High everyone,
I am trying to get two things to happen. First, I want to create a custom tooltip for a columnrange-type series where the tooltip shows something like HIGH: 'this.point.high' and on a new line "LOW:" 'this.point.low'. Second, I would like these 'low' and 'high' values to populate a form field dynamically. For example, when a user drags the high value for the columnrange entry, I want this to dynamically update a number in the corresponding formfield that collects user input.
Here is a fiddle: https://jsfiddle.net/e9zqmy12/

It seems that your code was almost good except this callback pointFormatter callback - notice that this calls for point already, so this.point refers to undefined, it should be:
tooltip: {
pointFormatter: function() {
console.log(this);
return "LOW: " + this.low + " <br>HIGH:" + this.high;
}
},

I'm using Highcharts' x-range chart module to render a range of multiple values. I have a couple of issues in implementing it.
The hover and select states are not having any effect on the chart
The legend icon is not showing the color of the data
Code below:
var myChart7 = Highcharts.chart('sample', {
chart: {
type: 'xrange',
},
title: null,
xAxis: {
opposite: true,
labels: {
useHTML: true,
formatter: function() {
return this.value + "ms";
},
}
},
yAxis: {
title: {
text: ''
},
labels: {
enabled: true,
},
categories: [],
reversed: true
},
tooltip: {
enabled: false
},
plotOptions: {

},
allowPointSelect: true,

hover: {
color: '#a4edba'
},
select: {
color: '#EFFFEF',
borderColor: 'black',
dashStyle: 'dot'
}
},
pointWidth: 15,
borderRadius: 10,

I don't know if I'm implementing it in the right or wrong way. Please guide me. TIA.
I'm working on Chrome version 85 on mac. Haven't tested it on other browsers.
Those features hasn't been implemented in the version of the Highcharts which you are using. In the current version everything works fine: https://jsfiddle.net/BlackLabel/trxjw4np/
In the x-range series type the legend item doesn't inherit the color from the series, but you can set it programmatically.
Demo: https://jsfiddle.net/BlackLabel/trxjw4np/
events: {
load() {
let chart = this;
chart.legend.allItems.forEach(item => {
item.legendSymbol.css({
fill: item.userOptions.color
})
})
}
}

Well, I have a bar Highchart showing some scores, what I want to get is the x Axis value (the user id) when I click a plot serie.
Making some research I was able to show the x Axis value when I click on the chart background (I am using console.log to show this data), but I a unable to do it clicking any plot serie (the coloured bar)
This is the snippet:
var cats=["1.- John :8","2.- Mark :7","3.- Mary :5","4.- Charles :2","5.- Sarah :1"];
var prcs=[2,12,13,11,15];
Highcharts.chart('container', {
chart: {
type: 'bar',
events:{
click: function(te){
console.log(prcs[Math.round(te.xAxis[0].value)]);
}
}
},
title: {
text: null
},
credits: {
enabled: false
},
xAxis: {
categories: cats,
lineColor: '#FFFFFF',
tickColor: 'transparent',
labels: {
align: 'left',
x: 0,
y: -12,
style: {
textOverflow: 'none',
width:'300px',
whiteSpace:'normal'//set to normal
}
}
},
yAxis: {
min: 0,
title: {
text: null,
},
labels: {
enabled: false
}
},
legend: {
enabled: false
//reversed: true
},
plotOptions: {
series: {
stacking: 'normal',
dataLabels: {
enabled: true,
align: 'left',
color: '#FFFFFF',
x: 0
},
events:{
click: function(te){
console.log(this.name);
}
}
//pointPadding: 0,
//groupPadding: 0
},
bar:{
}
},
series: [{
name: 'High',
color: '#009900',
data: [0,1,0,1,0]
}, {
name: 'Mid',
color: '#FFCC66',
data: [4,3,0,1,1]
}, {
name: 'Low',
color: '#FF6666',
data: [4,4,5,1,0]
}]
});
<script src="https://code.highcharts.com/highcharts.js"></script>
<div id="container" style="height: 210px"></div>
The same in jsFiddle: http://jsfiddle.net/29vfsc4t/5/
If you click on the background you will get the user id, and clicking on any bar you will get the "score", what I need is to get the user id when I click on a bar.
You should be catching the point.event instead of the chart.event to get the point's xAxis category:
plotOptions: {
series: {
stacking: 'normal',
dataLabels: {
enabled: true,
align: 'left',
color: '#FFFFFF',
x: 0
},
point: {
events: {
click: function(te) {
console.log(this.category);
console.log(this.x);
}
}
}
},
bar: {}
},
Note the change to console.log(this.category) to show the xAxis name.
how to draw hh:mm pie chart using highcharts for bellow table
You could try this approach, we get the total amount of time, then create a highcharts chart from the individual points:
const data = [
{
name: 'Line Clear - Line maintenance',
value: '06:29',
color: '#eef441'
},
{
name: 'Incoming Supply Failure (ICF)',
value: '14:44',
color: '#f44242'
},
{
name: '33 KV Line Breakdown',
value: '02:13',
color: '#41f48b'
},
{
name: 'Line Clear - SS maintenance',
value: '00:10',
color: '#4176f4'
},
{
name: 'Momentary Interruptions',
value: '01:11',
color: '#e541f4'
}
];
var totalTimeSeconds = data.reduce((sum,row) => {
return sum + 1.0*moment.duration(row.value).asSeconds();
}, 0.0);
var dataSeries = data.map((row) => {
return {
name: row.name + " (" + row.value +")",
y: moment.duration(row.value).asSeconds() / totalTimeSeconds,
color: row.color
};
});
Highcharts.chart('container', {
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
title: {
text: 'Reason Type'
},
tooltip: {
pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
format: '<b>{point.name}</b>: {point.percentage:.1f} %',
style: {
color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
}
}
}
},
series: [{
name: 'Reason',
colorByPoint: true,

}]
});

I am new to HighCharts and I am trying to display 2 graphs on the same x-axis) axis like shown here: http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/combo-multi-axes/.

The error occurs in "chart1"

You are doing the following:
series:[{
yAxis:1,
},
{
yAxis:2,
}]
You need to do:
series:[{
yAxis:0,
},
{
yAxis:1,
}]
The problem is that axes start indexing at 0. So your index where you set temperature to axis 2 does not work because there is no axis 2. In the demo there are 3 axes, which is why it works with these definitions.
I'm working on a project to register pump curves in a MySQL database. So I'm trying to create the closest possible one chart with 3 yAxis (H, NPSH, Power) and 2 xAxis (flow and efficiency). I uploaded a pump curve image here for better understanding. Note this efficiency is a logarithm scale but I prefer to create a linear scale to make it easy.
Well, every curve chart has more one rotor curve, in this case we have 5 curves which is five types of rotor (176mm, 169mm, 162mm, 154mm and 148mm).
Each rotor gives one data series in a yAxis as H, NPSH, Power and Efficiency.
So I need to create a series for each rotor size whem each series get the values of the data: H,NPSH,Power,Efficiency with its yAxis referals.
Here is the link's page with the code.

tooltip: {
valueSuffix: 'hp'
}
}]
});
});
You can set which yAxis a series is plotted against by using the yAxis: <index> value in the series setup. For example:
...
{
name: 'Pressão H (Rotor 176mm)',
color: '#FF0000',
type: 'spline',
data: [14.1,13.9,13.7,13.45,13.2,12.8,12.45,12.1,11.65,11.3,10.7,10.27,9.8,9.2],
tooltip: {
valueSuffix: 'mca'
},
yAxis: 1,
}
...
Here is a very quick example of it. You have 2 xAxis and 3 yAxis. No idea if this is how you want to display it but this shows you how to move the axis around.
