/

I used the following
$(function () {
$('#container').highcharts({
chart: {
type: 'scatter',
margin: [70, 50, 60, 80],
events: {
click: function (e) {
var c = this.series[0].chart;
var s = this.series.length;
var x = e.xAxis[0].value;
var y = e.yAxis[0].value;
if(s == 1) {
c.addSeries('newSeries' + new Date());
c.series[1].addPoint([x, y]);
}else{
if(this.series[this.series.length-1].data.length%2 == 1) {
c.series[this.series.length-1].addPoint([x, y]);
}else{
c.addSeries('newSeries' + new Date());
c.series[this.series.length-1].addPoint([x, y]);
}
}
}
}
},
title: {
text: 'User supplied data!!!!'
},
subtitle: {

High chart formatter not working on Highchart API

I am using Highchart library but very disappointed after using the same. Highchart call back function formatter not working for me for any of the chart.
I am using Highchart API, It return image of the chart. but with wrong x-axis value. I want value to be "hello1, hello2, hello3 etc." but it only gives me number 1, 2, 3...
Please help me.
Link Of Js Fiddle : https://jsfiddle.net/stjk38rz/
Code is
var categories = ['Conflict', 'Identity', 'Role', 'Attitude', 'Agility', 'Fairness'],
count = 0;
var options = {
exporting: {
url: 'https://export.highcharts.com/'
},
chart: {
polar: true,
renderTo: 'container',
zoomType: 'x'
},
pane: {
startAngle: 45,
},
title: {
text: 'Highcharts Polar Chart'
},
xAxis: {
tickInterval: 1,
min: 0,
max: 6,
labels: {
enabled: true,
formatter: function () {
if(this.value.toString().substring(0, 6) == 0)
{
return "hello1";
}
if(this.value.toString().substring(0, 6) == 1)
{
return "hello2";
}
if(this.value.toString().substring(0, 6) == 2)
{
return "hello3";
}
if(this.value.toString().substring(0, 6) == 3)
{
return "hello4";
}
if(this.value.toString().substring(0, 6) == 4)
{
return "hello5";
}
if(this.value.toString().substring(0, 6) == 5)
{
return "hello6";
}
}
}
},
tooltip: {
formatter: function () {
return '<b>' + categories[Highcharts.numberFormat(this.x, 0) - 1] + '</b><br/>' + 'value: ' + this.y;
}
},
yAxis: {
labels: {
enabled: false
},
min: 0,
tickInterval: 10,
tickPositions: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
minorTickInterval: 0
},
plotOptions: {
series: {
pointStart: 0.5,
pointInterval: 1
},
column: {
pointPadding: 0,
groupPadding: 0
}
},
series: [{
type: 'column',
name: 'test data',
data: [{
y: 9.5,
color: '#0FCCD9'
}, {
y: 1,
color: '#ED1334'
}, {
y: 3,
color: '#EDCC13'
}, {
y: 4,
color: '#34ED13'
}, {
y: 5,
color: '#34ED13'
}, {
y: 6,
color: '#34ED13'
}]
}]
};
var obj = {},
exportUrl = options.exporting.url;
obj.options = JSON.stringify(options);
obj.type = 'image/png';
obj.async = true;
$.ajax({
type: 'post',
url: exportUrl,
data: obj,
success: function (data) {
var imgContainer = $("#imgContainer");
$('<img>').attr('src', exportUrl + data).attr('width', '250px').appendTo(imgContainer);
$('<a>or Download Here</a>').attr('href', exportUrl + data).appendTo(imgContainer);
}
});

It appears that formatter isn't being called at all.
This could be because it's a polar chart or possibly there's some other conflict in your code overriding this?
As long as you only want text, you can pass the text in as categories, ie:
var categories = ['Conflict', 'Identity', 'Role', 'Attitude', 'Agility', 'Fairness']
xAxis: {
categories: categories
}
Updated fiddle

Develop Reference

JavaScript is the programming language of the Web.

HighCharts - Creating a Scatter with datetime - javascript

Ok the solution wasn't very hard after all: Changed: labels: { formatter: function () { var date = new Date(new Date().getTime() - (this.value * 60 * 60 * 1000)); return date.toDateFormat(); } } And in the Server code return the hours instead of days and it works.
