bar pointPlacement works bad in get one data - javascript

When using the pointPlacement in highcharts when data is more than 1 it works fine, but when get one data from server all bars compress to one bar.
Sorry my English is bad

you can try my code here
try the normal code

That is a Highcharts bug reported here: https://github.com/highcharts/highcharts/issues/11800
As a workaround you can set pointRange: 1:
plotOptions: {
column: {
pointRange: 1,
...
}
}

customized tooltip and linking values to formfields -- highcharts / columnrange

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;
}
},

Highcharts (JavaScript): Change color of column if condition is met

I want to create a dynamic chart that shows all bars in the same color except for the person, who looks at it (in this case: The person who is represented by Afrika, Amerika, etc. Do you have any idea how to do it (in an easy way)?
Thanks in advance!
Highcharts code from https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/bar-basic/
Highcharts.chart('container', {
chart: {
type: 'bar'
},
title: {
text: 'Historic World Population by Region'
},
subtitle: {
text: 'Source: Wikipedia.org'
},
xAxis: {
categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
title: {
text: null
}
},
yAxis: {
min: 0,
title: {
text: 'Population (millions)',
align: 'high'
},
labels: {
overflow: 'justify'
}
},
tooltip: {
valueSuffix: ' millions'
},
plotOptions: {
bar: {
dataLabels: {
enabled: true
}
}
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'top',
x: -40,
y: 80,
floating: true,
borderWidth: 1,
backgroundColor: ((Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'),
shadow: true
},
credits: {
enabled: false
},
series: [{
name: 'Year 1800',
data: [107, 31, 635, 203, 2]
}]
});
You can simply set color for the point in data:
Highcharts.chart('container', {
series: [{
type: 'bar',
data: [43934, {
y: 52503,
color: 'red'
}, 57177, 69658, 97031, 119931, 137133, 154175]
}]
});
If you want to change the color depending on some condition, you can use update method for point, for example in load event:
chart: {
events: {
load: function() {
Highcharts.each(this.series[0].points, function(p) {
if (p.y > 8) {
p.update({
color: 'red'
});
}
});
}
}
}

How to reduce HighStock chart gap between candles?

I'm using candlestick chart of HighChart-HighStock. I want to reduce the gap between candlesticks. It's not so bad when it's on a wide range zoom. But when I zoomed the chart a lot, the padding between candle makes me annoyed because they are too wide apart.
I tried setting pointPadding of plotOption&xAxis to 0, but nothing happened. How can I shrink this gap?
Zoomed chart - too wide gap between candlestick
Wide view chart - not so bad

You need to set the series.pointPadding combined with series.groupPadding (equal to zero) to achieve the expected effect. Here is the example: https://jsfiddle.net/ahxrk5zq/
series: [{
type: 'candlestick',
name: 'AAPL Stock Price',
data: data,
groupPadding: 0,
pointPadding: 0.04,
dataGrouping: {
units: [
[
'week', // unit name
[1] // allowed multiples
], [
'month',
[1, 2, 3, 4, 6]
]
]
}
}]

Align second scatter series to the side similar to how column and bar charts do using HighCharts

I am creating a chart and have so far found that a scatter and errorbar combination chart is the best fit. I have hit a problem when adding an extra pair of series that because I have used a scatter, that they are placed on top of each other.
This is the standard view for the chart which is correct:

I have taken a look through the API and I have tried to use other chart types like Line and Column and although they do align correctly, the error bar pretty much disappears because those chart types start from zero. I've also tried pointPlacement but that just moves them both into the middle. Is what I am trying to do just not possible using a scatter?
You should use pointPlacement, but set per particular series. I prepared a minified demo for you:
series: [{
type: 'scatter',
pointPlacement:-0.2,
data: [51,73]
},{
type: 'scatter',
pointPlacement:0.2,
data: [8,7.6]
},{
type: 'errorbar',
pointPlacement:-0.2,
data: [[48, 51], [68, 73]]
}, {
type: 'errorbar',
pointPlacement:0.2,
data: [[6, 8], [5.9, 7.6]]
}]

Highcharts Crosshairs not working

I have what I'd consider a relatively simple Highcharts chart that I want to use shared crosshairs, but for some reason, I can't get my tool tip to work properly. Here is my javascript code:
var myChart = new Highcharts.Chart({
chart: {
renderTo: 'container',

},
yAxis: [{
title: {
text: '% Change',
align: 'middle',
margin: 15,
},
reverse: false,
opposite: false,
},
{
title: {
text: 'actual amount',
align: 'middle',
margin: 15,
},
reverse: false,
opposite: true,
}, ],
title: {
text: 'Comparison Chart',
align: 'center',
margin: 15,
},
series: [{
pointInterval: 86400000,
name: 'Your actual amount',
type: 'spline',
yAxis: '1',
color: '#4572A7',
data: [[1291248000000, 4140],
[1291334400000, 342],
[1291420800000, 56],
[1291507200000, 58],
[1291593600000, 712],
]},
{
pointInterval: 86400000,
dashStyle: 'ShortDashDot',
name: 'Other\'s %',
type: 'spline',
yAxis: '0',
color: '#89A54E',
data: [[1291248000000, 47.02],
[1291334400000, -28.68],
[1291420800000, -59.98],
[1291507200000, 182.14],
[1291593600000, -12.81],
]},
{
pointInterval: 86400000,
dashStyle: 'ShortDash',
name: 'Your %',
type: 'spline',
yAxis: '0',
color: '#AA4643',
data: [[1291248000000, 246.73],
[1291334400000, -91.74],
[1291420800000, -83.63],
[1291507200000, 3.57],
[1291593600000, 1127.59],
]},
],
});
The only thing I spotted was that in the JSON above you've put toolTip whereas in the highchart examples it's tooltip (all lower case).
